On the discussion of co-op...
Co-Op is NOT a bad thing in and of itself. But lately, dev's seem to thing that just adding Co-Op play means they got a sequel :/ Look at Lost Planet 2. Same game, same issues, a few minor changes, but it's okay... because it's Left 4 Dead with mechs and giant bugs. People will play that, and less work is done.
If you ask me, Splinter Cell: Chaos Theory is the way Co-Op should be. Have a separate campaign mode specifically for the Co-Op, with a pair/group designed to compliment each others skills.
So if Catwomen means theres guna be Co-Op, I just hope it's not forced into the campaign mode. Hoping I get to play as her though. Like fast fighting better then Batman's stuff.
