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.

Over spring and summer of 1993, Carmack worked on improving the graphics engine of the game. After Romero's level designs started to cause problems with the engine, he researched and began to use binary space partitioning to quickly select the portion of a level that the player could see at any given time. Additionally, in March 1993, the company had to stop work on the game while the team spent three weeks building a Super Nintendo Entertainment System port of "Wolfenstein 3D", after the contractor who had agreed to do the port proved to have made no progress. Taylor, along with programming other features into the game, added cheat codes; some, such as 'idspispopd', were based on ideas their fans had come up with while eagerly awaiting the game. By fall, the game was nearing completion, with players eager to see it, spurred on by a leaked press demo. John Carmack began to work on the multiplayer component of the game; within two weeks he had two computers playing the same game over the internal office network. Soon, the office was playing four-player Deathmatch games.
