when i try connect to a match,i dont seem to get up any servers at all.why is that or do i simply need to let it run its search?

The multiplayer is royally messed up at this point. All honesty, you're not missing much. It's nothing like the original Crysis. Think some bastard spawn of Halo and Counterstrike without as much thought or time put into either, no vehicles, and you've got what it's like.
