FAQ [FAQS] ============================================================================== I. Introduction [INTRO] A. About the Walkthrough [BOUT] I write this for the "veteran" of the Assassin's Creed series; that is, new 'initiates' to the series will need to spend time familiarizing themselves with the mechanics of the game, especially combat, replaying memories, and the map and its legend. This, by no means, is meant to imply that the novice will be lost. Indeed, everybody should be able to utilize and gain from this walkthrough, but I shan't be treating you, my reader, like an idiot who needs me to hold his/her hand through the game. This is SPOILER-FREE with the exception of some new forms of combat that Ezio learns in the early missions of the game. Assassin's Creed: Revelations has veteran authors producing well-written guides. For the majority of what you must accomplish to achieve 100% synchronization, use them. This is limited solely to the Challenges. Do you have suggestions for improvement, alternate strategies, or found a mistake? Please, tell me, and I will correct and give due credit. (Be honest and tell me if you know this fact from another FAQ and/or website. Give me the URL of the guide, and I will give credit to both you and your source.) ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ B. Contacting the Author [MAIL] E-mail C. S. Halloran at his Gmail account. The username is my name as written on the above line sans the periods and the spaces. I will neither be able nor inclined to reply to all e-mails, depending upon their quality and content on the latter point. Please take it on faith that I have received the e-mail and will address it in the walkthrough's next update. *****READ THE FOLLOWING BEFORE E-MAILING ME***** I feel it should be unnecessary to say this, but in your e-mails, please BE AS SPECIFIC AS POSSIBLE when referencing challenges and/or this guide. Name the challenge or tell me precisely where in this walkthrough I erred and/or failed to figure out a better strategy. I am not psychic and will not be able to magically discern what you meant. If I cannot understand what you are getting at quickly, then I am not going to even try. Attempts to be specific that say "the memory where you the killed that guy..." or something equally vague will be considered failures at specificity. I will ignore rude e-mails and e-mails that have incomprehensible grammar, syntax, and/or spelling. (That especially includes text messaging and IM lingo.) I have take the time to write this FAQ clearly; return the favor. Read ALL of a section before asking me a question about it. If it is answered already in this FAQ, I reserve the right to be snide, rude, and/or sarcastic when and if I reply. If it is beyond the scope of these Challenges, I will ignore you. You ought to know that you should consult an appropriate walkthrough or FAQ. ============================================================================== II. About the Challenges [CHLN] For those who must have 100% Synchronization, these Challenges are necessary, time-consuming, and potentially frustrating. Most can be fulfilled during normal gameplay, but doing so requires conscientiousness and diligence. Each challenge is organized in two or three sets. The sets can be completed in any order, meaning Set 3 can be completed and its reward received before the completion of either or both of the previous sets in a given challenge. The benefit of these Guild Challenges over their similar counterparts in Assassin's Creed: Brotherhood is that you receive useful rewards upon the completion of specifics sets, namely a weapon and an unlocked ability activated whenever a faction is hired. The good thing is that these Challenges open up early in the game during Sequence 2. (If you do not see the message on your screen, look to your map. When you see the missions appear in the Mercenaries Guild and Thieves Guild locations in the Imperial District, these challenges are open. You need not complete the Guild missions to start satisfying these challenges.) This gives you plenty of time to casually and/or occasionally do the tasks to satisfy all requirements. I suggest that you combine your pursuit of their fulfillment with your moving around Constantinople collecting Treasure Chests and Animus fragments, liberating Templar Dens, defending Assassin Dens, sending your Assassin recruits on missions in the Mediterranean Defense minigame, and recruiting new assassins to replace the (Level 10) assassins you establish