I got it for PS3, it's ok. Im not too deep into video games so I couldn't give an in depth review. I bought it for my son, he said its hard, but he's 9 so I don't know. I'm more into the Ghost Recon, Rainbow six type stories, not into the alien stuff really.
I don't really like the ps3 anyways I stick to the 360. For some reason all the games we have for the ps3 look really dull to me. We have Resistance,Def Jam Icon,Call of Duty, and Need for Speed. They all look this way
