Closing ----------------------------------------------------------------------------- 1. Introduction ----------------------------------------------------------------------------- Alien: Isolation was released around October of 2014 (date may vary by system), and marks one of the most ambitious Alien games put on the market to date. Arguably, it might be one of the only "Alien" games (as I'm not aware of any others using the title of the first movie), but I digress. The game was met with mixed reception, but as a long-time Alien fan, I found the game had no equal. It accomplished what no other Alien (or Aliens) game had done to date: deliver a game in the Alien(s) universe that embraced the survival and horror elements of the franchise and took them to their full potential. Your personal feelings on the survival and stealth mechanics may vary, but waxing adoration aside, my goal is simple: to provide you with a quick and painless guide to finding all those pesky blueprints. "Blueprint guides have been done to death!" you might say, and you are right. But after scouring the Internet far and wide, I kept finding that guides were either sparse with instructions, dropped off completely after listing the v2 blueprints, or the details were exclusively in video format (ew). Well, for those kindred luddites out there, rejoice! My guide is pure text! For convenience, the blueprints are listed twice, first in the order you'll [most likely] run across them in the story (so as to avoid missing blueprints along the way) and then in a straightforward v1, v2, v3 format for those just looking for one blueprint in particular. The former was much harder to find online, and any time I replay Alien: Isolation (which is probably far too often), I'm constantly frustrated that no one has put such a guide together yet. I found myself taking notes on replays to avoid missing anything, and finally had the stray thought, why not just put it all together in one nice, easily accessible location? Well, lucky you, my frustration got the better of me, and I put one together. So I guess we both get to reap the benefits. So without further ado, on with the guide! ----------------------------------------------------------------------------- 2. Disclaimers and Guide Tips ----------------------------------------------------------------------------- 1: As the story events make for the best landmarks, some light spoilers might be contained in the descriptions. Details will be kept vague, save for those which were necessary to make navigation as painless as possible. After considerable review, I'm pleased to say that my guide should be free of any major plot points, and seeks to only reference the broadest of objectives/events. If you are aiming to avoid even a fleeting reference to objectives or missions, please read with care! 2: Due to the open-exploration offered by Alien: Isolation, it's entirely possible to do most of these in any order you feel like. Some have pretty narrow windows to find, and I'll try to indicate that where I can. In general, it is my goal to list the blueprints in the order at the earliest they are available. 3: I've come to find out that older (v1 and v2) blueprints will disappear from the environment once you pick up a higher level blueprint for the same item/craft. These seems pretty nature, considering that the older blueprint will have been made obsolete, but nevertheless, if you missed a blueprint and it just isn't showing up, make sure you haven't gotten a more advanced blueprint already. It can be difficult to tell which version you have, so I'm happy to try and break it down. The descriptions will contain very subtle hints as to which version of craft you are holding. The descriptions are only visible when you hit L1 on an item from crafting menu (the craft/build menu). v2 crafts will contain the phrase "This upgraded version..." *with the exception of the medikit, which adds "This advanced version restores more health" v3 crafts will contain the same phrase as v2, but also add to the end, "It will start to emit a noise that will attract a lot of attention..." 4: For simplicity, most of my directions will be given using cardinal directions, relative to where the location is on the map. This is probably more consistent than me using left and right, which I barely know the difference between as it is. So if ever in doubt, look at the map. ----------------------------------------------------------------------------- 3. Blueprints - Story Order ----------------------------------------------------------------------------- Medikit v1 Sevastapol Spaceflight Terminal: Arrivals and Departures -found starting in Mission 2 Interestingly, this blueprint is one of two places. After arriving in Sevastapol (after climbing the ladder from the baggage conveyors), you'll make your way to a wide open area with a giant Sevastapol model in the middle. You'll have to restart the power here using the desk up the stairs here, and you'll find a message titled "Moved Our Stash" in the computer. This contains the code to a door in plain view from the terminal (behind the model, now), next to the door you entered from. You'll have to restore power to use it. The blueprint is in this locked room. Alternatively, if you turn around and head straight through the large doors to the next room, after ducking under a live wire, you'll find the blueprint on a yellow bench right in front of you. It's hard to miss, but as you won't be coming back to this place until about Mission 11, you might want to make sure you grab it here. Smoke Bomb v1 SysTech Spire: Lower Level (Tech Support) -found starting in Mission 3 After sneaking (or sprinting) your way out of the Lobby, you'll make you way down the stairs two floors, and over to a reception desk with Tech Support written across it (doors on the way will also read "Tech Support"). In here you'll find the revolver and a key; the key opens a door in the short, dark hallway in this reception corner. The blueprint is on the other side of one of the desks/workbenches in the center of the room beyond this door. Flashbang v1 SysTech Spire: Lower Level (Tech Support) -found starting in Mission 3 This blueprint can be found immediately after the last one (or before). To recap, after sneaking (or sprinting) your way out of the Lobby, you'll make your way down the stairs two floors, and over to a reception desk with Tech Support written across it (doors on the way will also read "Tech