in dens in other cities. That said, some challenges will best be fulfilled through a focused campaign, particularly if your style of gameplay involves solving the problem of guards' alert level with combat (cf. Romani Guild, Set 1 challenges). I also suggest that you do these early. If you are seeking 100% synchronization, you need money as the price of the books by Sequence 7 rises outrageously. (You need approximately 350,000 akce for the books available in that sequence.) Additionally, there are many expensive landmarks to purchase in the Rebuilindg Constantinople minigame, and many missions on which you can send your Assassin Recruits cost akce.) A sustained focus on these guild challenges in Sequence 2 or 3 allows you to productively spend time that will allow the Rebuilding Constantinople minigame to increase your treasury and ownership of Constantinopolitan businesses and landmarks. ============================================================================== III. Assassin's Guild Challenges [ASGC] A. Challenge Set 1 [ASGC1] Reward: Assassins will be more effective when sent on missions. -- The probability of success of the first Assassin recruit sent on a mission will be ten percentage points higher. Call Assassins during a fight ----- 25 Form the habit of squeezing L2 once in combat mode. Particularly do this during missions to combine this with another challenge. Generally, though, pick fights with guards as you run around the city. Pick the fight with either a Hook and Run or a Hook and Throw to combine this challenge with the two challenges from the Thieves and Romani Guilds, respectively. NOTE -- If you refrain from killing your opponents, then your Templar Awareness will not rise. Respond to those NPC's that attack you with the Counter Steal to combine this challenge with a Thieves Guild one. Call Assassins on a target ----- 20 Target a highlighted guard with R1; then squeeze L2 to signal your Assassin recruits. Focus on rooftop guards to kill two birds (the guards and this challenge) with one stone. ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ B. Challenge Set 2 [ASGC2] Reward: Assassin Signal recharges at increased speed. -- As this is a highly valuable reward from a practical standpoint, I recommend an early focus on this pair of challenges. Use Arrow Storm ----- 15 Squeeze and hold L2 in the presence of enemies. (Note: Janissaries, Varangians, and Almogovars may only be wounded by this, depending upon the number of other NPC 'targets' the Assassin recruits must hit.) As a significant amount of time is required to let the Assassin Signals fully recharge and as it requires that you have at least six Assassin recruits not on a mission, I recommend using Arrow Storm immediately before visiting an pigeon coop or Assassins' Den for the Mediterranean Defense minigame. NOTE -- In Sequence 8, Memory 1, you receive an unlimited number of Assassins Signals, if you care to wait that long. I recommend against such a wait. Call your Assassins within a story mission ----- 5 You can call your Assassins both in core missions and in side missions. This will combine with the Set 1 challenges. ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ C. Challenge Set 3 [ASGC3] Reward: Unlocks the Assassin faction weapon. -- Altair's Sword (Damage: 4/5, Speed: 3/5, Deflect: 4/5) NOTE -- This is not the best weapon of the game as is the case in Assassin's Creed: Brotherhood. Yusuf's Turkish Kijil (the reward for completing the Master Assassin mission 'The Deacon Part 1') is the best, followed by the Almogovar Axe (the reward for completing the Master Assassin mission 'The Champion Part 1'). Recruit Assassins ----- 12 Fill up all available slots in your local guild, and send one to an Assassins' Den in another city. Recruit a twelfth person to fill the now empty slot. NOTE-- If one or more recruits die, then those you recruit to replace them do count towards this challenge. Train recruits to the rank of Master Assassin ----- 7 Complete all 14 Master Assassin missions after assigning a Level 10 Assassin to each of Constantinople's 7 Assassin dens. This requires that each of these seven recruits earns 15,500 XP from missions first. You must finish Sequence 2 for one of the seven. Successfully perform a Den Defense --- 3 Den Defenses generally will be instigated when your Templar Awareness meter reaches 100%. NOTE -- Once all 7 Assassin dens have a Level 15 Master Assassin, their dens can no longer be attacked, ending this minigame. If you had not fulfilled this challenge for any reason, then you are given full credit nonetheless. NOTE -- Repeating Sequence 2, Memory 6 counts towards this challenge. This is helpful if you are poor at the den defense minigame. (*Credit: I learned this from 'Jim,' with much thanks for the tip.