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.
Duke Nukem (character)
Duke Nukem was initially created in 1987 by chief programmer Todd Replogle of Apogee Software (now 3D Realms) as the protagonist for the video game he was designing titled "Metal Future," which was set in the then-near future of "one decade later from now" in 1997. After hearing the character's name, producer and founder of Apogee, Scott Miller, suggested the game should have the same name, and he helped design the character. Artwork was produced by George Broussard, Allen H. Blum III, and Jim Norwood. Duke was not voiced, but spoke through on-screen text.
