Doom, a first-person shooter, casts players in the role of an unnamed space marine on Mars who must fight demonic forces released by a corrupt corporation. A near-constant stream of blood and gore, as well as frequent swearing, accompany Doom's battle sequences. Plus, expect satanic imagery and voyages into hell. Gamers use chain saws, guns, and their fists to blow up or decapitate enemies or to rip them to pieces in the game's extreme, action-movie-style firefights.
Alternate shooters: Ratchet and Clank (age 10+), Destiny: Rise of Iron (15+).
