The game against ... Ultra ended badly, the game can no longer load the backups after a few hours of co-op play. Forced to redo everything, finally want to start the coop is low as this bug happened 2 times in 2 nights with my playing partner. It goes without saying that this kind of mishap never happened to me on any another PS3 game.
It is a pity that, apart from that, the game would be rather pleasant. A solo see if it works better, but I'm not really seen some comments on the official forum of the game.
In conclusion, it's still a good deal, but much to consider before you buy any good figure with a buggy game to the bone.
