I have it for the 360 but there are usually only a session or two in the game list yet in Survivors, one of the most crap, unbalanced, bs game mode ever, has the bulk of players in it. Ridiculous I say. I was thinking of getting it for the ps3 as well. :)
I love thePredator mode, its easily my favourite mode of the 3. The only problem I have with it is when your being revived or your reviving someone, the second the you finish you can be mowed down by the tackle attack, its so annoying, it needs like a 3 second invincibility period after reviving or something.