Support"). In here you'll find the revolver and a key; the key opens a door in the short, dark hallway in this reception corner. Inside the door is the room labeled "Tech Support" on the map. To the North you will see a dark hallway that ends in a small, round room. The blueprint is on the wall to your right as you enter this small blue room. Noisemaker v1 SysTech Spire: Seegson Communications (Observation Deck) -found starting in Mission 4 After entering Seegson Communications, you'll want to wind you way around this first floor hallway, open the door to the stairs, and go up to the second floor. Here you'll see a door blocked off by a brace just across the stairs doorway (due North). This leads to a back set of rooms, one of which looks like a small dining area with a radio on the counter. The blueprint is on the table in this room. EMP Mine v1 SysTech Spire: Seegson Communications (Observation Deck - Internal Communications) -found starting in Mission 4 This is found towards the end of the Seegson Communications section, in the same area where you are tasked to re-establish contact. West of the terminal marked as your objective (or where you completed the objective, if you've already done it), you'll see a doorway leading to a small room with a save point. The blueprint is on the desk in here, and should be visible from the doorway. Pipe Bomb v1 SciMed Tower: San Cristobal Medical Facility (Crisis Stabilization Unit) -found starting in Mission 5 After discovering the code to leave the "Psychiatric Ward", use it to exit the area (door to the South labeled "Staff Quarters"). Keep going down the hall to another door labeled "Staff Quarters" at the end. Instead of entering the door, follow the hall right next to it (to the East) and descend down a short flight of steps. Enter the door with "Psychotropic Clinic" written across it (on your right). The blueprint is on one of the desks in this room. Molotov v1 SciMed Tower: San Cristobal Medical Facility (Primary Care Floor - Security Desk) -found starting in Mission 6 After you use the elevator to leave the Crisis Stabilization Unit floor, you'll have to solve a "puzzle" in the small starting area of mission 6. Once you solve it, you'll drop into a sort of bunk room. From this room, I recommend taking the hallway to the North (or right), all the way around to the small office in the corner designated "Security Desk" on the map (it's also on the wall next to the entrance). The blueprint is in this room, next to the terminal. Smoke Bomb v2 SciMed Tower: Seegson Synthetics (Facility Observation - Procedural Observation) -found starting in Mission 7 You'll have just gotten out of the medical facility and you'll eventually drop into an area where you find you need to repair an elevator. Follow the vent on the wall here, and then scoot to the floor vent from the exit of that one, and follow it around to the exit on the other side of the room, where you'll climb out and find a ladder to the second floor. Climb the ladder and circle around the hallway up here, stopping by the room on the West side (there's a save point inside). The blueprint is next to the entrance, on the wall. Flashbang v2 SciMed Tower: Maintenance Deck (Transit Control) -found starting in Mission 8 After your adventure through Seegson Synthetics, you'll return to the transit station. Your next stop is the Maintenance Deck. This takes you East from the transit station and to a door in the Northeast corner past the stairs. Follow the hall beyond to an elevator, and when the elevator stops, you'll find a pretty large grey box right in front of you. The blueprint is lying on this box. Medikit v2 SysTtech Spire: Upper Level (by Transit Station) -found during Mission 10 NOTE: While this blueprint should be available any time after chapter 10, I have not found this true in practice. The vent next to the locked door continues to show as "locked" even after it has been cut down. For me, at least, getting the door code is -essential- to getting this blueprint, and the code can only be gotten in Mission 10 (as far as I'm aware). This is probably the most complicated blueprint to acquire in the game. You'll eventually head back to the SysTech Spire (after your trip down memory lane with Marlowe). The door is just up the stairs from the transit station on the east side. The code can only be acquired by talking to four NPCs in this level, and for some reason the order seems to be critical. The first three NPCs are in the Lobby (East from the transit station, and then North to a large room with a giant engine suspended overhead). Two guys will be milling around the ring of desks in the middle here. These will be the first group. The next is on the second floor here, on the West side. You'll see a lower side section filled with tables and chairs, and a woman will be here. She is the third NPC. The last NPC is all the way back in the room marked "Tech Support" on the map (out the upper level of the Lobby, and through the Southeast exit and down two flights of stairs). A reception desk will be through this door, and you'll want to go through the hallway behind this desk. The room beyond is labeled Tech Support on the map. There will be a hallway to the north of this room that ends in a small round room illuminated by blue light. The last person is here, and she should give you the code. As mentioned, there's technically a vent you can cut through with an upgraded cutting torch, but for whatever reason, even after I cut through it, the vent still read "locked" (even though I see clean through the hole). Noisemaker v2 SysTech Spire: Upper Level -found starting in Mission 10 You'll eventually be tasked to lock a bunch of doors in this mission. In this process, you'll need to look at a computer and run a program to unlock a file (out Southeast exit on second floor of Lobby, following signs for "Tech Support" and then "Server Hub Administration" if you need more help getting here; note, this room will not be accessible until you activate the three locks in that area). Unlocking the file should eventually unlock the door to the North of this room (labeled "Server Farm"), which leads to a hall. At the end of the hall, to the West, will be a door (also labeled "Server Farm"). Inside the room (down the short series of steps) will be a glowing white table. The blueprint is on this table. EMP Mine v2 Habitation Tower: Galleria Upper Concourse -found starting in Mission 11 After you finish changing (from