I was a bit disappointed that the DLC for this had no real single player content (sticking a timer on each SP level doesn't really count) although, to be fair to them, I had wondered how they'd slot SP content in without buggering up the story they've already finished telling in the main campaign. I really should get round to playing the new co-op levels, although that would involve buying a new PS3 controller and goading Mrs Bamba into getting comfortable with the controls again. I actually played the majority of the original co-op levels myself by jusy swapping between the two pads as required. Obviously you're not going to win any speed awards that way but it's surprising how many of the levels can be knocked off relatively easily that way; I think there were only a few levels where simultaneous actions were genuinely required from both players.