*) ============================================================================== IV. Mercenaries Guild Challenges [MCGC] A. Challenge Set 1 [MCGC1] Reward: Cost of hiring Mercenaries decreases. -- The price drops by one-half from 150 akce to 75 akce. Use Mercenaries on guards ----- 10 If you are especially frugal, you can satisfy this with the services of a single group of mercenaries, for each segment of battle into which you send them counts separately. (This saves you 1350 akce.) Call your Assassin recruits during the fights to combine this with the Assassin Guild, Set 1 challenges. Destroy scaffold by throwing someone into it ----- 5 Scaffolds are not as plentiful along guards' routes as they seemed to be in Assassin's Creed: Brotherhood, so you will need to lure guards near one. Good places include among the first streets south of the docks in Imperial North and Bayezid North. I suggest getting their attention using the Hook and Run to give you an ample head start, as well as contribute to fulfilling a Thieves Guild challenge. Stop just past the scaffolding, and immediately enter combat mode. Then, simply grab and throw an opponent. (Note: The stronger NPC's are resistant to grab.) NOTE -- See FAQ section, Question #3. Kill an enemy using a thrown weapon ----- 5 This requires a heavy weapon, which you can purchase from Blacksmiths starting in Sequence 2 after purchasing the right sheath from a Tailor, or you can get from picking up the dropped arms of Almogovars. Target an enemy, press and hold Square. Release to throw. If the weapon was your primary long blade, you can re-equip by picking it up, visiting the armory in Headquarters, or visiting a Blacksmith and selecting that weapon if you originally purchased the weapon from one. NOTE -- As this requires wind up time, which leaves Ezio vulnerable to attack, it is safest not to use this strategy while in active combat. Enter fights started by your Assassins (Set 1) and/or Mercenaries (above) with this method. ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ B. Challenge Set 2 [MCGC2] Rewards: Unlocks Mercenary Faction ability. -- Hired mercenaries act as bodyguards, keeping inquisitive guards and harassers away. Mercenaries Guild crest is awarded in Headquarters. Disarm and kill a guard with his own weapon ----- 5 If you remember to be in combat mode unarmed, this is simple. Kill a Byzantime Almogovar ----- 25 These axe-bearing, heavily armed guards become increasingly common as you progress through the sequences. The Master Assassin mission 'The Thespian Part 2' has an abundance of Almogovars. Perform a Hook and Throw ----- 10 Run towards an enemy and tap Circle as you approach. I recommend combining this with Assassin's Guild, Set 1's challenge to call Assassin recruits into combat with you since you automatically enter combat upon completion of this move. ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ C. Challenge Set 3 [MCGC3] Reward: Unlocks Mercenary Faction weapon. -- Broadsword (Damage: 5/5, Speed: 4/5, Deflect: 4/5) Perform a Double Assassination ----- 10 Assassinations from above or by walking between two guards count. Kill 5 Guards in under 10 seconds in melee ----- 1 Kills for the next challenge will satisfy this challenge. Perform a combo kill streak of at least 5 kills ----- 10 This must be completed in the earlier sequences, ideally Sequence 2-4, for by Sequence 8, every set of guards contains at least one Janissary. Janissaries require three hits in combo kills or counter-kills to dispatch them, thus ruining your kill streak. To get five or more guards in one place, use Hook and Run to collect guards to chase after you before starting combat. Sequence 4, Memory 3 is a good mission to repeat until you satisfy this challenge. NOTES -- Personally, I find it easier to maintain kill streaks using a short blade. The special animation is quicker, making it less likely that an off-screen NPC will attack you, requiring a counter, or that a guard will grab you from behind. Also, remember the cliché "better safe than sorry." Do not stop after your fifth kill if more NPC's are around in case you miscounted. Last, this is the one time when you do not want to call your Assassin Recruits into battle with you as they have a tendency to kill your