10 Essential First-Person Shooter Campaigns You Must Play

9. Bioshock

Not everything in the FPS mould has to be a smorgasbord of explosions and "Hoo-rah!" dialogue. Instead, when those dials are turned back a notch, you get Bioshock; a game that occasionally revels in intense gunfights with intimidating enemies, but mainly focuses on establishing one of the greatest environments and atmospheres ever seen.

If you've somehow not played Bioshock (and man, what I wouldn't give to experience it again first time), know that a plane crash leads to a lighthouse, which leads to an underwater city of mystery, science fiction and philosophical pondering all rolled into one.

Bioshock's endgame twists are spectacular, but it's the feel of exploring the wondrous Rapture for the very first time, unlocking new weapons and uncovering precisely what happened before you arrived that'll truly stick with you.
