Looking for a FPS with a good single player campaign. Suggestions?

Well It depends what system you are talking about?

PS3: Killzone 3 (I would reccomend this the most)

Xbox 360: Halo Reach

PC: Crysis 2

I would say Killzone 3 or Reach. There really aren't any good new games for PC any more FPS are much better on PS3 and Xbox 360 these days.
