Any Good fps games to buy?

Hey guys! I have a ps3 and I have played black ops, moh airborne, bc1, bc2 and MAG. Im good at black ops but sometimes im good at bc1 but sometimes i get spawn trapped. I bought Mag a week ago and im good at it but its soo hard and i keep getting spawn trapped. I borrowed bc2 from a friend and really enjoyed playing squad deathmatch and was good at it. MOH airborne is good but theres only like 30 people online a day. Do you know any other fps for ps3 I could buy? our help is greatly appreciated!
