I am looking for something new to play, Preferably an FPS, but would prefer something that has Co-Op as well.

ones i dont want-

Any Call of Duty
KillZone
BFBC2 (already have)
Medal Of Honor

I would say Brink, but it's a letdown and not worth $60 in its current state.
I would also say MAG, but god knows its current state of affairs.
Maybe Resistance 2?

wait, i was thinking of Brink, i mean it looked interesting, but i would want to wait for the price to decrease, maybe Ebay

I realize you have it on your do not want list, but Killzone 3 is just about the best you'll get when it comes to good multiplayer. :wub:

Brink actually falls short of decent. You're better off playing Team Fortress 2. Left 4 Dead 2 is pretty fun as well.

What? I am only thinking of Resistance 2 or Metal Gear Online maybe.

Super Street Fighter 4

Black Ops

Uncharted 2. It's third person but one of the best shooters I've played.

Perhaps Rainbow 6 - Vegas 2?

You might like resistance, the third ones coming out soon. And like someone else here said, even know it's on your don't want list, Killzone 3 is amazing. Great story, great multiplayer and if you have a clan/team going it gets alot better.
