Quake III is all you need for crazy action :)
If you're looking for a half decent story, then I recommend Soldier of Fortune. it's got terrorists before terrorists were vogue :P
These are both oldies, so you might have trouble finding them...
I agree with the people who said HL2 is good. Although avoid anything particularly modern - seems that these days the FPS genre has been diluted into a watery piss that isn't very nice.
