Doom  1993

A significant upgrade over the wildly popular Wolfenstein 3D, Doom is one of the most recognized and groundbreaking games ever created. An unnamed space marine serving on Mars must save humanity when teleportation experiments allow evil creatures to overrun Mars and its moons, Phobos and Deimos. The HUD looks a lot like the HUD from Wolfenstein 3D, but Doom adds a third dimension to the level design, allowing for ramps and stairs, as well as enemies that can attack from above or below. Another new feature of the engine is destroyable objects, such as canisters that can be shot and detonated to hurt nearby enemies. In addition to health, the player also has an armor meter. Originally a trilogy, a commercial release called Ultimate DOOM added a fourth episode. Shareware v1.25 was a special demo created for Sybex. Doom was so popular that Microsoft developed a Windows 95 port to showcase Windows 95 as a gaming platform. There are 4 episodes in this game, with only the first episode playable in the shareware version.

Episode 1 - Knee-deep in the Dead
Episode 2 - The Shores of Hell
Episode 3 - Inferno
Episode 4 - Thy Flesh Consumed

Cheat Codes

idbehold# - When # is one of the letters below, this gives the powers of an item:
"R": Radiation shielding suit.
"I": Partial invisibility.
"V": Invulnerability.
"A": Computer area map.
"L": Light amplification visor.
"S": Berserk.
idchoppers - Gives the option to select the chainsaw.
idclev## - Warps to level E#M# or MAP##.
iddqd or idqd - Sets health to 100% and makes player immune to damage ("god mode", "degreelessness"). If the player is currently standing on or subsequently enters a damaging floor of type 11, the invulnerability effect is nullified. The invulnerable player can also be killed by a telefrag, and projectiles with extremely high damage ratings (such as from a DeHackEd modification) can also kill a player in god mode.
iddt - This cheat reveals information if used while in automap mode. First use: full automap (reveals unexplored areas, including invisible linedefs not shown by the computer area map powerup). Second use: full automap with items, monsters, players, obstacles, and decorations. Third use: the automap is restored to normal.
idfa - Grants full megaarmor protection (200%), all weapons, and full ammo.
idkfa - Grants full megaarmor protection (200%), all weapons, full ammo, and all the keys.
idmus## - Plays music from level MAP## in Doom, and E#M# in The Ultimate Doom. Using this cheat code will make the player change weapons in hand if the numbers pressed correspond to available weapons.
idmypos - Shows the player's coordinates and compass direction (note that these numbers are hexadecimal, and may require some practice to interpret quickly).
idspispopd - No clipping (the player can walk through walls, monsters, and obstacles, climb high ledges instantly, and pass through items and across all tagged linedefs with no effect).

Doom95

fhhall - Kills all monsters in the level, excepting lost souls. (Pain Elementals killed in this manner will still generate extra lost souls as normal).
fhshh - Monsters do not notice players unless they are hurt or hear a shot.
