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.
Video game controversies
On 20 April 1999, 18-year-old Eric Harris and 17-year-old Dylan Klebold killed 12 students, a teacher, and themselves in the Columbine High School massacre. The two were allegedly obsessed with the video game "Doom". Harris also created WADs for the game, and created a large mod named "Tier" which he called his "life's work". Contrary to rumor, however, neither student had made a "Doom" level mimicking the school's layout, and there is no evidence the pair practiced the massacre in "Doom".
