apparently there's a level where you play on your own so Co-op kinda O.o
not everyone plays with friends I especially prefer playing on my own, if you are that desperate to play with others, you have a VERY deep online to keep you.

And why say "saviour" when it's blatant that the ps3 has no need for a saviour?
