>>13227064There's a ton that I personally like, TF2 campaign is really hard to match it had no business being as good as it was:
CoD Mw2
BFBC2
EYE divine Cybermancy
Deus EX (original) HR but not the sequels
ARMA2 (it's more mil sim but it has cheesey voice acting and some ridiculous scripts if that's you thing, personal fave or mine)
Full Spectrum Warrior (not FPS more like Squad leader simulator but really interesting)
MoH: Warfighter
R6: Vegas 2 (interior close quarters stuff)