your "walk"), you'll be back in the Spaceflight Terminal. You'll eventually come back out into the room labeled Baggage Claim on the map. Your objective will be to take an elevator that leads to the Habitation tower. Once here, you'll want to take the long hall across the lobby you stop at and follow it to the end. You'll need to activate the cleaning robot here to open the way forward. Follow it through the path it creates, and you'll find another wall vent you can take around. When you come out, you'll see a table directly in front of you with the blueprint staring right at you. Molotov v2 Seegson Synthetics: Seegson Synthetics Administration (by Sales Agreements) -found starting in Mission 12 Once you arrive at Seegson Synthetics this time, your first task will be to power up a door. Once through, you'll follow a path that eventually leads to large office with a bunch of figures on display. Once you find the exit from this room, you'll see a sort of reception desk. Past the reception desk (South) is a short series of steps leading to a room labeled as Sales Agreements on the map. A corpse lies outside the room designated Sales Agreements, and the blueprint is lying next to him. Flashbang v3 SciMed Tower: San Cristobal Medical Facility (Primary Care Floor) -found starting on Mission 15 You'll revisit the Primary Care Floor during this chapter, and you'll want to make your way to the Ambulance Bay (marked as the objective on your map). In this room, the blueprint is lying on one of the red trays/beds right as you walk inside. NOTE: The next 4 blueprints are not on any story route. You will need to make a detour to acquire these before getting too far into Mission 16 (the point of no return), but the earliest you can conceivably get them is towards the tail end of Mission 15. You may seek them out in any order you please. Pipe Bomb v2 Engineering (Maintenance Deck - Workshop) NOTE: If you have found the Pipe Bomb v3 blueprint already, this blueprint will not be here. For this reason, it has been listed first. -found starting in Mission 15 This blueprint requires the security access tuner level 3. You can head straight for the blueprint as soon as you've acquired the level 3 tuner, or you can wait until the start of Mission 16, which I felt offered a bit more breathing room, but it's entirely up to you. This one is a little odd, as it would seem the Pipe Bomb v2 and v3 blueprints become available at the same time. But as noted, if you grab v3 first, v2 disappears. To find the blueprint for v2: -take the tram to Engineering -once here, head East, and then head South (both doors are labeled "Reactor Coolant Plant") -at the end, if you haven't already, there's a shutter you'll need to burn the panel off of to open (requires upgraded cutting torch) -an elevator is in this room (on the West side) that will take you to Engineering -from the elevator you'll head West (through a door labeled "Facility Management"), North, and then West once you reach a broken door labeled "Tool Shop" -follow this hallway around and follow this narrow path to another door that needs to have a panel cut off with the fully upgraded cutting torch -this will lead to an industrial room labeled Workshop on the map (there is a large lunar-landing looking piece of machinery in here, as well as dune buggy-like piece of equipment, the latter you had to move to proceed when you came through this area originally) -the door the blueprint is in the Northwest corner of this room (door requires the security access tuner level 3 to open) Pipe Bomb v3 SciMed Tower: Transit Station -found starting on Mission 15 This blueprint requires the security access tuner level 3. You can head straight for the blueprint as soon as you've acquired the level 3 tuner, or you can wait until the start of Mission 16, which I felt offered a bit more breathing room, but it's entirely up to you. -take a tram to the SciMed Tower -from the tram, head west -at the junction (once you're up the stairs), turn right and head the door into a small room facing a bunch of windows -take the stairs to the right and you'll pass a small reception area on your right; the blueprint is in here, but you can't get to it from this room -keep going straight from the stairs, through the door, and turn right in the next room, and right again to find a door that leads directly into the reception area (the fully upgraded security access tuner is needed to crack it) -the blueprint is across the reception booth on the wall to your left Noisemaker v3 Habitation Tower: Galleria Lower Concourse -found starting on Mission 15 This blueprint requires the security access tuner level 3. You can head straight for the blueprint as soon as you've acquired the level 3 tuner, or you can wait until the start of Mission 16, which I felt offered a bit more breathing room, but it's entirely up to you. -You -must- head to Solomon's Habitation Tower by tram (you cannot get it during your foray through this tower in Mission 17) -from the transit station, take the stairs (headed Northwest on the map) -almost immediately after the stars is a door on your left (South side) that you can crack with the fully upgraded security access tuner -the blueprint is on the desk in here (and is actually visible through the window) NOTE: I've read it's possible to grab the blueprint through the window, but that has never worked for me. Molotov v3 SysTech Spire: Lobby and Technical (Kitchen) -found starting on Mission 15 This blueprint requires the security access tuner level 3. You can head straight for the blueprint as soon as you've acquired the level 3 tuner, or you can wait until the start of Mission 16, which I felt offered a bit more breathing room, but it's entirely up to you. -take a tram to the Systech Spire -head East, and then North to the Lobby (has a giant engine hanging in it) -on the upper-level (West side) is a rest/dining small area with tables; a door is labeled "Kitchen" on the South side of the side area -the blueprint is hanging off the counter in this room Smoke Bomb v3 SysTech Spire: Seegson Communications (Monitoring Rooms) -found starting in Mission 16 NOTE: You can grab this one before the previous 3 blueprints, but because it's on the way to progressing with the story, and the others are diversions, this is being listed after the others. You'll arrive back in Seegson Communications during this chapter, and you'll very quickly pass a very familiar reception booth. Just past this