Doom
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Doom is a violent first-person shooter computer game made by iD software in 1993.
It is one of the first games to use 3 dimensional levels. The "trick" people making the game used is that the levels are first shaped from above, then the game uses some information included within it to show a final "3D" view. The bad thing about the system is that levels cannot have one room over another, the same way you cannot draw something above what you have already drawn without getting confused later.
The game is about killing demons and zombies. Doom has traps that will hurt you and sometimes make you die and fall to the ground.
Doom was also the first game with multiplayer deathmatch.
The game was coded primarily in a computer language called C using John Carmack's advanced texture mapping technology.