next target in the streaks. Kill an Ottoman Janissary ----- 25 Janissaries are highly recognizable for their masks. If you wish to satisfy this earlier in the game, you can find 2-4 Janissaries stationed in the westernmost courtyard of the Galata district (number depending upon how early in the game you seek them), directly west from a Tailor. Four Janissaries will guard two treasure chests along the docks of Galata toward the east. Most importantly, the Janissaries have a camp in Constantine North, just east of Fatih Mosque, if you are an expert in combat. NOTE -- During Sequence 2, not all of the NPC's in the camp will be Janissaries, which can make the combat a little easier for novices. ============================================================================== V. Romanies Guild Challenges [RMGC] A. Challenge Set 1 [RMGC1] Reward: Cost of hiring Romanies decreases. -- The price drops by one- half from 150 akce to 75 akce. Use Romanies on guards ----- 10 As few mission require using Romanies as decoys, hire Romanies as you come across them, and send them to distract random patrolling guards until you satisfy this challenge. Evade using stealth (crowd/hiding spots) ----- 10 To those who find combat an easier way to deal with enemy awareness, this challenge is annoying. Hiding spots are not as plentiful. The average building is taller, requiring more climbing time, and crossing district borders means you lose the guards rather easily. Use a Tactical Bomb (e.g., Caltrops) to combine this with a Set 2 challenge if you make it into a hide spot before you lose your pursuers. Kill guards using the crossbow without being detected ----- 20 Rooftop guards are the easiest targets, followed by targets that you shoot from rooftops. ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ B. Challenge Set 2 [RMGC2] Rewards: Unlocks Romani Faction ability. -- Romanies that peel away from Ezio when you walk too near will poison those guards. Romanies Guild crest is awarded in the Headquarters. Use Tactical Bombs to escape guards ----- 10 The best bombs to use are either Caltrop Bomb or Smoke Screen (active ingredient: phosphorous). I recommend entering a hide spot or blending with a group of citizens to combine this challenge with one in Set 1. Kill a Stalker without getting stabbed ----- 5 Stalkers attack randomly when you are on street level, but they are especially prevalent when your Templar Awareness meter is full. Press Square to kill them quickly after the animation begins. NOTE -- Loot Stalkers' corpses for a rich haul (over 1400 akce). Kill guards using poison ----- 15 The Datura Bomb is the easiest manner, if you find guards separated from civilians, such as during missions, but as Fast Poison is available early in the game (Sequence 2), traditional darts or the superfluous poison blade works, too. ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ C. Challenge Set 3 [RMGC3] Reward: Unlocks Romani Faction weapon. -- Romani Stiletto (Damage: 5/5, Speed: 3/5, Deflect: 4/5) Kill guards using bombs without being spotted ----- 20 The Piri Reis missions will help get through a significant amount of this challenge, but any bomb thrown from a distance or from a rooftop will suffice. Assassinate a guard from behind ----- 10 Rooftop guards are especially easy targets, but there is no need to ever focus on this challenge. Assassinate a guard from a blend spot ----- 5 Few guards' patrol routes travel close to haystacks, but more pass by benches. Use Eagle Sense to identify likely spots. To help this challenge along, throw a Diversion Bomb, such as a Cherry Bomb (active ingredient: sulfur) or Smoke Decoy (active ingredient: Salt of Petra), at a haystack when guards are in the area. Enter the haystack, and kill the guard(s) who come to investigate. Kill 3 enemies dazed by a single smoke bomb before it dissipates ----- 1 Make the strongest Smoke Screen bomb (active ingredient: phosphorous) using Impact Shells and British Gunpowder. Throw it at the feet of a group of guards, and with Eagle Vision activated, enter the smoke. To ensure you have enough time, aim for a double assassination for your first kill, which will combine this with a Mercenaries Guild, Set 3 challenge. ============================================================================== VI. Thieves Guild Challenges [TVGC] A. Challenge Set 1 [TVGC1] Reward: Cost of hiring the Thief Faction decreases. -- The cost drops by one-half from 150 akce to 75 akce. Use Thieves on guards ----- 10 A few missions require the use of