reception (heading West) will be a shaft that requires an upgraded cutting torch (on the South side of the hallway). The other end of this shaft is all the way down this hallway (heading West), through the doorway there, and all the way around the giant pipes in here. Both require the upgraded cutting torch, but whichever entrance you cut through, in the shaft, a branching path to the South leads to a small room. The blueprint is on the wall in this small room only accessible by this vent. EMP Mine v3 Sevastapol Spaceflight Terminal: Arrivals and Departures (Passenger Lounge) -found starting in Mission 15 You'll return to the Spaceflight Terminal Passenger Lounge towards the end of Mission 17 (after an unforgettable adventure going back-and-forth in a long hallway to restore power in order to leave the Habitation Tower), but it should technically be possible to backtrack this way as early as Mission 15 (using the elevator in Habitation Tower: Galleria Upper Concourse; more notes on this in the other list). As you'll be coming through this area anyway (at the end of Mission 17), it might be easiest to grab this on the way, but if you want take advantage of the upgrades sooner, more power to you. To give you story landmark for Chapter 17 this would be on the way to the tow platform. The blueprint is in a small room on the ground level of this room, Southwest side (must cut through a panel with the fully upgraded cutting torch to get inside). ----------------------------------------------------------------------------- 4. Blueprints - List ----------------------------------------------------------------------------- This is just a list of the blueprints in a way that might be easier to read if you are not going through the story. To take this into account, I'll try to describe how to reach them both, as if coming to them from the story, and how you might get there from later missions (where available). ----------------------------------Medikit---------------------------------- v1 - Sevastapol Spaceflight Terminal: Arrivals and Departures -found in Mission 2 Interestingly, this blueprint can be in one of two places. After arriving in Sevastapol (after climbing the ladder from the baggage conveyors), you'll make your way to a wide open area with a giant Sevastapol model in the middle. You'll have to restart the power here using the desk up the stairs here, and you'll find a message titled "Moved Our Stash" in the computer. This contains the code to a door in plain view from the terminal (behind the model, now), next to the door you entered from. You'll have to restore power to use it. The blueprint is in this locked room. Alternatively, if you turn around and head straight through the large doors to the next room, after ducking under a live wire, you'll find the blueprint on a yellow bench right in front of you. If you somehow passed this up, the earliest chance you're probably going to get to come back here is in Mission 11. So if you're coming back in a later mission, one path is as follows (it's kind of a journey): -take the ram to the Habitation Tower -from the transit station, head Northwest, turning Southeast at the junction (opposite the Martial's Bureau entrance) -take the stairs down, to the Northwest -follow them down a long hallway and up a short flight of steps; you can stairs in the distance, but turn West/Southwest and head through the door here instead. -take the collapsed ramp up to the East -head South down this hallway, until it turns West -there's another shutter here to the South; it should be open now (if not, you'll need to take the long detour using the door to the West, through the floor chutes). -follow the path behind the shutter to the West (if you have to take the long detour, you'll come out in this same hallway by the other end); an elevator to the Spaceflight Terminal is on the North side of the lounge on the other side -Once in the Spaceflight Terminal, from the elevator, head North, past the busted conveyors, until you get to a dead end -Use the floor chute to come out in a small a bar in the Passenger Lounge -Loop your way around the stairs to head to the West exit of the Passenger Lounge (labeled "All Departures") -the blueprint should be on the yellow bench just before the live-wire dangling over the checkpoint v2 - SysTech Spire: Upper Level (by Transit Station) -found in Mission 10, and possibly only mission 10 This is probably the most complicated upgrade in the game. This is found in SysTech Spire (you'll head back here after your trip down memory lane with Marlowe). The door is just up the stairs from the transit station on the east side. Technically, you should be able to grab this one at any point between Mission 10 and Mission 17, but the for this door can -only- be acquired by talking to three groups of NPCs in this level. Please take note, as for some reason the order in which talk to them seems to matter. The first two groups are in the lobby (where you got the Security Access Tuner; there's a giant engine suspended above the middle of the room). Two guys will be milling around the ring of desks in the middle here- these will be the first group. The second is on the second floor here, on the west side. You'll see a lower side section filled with tables and chairs, and a woman will be here. She is the second group. The last is all the way back in the room marked "Tech Support" on the map (out the upper level of the Lobby, and through the Southeast exit and down two flights of stairs). A reception desk will be through this door, and you'll want to go through the hallway behind this desk. The room beyond is labeled Tech Support on the map. There will be a hallway to the north of this room that ends in a small round room illuminated by blue light. The last person is here, and she should give you the code. There's technically a vent you can cut through with an upgraded cutting torch, but for whatever reason, even after I cut through it, the vent still reads "locked" (even through I see clean through the hole). v3 - There is no v3. Anyone who says otherwise is lying. ---------------------------------Smoke Bomb--------------------------------- v1 - SysTech Spire: Lower Level (Tech Support) -found starting in Mission 3 After sneaking (or sprinting) your way out of the big lobby in this level (has a giant engine hanging over a ring of desks, with large screens on the wall behind the engine), you'll make you way down the stairs, and over to a reception