What are some good co-op games for PS3?

My friend and Iare trying to get a new game that has kick ass co-op. An action game or a RPG. I have Borderlands on the 360 so I dont want to get it again. What games y'all fellow gamers recommend?

i believe sacred 2 has a co-op mode (dont quote me on that though) its a big looting adventure/rpg. i like wipeout HD but thats futuristic racing.

Resistance Fall of man (only offline splitscreen co-op) is lots of fun. Resistance 2 is supposed to be good for co-op also. Resident evil 5 offline and online co-op. Call of duty world at war has co-op.

rainbow 6 vegas 2 is very fun online.. plus i bet u could find it pretty cheap now

That should be all you need

new cod has a decent coop mode. resident evil 5 and resistance best coop games.

Modern Warfare 2

I would recommend that you use the recommendation thread.Post it there.
