If you read the threads in this sub-forum, you'll notice that most of the complaints revolve around the game glitching and freezing at certain points. Almost all the time at a cutscene. I suspect it's a problem with the game's auto save feature. I experienced a similar problem with UC3, but luckily got past it. My system has no issues with any other games. I don't understand why the multiplayer constantly gets patched, but nothing for the single player despite the widespread problems and complaints.
Since a lot of people are probably getting the game for Christmas, now is the perfect time to fix this. Please stop burying your heads in the sand Naughty Dog. Acknowledge the problem and work on fixing it.
Have to agree with u on all u have said brilliant game but a lot of the time i get frustrated with one bug or another often having to shut my ps3 down cus it jams the whole machine and i lose the will to start it all up again to continue.Im lucky enough to own both ellie edition and joel edition this happends on both and the disc is scratch free.Luckily for me though it does let me resume my game and i get to carry on my playthrough..well untill it happends on a different part of the game,although not always.