desk with Tech Support written across it. In here you'll find the revolver and a key; the key opens a door in the short, dark hallway in this reception corner. The blueprint is on the other side of one of the desks/workbenches in the center of the room. If you're coming back for this in a later chapter, you can follow these directions to find the blueprint: - take a tram to the SysTech Spire -head East, and then North from the transit station to the open area marked Lobby on the map (has a giant engine hanging over it). -head upstairs exit the Southeast corner -go down two flights of stairs and enter the door labeled "Tech Support" -the Tech Support desk is through this door, to the Northwest; head inside -a hallway is at the back of the reception area (to the North); follow it to the room labeled "Tech Support" on the map -the blueprint is on the other side of one of the desks in this room v2 - SciMed Tower: Seegson Synthetics (Facility Observation - Procedural Observation) -found starting in Mission 7 You'll have just gotten out of the medical facility and you'll eventually drop into an area where you find you need to repair an elevator. Follow the wall vent here, and then scoot to the floor vent from the exit of that one, and follow it to the other side of the room where you'll find an exit leading to a ladder. Climb the ladder and circle around the hallway up here, stopping by the room on the West side (there's a save point inside). The blueprint is next to the entrance, on the wall. For instructions on how to get here after Mission 7: -take a tram to SciMed tower -head West up the stairs -at the junction, head North into a small waiting room with windows looking out into space -head up the stairs (going East) and go through the door ahead of you, then turn and use the elevator on the North wall -from the elevator, head East, following the sign for "Seegson Control Center" -take the ladder down (on the South side of the next room) -follow this catwalk all the way to the end and take the elevator to Synthetic Storage -provided the way is clear, head South into the Technician Training room and take the ladder in the Southeast corner -this hallway forms a ring; take it around and the blueprint will be on the wall inside the room to the East (next to the entrance) v3 SysTech Spire: Seegson Communications (Monitoring Rooms) -found starting in Mission 16 You'll arrive back in Seegson Communications during this chapter, and you'll very quickly pass a very familiar reception booth. Just past this reception (to the East) will be a shaft on the South/left-hand side that requires a fully-upgraded cutting torch. The other end of this shaft is in the corridor that you reach by walking past reception, all the way East, down a few steps and through the door to a room with some giant pipes. If you loop around the pipes in this room, you'll find the other end of the shaft, which also requires a fully upgraded cutting torch. Whichever entrance you cut through, in the shaft, a branching path to the South leads to a small room. The blueprint is on the wall in this small room only accessible by this vent. If you're not at the start of Mission 16 (but not past the point of no return), you should also be able to get there using similar instructions: -take a tram to the SysTech Spire -head East from the transit station and North to the Lobby (a giant engine hangs over this room) -the door directly across leads to Seegson Communications -once in Seegson Communications, head straight past the reception desk (heading East) -one entrance to the shaft is behind a vent cover on the left (to the South), just past reception; it requires the fully upgraded cutting torch -for reference, the other entrance is further down, all the way to end of this hallway (heading East). You'll have to walk through a door and loop around some giant pipes to get to it (they lead to the same shaft)-you can take either entrance, the room with the blueprint is accessed from a branching path in this shaft, to the South ----------------------------------Flashbang---------------------------------- v1 - SysTech Spire: Lower Level (Tech Support) -found starting in Mission 3 After sneaking (or sprinting) your way out of the big lobby in this level (has a giant engine hanging over a ring of desks, with large screens on the wall behind the engine), you'll make you way down the stairs, and over to a reception desk with Tech Support written across it. In here you'll find the revolver and a key; the key opens a door in the short, dark hallway in this reception corner. Inside the door is the room labeled "Tech Support" on the map. To the North you will see a dark hallway that ends in a small, round room. The blueprint is on the wall to your right as you enter this small blue room. For instructions on how to get here after Mission 3: -take a tram to the SysTech Spire -head East from the transit station and Then North to the Lobby (room with big engine hanging from the ceiling) -head upstairs and take the Southeast exit -head down two levels and through a door labeled "Tech Support"; you should see a little reception desk straight ahead and to the right with the same label across it in yellow -behind this desk is a short hallway; take it to the room labeled Tech Support on the map -there is a short hallway to the North that ends in a small, round room illuminated by blue light -the blueprint is on the cabinet/wall next to the entrance v2 - SciMed Tower: Maintenance Deck (Transit Control) -found starting in Mission 8 After your adventure through Seegson Synthetics, you'll return to the transit station. Your next stop is the maintenance deck. This takes you East from the transit station and to a door in the Northeast corner past the stairs. Follow the hall beyond to an elevator, and when the elevator stops, you'll find a pretty large grey box right in front of you. The blueprint is lying on this box. If you're coming back here later, you can get to this room by: -take tram ot the SciMed Tower -head east from the transit station and up the stairs -there will two doors on the North side of these stairs, you want the closer one (the further door is the one used to get to the Maintenance Deck originally)-in this room you'll find a vent, which you can take back up to the Maintenance Deck v3 SciMed Tower: San Cristobal Medical Facility (Primary Care Floor) -found starting on Mission 15 You'll revisit the Primary Care Floor during this chapter, and you'll