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.

According to Stratton and Martin, movement is the game's most important pillar. To help keep movement fast, weapon reloading was excluded and levels were designed to discourage players from hiding. On January 25, Stratton confirmed the game's feature of non-linear exploration and stated that combat is the game's focus and that the difficulty of the game was raised with the aim of creating an ultimate first-person shooter. On March 31, 2016, the release date of the "Doom" beta, a cinematic trailer directed by Joe Kosinski was created to evoke the game's three core pillars: incessant combat, terrifying demons, and powerful guns.
