I have an original 60 gb ( with a 320 upgrade). Game loaded ok and plyed well in offline mode. again- in online mode the game will freeze on elevators and opening and closing of doors. (at a progress saving point. All of my other ps3 consoles (slim,superslim, and the new 500gb white- will freeze at the same types of points- just not necessasarily on the same level Sometimes deleteing the GAME DATA, game save , and reinstalling everything( copied save files) sometimes- but not always- i can get another level or so in. I WILL NOT even attempt to try a co-op level again until there is a patch. I have 4 ps3's and 4 different usernames all at about 80% completion new game plus. can't do any co-op missions on any console. That is a lot of hours invested in this game so far. as much as I have loved every deadspace game it is just not worth the aggravation to play this anymore. I will keep checking for news of an update but until then it back to mass effect 3 or burnout paradise. Good luck to all.