want to make your way to the Ambulance Bay (marked as the objective on your map). In this room, the blueprint is lying on one of the red trays/beds right as you walk inside. For the steps on how to get here from a different chapter, you can follow the instructions here: -take a tram to SciMed tower -head West up the stairs -keep going North here (you will probably need an upgraded cutting torch for this door) and you see an elevator dead ahead that will take you to the Primary Care Floor -in the big fiery Medical Reception room, head West; like many doors in later missions, they will appear to be locked, but aren't actually -in the next hallway, follow the bend north -there will be a door to the Northeast that give you a straight shot at the Ambulance Bay, but on later missions it will be locked; instead, you will probably need to head West, follow the bend North, and take one of the hallways West to make the same journey (which way you take is entirely up to what is convenient. In some Missions, enemy placement might make it more convenient to take the middle hallway West, for instance, and cut through the rooms that join the Westward hallway furthest North) -however you get there, you should reach a junction that is adjacent to a room labeled Power Plant on the map. You want to instead head North to the Ambulance Bay, where the blueprint is lying on a red stretcher/bed ---------------------------------Noisemaker--------------------------------- v1 - SysTech Spire: Seegson Communications (Observation Deck) -found starting in Mission 4 After entering Seegson Communications, you'll want to wind you way around, open the door to the stairs, and go up to the second floor. Here you'll see a door blocked off by a brace just across the stairs doorway. This leads to a back set of rooms, one of which looks like a small dining area with a radio on the counter. The blueprint is on the table in this room. If you're coming back here later, you can get here by: -take a tram to the SysTech Spire -head East from the transit station and then North to the Lobby (has a giant engine suspended over it) -head straight to the elevator on the North side of this room to go to Seegson Communications -in Seegson Communications, follow the main hall all the way around (East, then North, then West) to the end -there will be a door here that leads to the second floor (you unlock during Mission 4 using the terminal in the nearby room). -at the top of the second floor is a door directly across the hall (it may no longer have the brace if you removed it already) -this door leads to a back hallway; follow it East to a small dining room with a table and chairs; the blueprint is on this table v2 - SysTech Spire: Upper Level -found starting in Mission 10 You'll eventually be tasked to lock a bunch of doors in this mission. In this process, you'll eventually need to look at a computer and run a program to unlock a file (if you need more help getting here, go to Tech Support, follow signs for Server Hub Reception). Unlocking the file should eventually unlock the door to the North of this room (labeled "Server Farm"), which leads to a hall. At the end of the hall, to the West, will be a door (also labeled "Server Farm"). Inside the room (down the short series of steps) will be a glowing white table. The blueprint is on this table. Should you come looking for it later, you can get here by a few different ways, depending on what doors you unlocked long the way during Mission 10. -presuming the worst, take the tram to the SysTech Spire -from here, head East and then North to the Lobby (with a giant engine suspended overhead) -head upstairs and take the Southeast exit on the upper-level -from here, the fastest way might be to go one level down, through a door marked "Server Hub Reception" and "Staff Access Only" -if you walk straight through the room behind this door, you'll see a door labeled "Server Hub Reception" (only) across from you -head through this door and straight across (slightly to the right) you'll see a door labeled "Server Farm" -beyond this door, at the end of the hall and to the West, is the illuminated table with the blueprint *If the "Server Hub Reception" and "Staff Access Only" door is locked for some reason, you can go down another floor to the "Tech Support" door. You'll see a receptionist desk labeled "Tech Support" ahead, but if you keep walking to the door ahead labeled "Server Hub Reception," you can take these stairs up a few floors to the same door (the one marked "Server Hub Reception" only, mentioned above, which leads to a door with "Server Farm" written across it) v3 - Habitation Tower: Galleria Lower Concourse -found starting on Mission 15 (and can realistically only be acquired until the point of no return in Mission 16, so the window is pretty narrow) This blueprint requires the security access tuner level 3. You can head straight for the blueprint as soon as you've acquired the level 3 tuner, or you can wait until the start of Mission 16, which I felt offered a bit more breathing room, but it's entirely up to you. -you must head to Solomon's Habitation Tower by tram (you cannot get it during your foray through this tower in Mission 17) -take the stairs (heading Northwest) and almost immediately after the stairs is a door on your left (South side) that you can crack with the security access tuner if fully upgraded -the blueprint is on the desk in here (and is actually visible through the window) NOTE: I've read it's possible to grab the blueprint through the window, but that has never worked for me. ----------------------------------EMP Mine---------------------------------- v1 - SysTech Spire: Seegson Communications (Observation Deck - Internal Communications) -found starting in Mission 4 This is found towards the end of the Seegson Communications section, in the same area where you are tasked to re-establish contact. West of the terminal marked as your objective (or where you completed the objective, if you've already done it), you'll see a small a door leading to a small room with a save point. The blueprint is on the desk in here, and should be visible from the doorway. If you missed or are coming back later, you'll have to go all the way through Seegson Communications again. -take a tram to SysTech Spire -head East and then North to the Lobby (has big engine hanging in it) -head straight north to the elevator -the elevator will take you to Seegson Communications; once here you'll