Notes: The "G" column shows the "Gamerscore" points for unlocking Achievements.
Achievements are only unlocked in Single-player games, except for DESTROYER and
ROOKIE, which are unlockable only in Deathmatch-mode games over Xbox Live.
In general, unlocks only occur after players exit a map or complete an Episode.
Skill 1 ("Difficulty 1") is "I'm too young to die!", Skill 2 is "Hey, not too
rough!", Skill 3 is "Hurt me plenty!", Skill 4 is "Ultra-Violence", Skill 5 is
"Nightmare".
Note that Lost Souls ("flying skulls") are not counted when computing the KILLS
score.  As such, the CLEAN SLATE Achievement can be unlocked on any map even if
Lost Souls remain when the player exits.
Unlocking the CLEAN SLATE Achievement can also unlock a "Marine" picture, which
can be used when customizing Player Profiles.  (This picture unlocks if "KILLS
100%" is attained on any map at any Skill.)
In order for "Frags" to be counted for the DESTROYER or ROOKIE Achievement, a
Deathmatch game must reach a Fraglimit or Timelimit, and end by displaying the
Tally Screen.  (Frags are not counted for a Deathmatch player unless the Tally
Screen at the end of the match is displayed for that player.)
For the EPISODE and RAMPAGE Achievements, it is not necessary to find or exit
any Secret maps (each Episode has eight normal maps and one Secret map, which
is accessible via a second, hidden exit on one of the normal maps).  For a list
of maps and their interconnections access: http://classicdoom.com/doomexit.htm
For the HOARDER Achievement, "ITEMS" include only Berserk Packs, Blur Artifacts
(also called Partial Invisibility), Computer Maps (also called Computer Area
Map), Health Potions (blue bottle, also called Health Bonus), Invulnerability
Spheres (green sphere), Light Amplification Visors, Soul Spheres (blue sphere,
also called Supercharge), and Spiritual Armor (green helmet, also called Armor
Bonus).  All other objects in the game can be ignored.
Note that unlocking the NIGHTMARE Achievement also unlocks a "Demon" picture,
which can be used when customizing Player Profiles.
To unlock the SCOUT Achievement a player must step onto any horizontal surface
that is flagged as a score-affecting secret area.  For more information on