thieves, but not nearly enough to satisfy this challenge. Hire thieves as you pass them, directing them to lure away whichever set of guards you next come across. NOTE -- If you send your Thieves towards a solitary rooftop guard, after the NPC is dispatched, perhaps by you using the crossbow to speed things along, you retain the Thieves. Frugal players can save akce in this manner. Sprint uninterrupted for 300 meters ------ 1 The creek that separates Constantine North and South is the best location. It does not have an open distance of 300 meters, so careful turns are necessary. Perform a Hook and Run ----- 15 To quickly fulfill this challenge, use the same set of guards, running back and forth through them. If you wait longer, some later missions in Sequences 7 and 8 require you to bypass guards, but this is best combined with Assassins Guild, Set 1 challenges and/or collecting guards for Mercenaries Guild, Set 3 combo-kill challenge. ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ B. Challenge Set 2 [TVGC2] Rewards: Unlocks the Thief Faction ability. -- Hired thieves will steal from the civilians and the dead bodies they pass as they follow Ezio. Thieves Guild crest is awarded in the Headquarters. Perform a Leap of Faith ----- 40 Normal gameplay will satisfy this challenge. Climb a total distance of 1 km ----- 1 Normal gameplay will also satisfy this challenge. If you wish to speed things along, climb Galata Tower a couple times. Steal money with a Counter Steal ----- 250 akce In combat, before you use Counter-Kill for Mercenary Guild, Set 3 or call Assassin recruits from Assassins Guild, Set 1, do a Counter Steal. (Press Triangle when you would normally press Square for a Counter Kill.) This is easy if you remember to do it, and it will require but six through ten victims to collect the total necessary. ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ C. Challenge Set 3 [TVGC3] Reward: Unlocks the Thief Faction weapon. -- Ottoman Mace (Damage: 4/5; Speed: 4/5; Deflect: 2/5) Perform a dive of at least 30 meters ----- 1 The tower ramparts along the south of Imperial South are ideal. Press X immediately after jumping. Kill a guard using throwing knives ----- 25 Throwing knives are my weapon of choice for dispatching rooftop guards, so there is no need to consciously focus on this challenge. Holding Triangle to throw multiple knives is a great way to enter the combat to recruit new Assassins. Perform an air assassination on guards from a beam ----- 5 Use Eagle Sense to identify guards' routes. Perch along a beam over a street, and air assassinate the guards when them come along. Aim for a double assassination to combine this with a Mercenaries Guild, Set 3 challenge. Perform a zipline assassination ----- 10 Opportunities for these are not as prevalent as you might think. Some ziplines in Constantine South, east-southeast of the Romanies Guild headquarters, and in eastern and central Galata provide a couple opportunities to accrue kills. Use Eagle Sense to confirm that guards' routes are beneath a zipline or, more commonly, are at the end of a zipline. Three memories (Sequence 2, Memories 5 and 7; Sequence 5, Memory 3) include a zipline assassination as a part of the mission. ============================================================================== VII. Bomb Challenges [PRBC] NOTE -- Doing the Piri Reis missions, available after Sequence 3, Memory 4, will help you along these challenges well. A. Challenge Set 1 [PRBC1] Reward: Extra bomb ingredients found within Dens. Stick a bomb on a guard ----- 10 Use bombs made with the Sticky Pouch. Any type of bomb works. Kill a mission target with a bomb ----- 1 The Piri Reis missions require this. Distract a guard using bombs ----- 20 Use Diversion bombs as you come across guards as you seek the Treasure Chests, et al. The number is distracted guards, not bombs. Kill 5 guards with a single bomb ----- 1 You want to use a Splinter Bomb (active ingredient: shrapnel) with an Impact Shell and British Gunpowder. The only challenge to this is finding a place with 5 guards unaware of your presence so that you can safely deploy a bomb. Find the Bank in the Bayezid North district, which is southwest of the westernmost ferry terminal. Two guard routes overlap but a few meters west of the Bank. A little patience for the guards' routes to synchronize, and you will have 8 guards. Other spots include along the docks of the Bayezid North and Imperial North districts. Sets of guards congregate near the gates, and patrolling guards