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 (2016 video game)
In a 2016 video documentary by Noclip's Danny O'Dwyer, Creative Director of "Doom (2016)" Hugo Martin described the "Hell on Earth" premise as: "It was like Robert Zemeckis. See "Contact", like, if this really happened. Now let's be clear: it was awesome. But it was more realistic. It was about the global impact of a Hellish invasion." The creative director of the "Doom 4" prototype, Kevin Cloud, said in the same interview, "As far as the upper-level creative direction, that was me driving that. And honestly, again, taking it in a direction I don't think the fans would have enjoyed."
