Doom (1993 video game)
Doom (typeset as DOOM in official documents and stylized as DooM in other media) is a 1993 first-person shooter (FPS) video game by id Software. It is considered one of the most significant and influential titles in video game history, for having helped to pioneer the now-ubiquitous first-person shooter. The original game was divided into three nine-level episodes and was distributed via shareware and mail order. The Ultimate Doom, an updated release of the original game featuring a fourth episode, was released in 1995 and sold at retail.

"Doom" was influential and dozens of new first-person shooter titles appeared following "Doom" release, and they were often referred to as ""Doom" clones" rather than "first-person shooters". The term ""Doom" clone" was used to describe the style of gameplay in "Doom"-like games. While the term was initially popular, it was, after 1996, gradually replaced by "first-person shooter", and the phrase "first-person shooter" had firmly superseded ""Doom" clone" around 1998. Some of these were certainly "clones", hastily assembled and quickly forgotten, while others explored new grounds of the genre and were highly acclaimed. Many of the games closely imitated features in "Doom" such as the selection of weapons and cheat codes. "Doom" principal rivals were Apogee's "Rise of the Triad" and Looking Glass Studios' "System Shock". The popularity of "Star Wars"-themed WADs is rumored to have been the factor that prompted LucasArts to create their first-person shooter "Dark Forces".