will periodically pass nearby. Also, in the Piri Reis mission 'Sticky Situations,' if you throw the bomb too soon for the target to reach the other two targets, turn around and run, and U-turn to your right up the slope. Carefully peer over the edge, and throw a second sticky bomb at the surviving target(s). The guards will have come to investigate the corpse(s) of the first bomb, making a condensed collection of guards. Kill guards with Tripwire bombs ----- 20 You need two types of bombs: in your Lethal pouch, Datura bombs with a Tripwire shell and at least Arabic Gunpowder, and in your Tactical pouch, Smoke Screen (active ingredient: phosphorous) bombs with Impact Shells and ideally British Gunpowder. Distract a set of 4 guards with the Tactical bomb, and run into their midst, setting the Datura bomb. As the NPC's will set off this bomb immediately, flee the immediate area to escape the poison. You will have few, if any, civilian casualties with this method. NOTES -- First, thank you to 'Kat' for noticing that this challenge had not been included in version 1.00. Second, thank you to 'FaithnTubz' for the above strategy, which is vastly easier and quicker than my original. ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ B. Challenge Set 2 [PRBC2] Reward: Bomb capacity upgrade. -- Ezio can now carry four of each bomb type. Craft a bomb with every shell type ----- 1 Make any type of bomb with a Fuse Shell, Impact Shell, Trip Wire, and Sticky Pouch. Using them is not necessary. To complete and log the 'crafting,' you must exit the crafting station, however briefly. Use a bomb ----- 50 Normal gameplay, the Piri Reis missions, and the Set 1 challenges will satisfy this challenge easily. Also, there are 31 hidden wells, which can be opened as hide spots only with a bomb. Kill a guard incapacitated by a bomb ----- 25 The easiest place is to repeat the Master Assassin mission 'The Champion Part 2' as it essentially requires using Stink Bombs or Smoke Bombs for the Full Synchronization requirement. Craft one bomb of each effect type ----- 1 There are ten types of effects (3 Lethal, 3 Tactical, 4 Diversion). A little time at a crafting table will easily satisfy this challenge. Again, to officially craft a bomb, you must exit the station after the production. Use every bomb effect at least twice ----- 1 The Piri Reis missions will satisfy one-half of these and get you halfway through another two of the effects. The Blood Bomb (active ingredient: lamb's blood), the Stink Bomb (active ingredient: skunk oil), and the Gold Bomb (active ingredient: pyrite coins) must still be used twice. The Splinter Bomb (active ingredient: shrapnel) and the Thunder Bomb (active ingredient: coal dust) must be used once more, which you could do by repeating the 'Sticky Situations' and 'Thunder' missions if you are so inclined. ============================================================================== VIII. FAQ [FAQS] 1. Can Altair's memories be used to count towards completing these challenges? Answer: I have received confirmation, with thanks to one 'Anthony,' that indeed only Ezio's memories count. That is, no, Altair's memories cannot be used to satisfy the challenges. 2. Can Ezio's memories in Sequence 7 count towards these challenges? Answer: I have received confirmation, with thanks to another 'Anthony,' that only in Constantinople can the Guild challenges be completed. 3. Must you destroy a scaffold for Mercenaries Guild Challenge, Set 1 using a guard or other enemy? Answer: No, an answer given to me first by 'Daniel.' That is, yes, you can use civilians, but killing civilians will lead to desynchronization. Moreover, while not using Byzantine or Ottoman NPC's may be easier, it is certainly cheating against the 'spirit' of the challenge. I report it here only for the sake of completeness, but I repudiate it as a legitimate strategy. There is a grey area. An old acquaintance appears first in Sequence 4, Memory 3 and shortly thereafter in Constantine South as a figure that is neither an NPC nor a guard in the strictest sense. He re-spawns if you kill him, so you could repeatedly throw this character into scaffolding to satisfy this challenge. Whether or not this breaks the 'spirit of the challenge' is open to interpretation, as you are not actually supposed to kill this character. (You beat him up to unlock a Trophy/Achievement.) (**Credit: Another 'Jim' discovered this, and I thank him for the insight.**) ==============================================================================
