Anyone else playing Gun Bros on iOS? Or any other Game Center game?

[Tooker]

Say, is anyone else playing Gun Bros?  It's an iOS double-stick shooter.  I ask, because if you are, we should be Game Center friends. :)  If your friends are playing the game, you can have their character join as your second player, rather than the weak AI character.  My name's Tooker there, too.
