Development of Doom
The development of "Doom", a first-person shooter video game by id Software, began in November 1992 and continued until the game was released in December 1993. Seven people worked on "Doom", which is considered one of the most significant and influential titles in video game history. The initial development team was programmers John Carmack and John Romero, artists Adrian Carmack and Kevin Cloud, and designer Tom Hall; late in development Hall was replaced by Sandy Petersen and programmer Dave Taylor was added to the team. The music and sound effects were created by Bobby Prince.
First-person shooter
"Doom", released as shareware in 1993, refined "Wolfenstein 3D's" template by adding improved textures, variations in height (e.g., stairs the player's character could climb) and effects such as flickering lights and patches of total darkness, creating a more believable 3D environment than "Wolfenstein 3D's" more monotonous and simplistic levels. "Doom" allowed competitive matches between multiple players, termed "deathmatches," and the game was responsible for the word's subsequent entry into the video gaming lexicon. According to creator John Romero, the game's deathmatch concept was inspired by the competitive multiplayer of fighting games. "Doom" became so popular that its multiplayer features began to cause problems for companies whose networks were used to play the game.
