Since a lot of good ones have been mentioned already I'll give the casual CoD: Modern Warfare comment, think it was 4(?).
Campaign was pretty exciting (well general 'story' aside
) back then - the newer ones all borough from that, so if you haven't played these I'd recommend MW.
The Return to Castle Wolfenstein is supposed to be pretty solid, may give it a look, despite its age, if you haven't already.
