Doom is a first-person shooter video game series that was first released in 1993 by iD Software. Although it was not the first game to feature the first-person shooter mechanic, Doom was notorious in the early 90s for its revolutionary 3D graphics, action-packed violence, and networked multiplayer gaming capabilities. And although these features gained it some negative press, it was still a huge commercial success and is consequently considered one of the most important video game franchises of all time. So far there have been three games in the series, each with a series of expansion packs. The series was also adapted into a movie in 2005.

1. Doom (1993)
2. Doom II: Hell on Earth (1994)
3. The Ultimate Doom (1995)
4. Master Levels for Doom II (1995)
5. Final Doom (1996)
6. Doom 3: Resurrection of Evil (2004)
