Anyone have a suggestion for an FPS with a good single player campaign/storyline?

Assuming you've already played Half-Life 2 and other high profile games of that ilk (F.E.A.R, Far Cry, Prey, etc) one game that I think was kinda underrated (I never really hear about it, at least) is Tribes: Vengeance. The story is told for a few different perspectives and, while I don't recall the specifics, I remember it being pretty good and more than the standard fare. The game play gets a bit repetitive, IIRC, but overall I really enjoyed it. Also, I believe there was a good multi player component too but all I ever played was the single player.