have to wind your way around the first floor, up to the second floor and East, where you'll hit Comms Control -from Comms Controls (on the map) head South to Internal Communications -there's a small room with a save station at the South part of this floor (almost the Southern tip of the map); The blueprint is in this room. v2 - Habitation Tower: Galleria Upper Concourse -found starting in Mission 11 After you finish changing at the start of this level, you'll be back in the Spaceflight Terminal. Once you arrive back in the large room marked as "Baggage Claim" on the map, you'll be tasked with taking an elevator to the South for the Habitation Tower. Once you arrive you'll want to take the long hall across the lobby and follow it East to the end. You'll need to activate the cleaning robot here to open the way forward. Follow it, and you'll find another vent you can take around. When you come out, you'll see a table directly in front of you with the blueprint staring right at you. For those trying to make their way back to this one later on, you can get here by doing the following (it's a bit of a trek): -take the ram to the Habitation Tower -from the transit station, head Northwest, turning Southeast at the junction (opposite the Martial's Bureau entrance) -take the stairs down, to the Northwest -follow them down a long hallway and up a short flight of steps; you can stairs in the distance, but turn West/Southwest and head through the door here instead. -take the collapsed ramp up to the East -head South down this hallway, until it turns West -there's another shutter here to the South; it should be open now (if not, you'll need to take the long detour using the door to the West, through the floor chutes) -you should have already activated the cleaning robot in a previous chapter, which should open the small path by the end of this hallway (on the North side) -through this small door opened by the cleaning robot, you'll enter a room with another wall shaft -when you come out of the other end of the wall shaft will be a desk right in front of you with the blueprint *if you have to take the long detour, you'll come across the table with the blueprint on the way to the hallway behind the shutter (just before entering a wall shaft that leads into the cleaning robots closet) v3 - Sevastapol Spaceflight Terminal: Arrivals and Departures (Passenger Lounge) -found starting in Mission 15 You'll return to the Spaceflight Terminal (large lobby from the beginning; there was a sequence where the Torrens passes by some windows here and Amanda makes a big deal about it) towards the end of Mission 17, on your way to the tow platform and after leaving a unique part of the Habitation Tower. It should technically be possible to backtrack this way as early as Mission 15 (using the elevator in Habitation Tower: Galleria Upper Concourse), but as you'll be coming through this area anyway (at the end of Mission 17), it might be more prudent to grab this then (entirely up to you). The blueprint is in a small room on the ground level of this room, Southwest side (must cut through a panel with the ion torch to get inside). If you're wondering how to get here earlier than Mission 17, you can the path below: -take the ram to the Habitation Tower -from the transit station, head Northwest, turning Southeast at the junction (opposite the Martial's Bureau entrance) -take the stairs down, to the Northwest -follow them down a long hallway and up a short flight of steps; you can stairs in the distance, but turn West/Southwest and head through the door here instead. -take the collapsed ramp up to the East -head South down this hallway, until it turns West -there's another shutter here to the South; it should be open now (if not, you'll need to take the long detour using the door to the West, through the floor chutes) -follow the path behind the shutter to the West (if you have to take the long detour, you'll come out in this same hallway by the other end); an elevator to the Spaceflight Terminal is on the North side of the lounge on the other side -Once in the Spaceflight Terminal, from the elevator, head North, past the busted conveyors, until you get to a dead end -Use the floor chute to come out in a small a bar in the Passenger Lounge -Loop your way around the stairs to head to the West exit of the Passenger Lounge (labeled "All Departures") -the blueprint should be on the yellow bench just before the live-wire dangling over the checkpoint ----------------------------------Pipe Bomb---------------------------------- v1 - SciMed Tower: San Cristobal Medical Facility (Crisis Stabilization Unit) -found starting in Mission 5 After discovering the code to leave "Psychiatric Ward", use it to exit the area (door to the south labeled "Staff Quarters"). Keep going down the hall to another door labeled "Staff Quarters" at the end. Instead of entering the door, follow the hall right next to it (to the East) and descend down a short flight of steps. Enter the door with "Psychotropic Clinic" written across it (on your right). The blueprint is on one of the desks in this room. Those coming back here later can get to the same area using these instructions: -take a tram to SciMed tower -head West up the stairs -keep going North here (you will probably need an upgraded cutting torch for this door) and you see an elevator dead ahead that will take you to the Primary Care Floor -in the big fiery Medical Reception room, head West to a door labeled "Emergency Room;" like many doors in later missions, they will appear to be locked, but aren't actually -in the next hallway, follow the bend north -at the junction, you'll need to head West, following the bend around to the North and follow it all the way down (you might have to get creative in how you get to this northern most hallway, depending on the threats in this level) -the hallway will bend to the West again and about halfway down on the North side is an elevator that will take you back to the Crisis Stabilization Unit -there are a few different ways to get to the same room from the elevator, but the fastest might to head South from the elevator -past the door will be a hallway; follow the ring around to the West as it curves South -enter the door on the West side labeled "Staff Quarters" and take it South, following it West around the bend -very shortly after the bend will be a door labeled "Psychotropic Clinic"; the blurprint is on the desk in here v2 - Engineering (Maintenance Deck - Workshop) NOTE: If you have found the Pipe Bomb v3 blueprint already, this blueprint will not be here. Both blueprints are only available with the third security access tuner upgrade, so it is very possible to get the v3 blueprint first by accident -found starting in Mission 15 This blueprint requires the security access tuner level 3. You can head straight for the blueprint as soon as you've acquired the level 3 tuner, or you can wait until the start of Mission 16, which I felt offered a bit more breathing room, but it's entirely up to you. This one is a little odd, as it would seem the Pipe Bomb v2 and v3 blueprints become available at the same time. To find it: -take the tram to Engineering -head East, and then head South (both doors are labeled "Reactor Coolant Plant") -at the end, if you haven't already, there's a shutter you'll need to burn the panel off of to open -an elevator is in the room behind the shutter (on the West side) that will take you to Engineering. -from the elevator head West (through a door labeled "Facility Management"), North, and then West once you reach a broken door labeled "Tool Shop" -follow this narrow path to a door that needs to have a panel cut off with the fully upgraded cutting torch -the door will lead to an industrial room labeled Workshop on the map (there is a large lunar-landing looking piece of machinery in here, as well as dune buggy-like piece of equipment, the latter you had to move to proceed when you came through this area originally) -the door to the blueprint is in the Northwest corner of this room (requires the security access tuner level 3 to open). v3 - SciMed Tower: Transit Station -found starting on Mission 15 This blueprint requires the security access tuner level 3. You can head straight for the blueprint as soon as you've acquired the level 3 tuner, or you can wait until the start of Mission 16, which I felt offered a bit more breathing room, but it's entirely up to you. -head to the SciMed Tower -from the transit station, you'll want to head West -turn North at the junction and through the door here into a small room facing out a bunch of windows -take the stairs (heading East) and you'll pass a small reception area on your right; The blueprint is in here, but you can't get to it from this room -keep going straight from the stairs (East), through the door, and turn right in the next room, and right again to find a door that leads directly into the reception area. -the fully upgraded security access tuner is needed to crack it. The blueprint is across the reception booth on the wall on the South side. -----------------------------------Molotov----------------------------------- v1 SciMed Tower: San Cristobal Medical Facility (Primary Care Floor - Security Desk) -found starting in Mission 6 After you use the elevator to leave the crisis stabilization unit floor, you'll have to solve a "puzzle" in the small starting area of mission 6. Once you solve it, you'll drop into a sort of bunk room. From this room, I recommend taking the hallway to the North (or right), all the way around to the small corner designated "Security Desk" on the map (it's also on the wall next to the entrance). The blueprint is in this room, next to the terminal. If coming back here from a later mission, you can get to the same area: -take a tram to SciMed tower -head West up the stairs -keep going North here (you will probably need an upgraded cutting torch for this door) and you see an elevator dead ahead that will take you to the Primary Care Floor
-in the big fiery Medical Reception room, head West to a door labeled "Emergency
Room;" like many doors in later missions, they will appear to be locked, but
aren't actually
-in the next hallway, follow the bend north
-at the junction, you'll need to head West, following the bend around to the
North slightly, taking the first door on the West side
-ahead you'll see a sign that reads "Staff Quarters"; head South at this
junction (or to your left)
-at the end you'll see another sign labeled "Security Desk"; head East into the
office here and you'll find the blueprint on the desk next to this terminal


v2 - Seegson Synthetics: Seegson Synthetics Administration (by Sales Agreements)

-found starting in Mission 12
Once you arrive at Seegson Synthetics this time, your first task will be to
power up a door. Once through, you'll follow a path that eventually leads to
large office with a bunch of figures on display. Once you find the exit from
this room, you'll see a sort of reception desk. Past the reception desk (South)
is a short series of steps leading to Sales Agreements (marked on the map). A
corpse lies outside the room designated Sales Agreements, and the blueprint is
lying next to him. 

If coming here after Mission 12, you can still get to this area by:
-take a tram to SciMed tower
-head West up the stairs
-at the junction, head North into a small waiting room with windows looking out
into space
-head up the stairs (going East) and then turn and use the elevator on the North
wall
-from the elevator, head East, following the sign for "Seegson Control Center"
-take the ladder down (on the South side of the next room)
-across the long catwalk, you'll see another ladder (on the East side at the
end); if you climb up this ladder, you can take the cart back North across the
pit
-beyond the door at the end will be an elevator which will take you back to
Seegson Synthetics Administration
-Once in Seegson Synthetics Administration, head straight across to a door
labeled "Sales Agreements"
-a reception desk will be ahead of you; go around it and toward the room behind
it
-a corpse is lying on the East side of the entrance to the room labeled Sales
Agreements on the map, and the blueprint is next to him


v3 - SysTech Spire: Lobby and Technical (Kitchen)

-found starting on Mission 15
This blueprint requires the security access tuner level 3. You can head straight
for the blueprint as soon as you've acquired the level 3 tuner, or you can wait
until the start of Mission 16, which I felt offered a bit more breathing room,
but it's entirely up to you. 
-take a tram to the SysTech tower
-head to the Lorenz Systech Spire's Lobby (large open area with the Engine
suspended overhead)
-on the upper-level (West side) is a rest/dining small area with tables; A door
is labeled "Kitchen" on the South side of the side area (requires the fully
upgraded security access tuner)
-the blueprint is hanging off the counter in this room
