I hopped back in a few weeks ago, played about thirty hours, and then haven't picked it up since. My brother has recently gotten it, but for some reason the PS3 version seems to be freezing every time he goes underwater, so he's treading very carefully so as to avoid going underwater.
So, it seems like a lot of people are getting this itch at the same time.
Tell him to delete the update data and reinstall it. That will fix the water-glitch. Should be under "game utilities" or something like that.
I did. Hardhead won't do it because he'll have to wait for it to redownload.
Bah. It's only a few minute download! He needs to learn a thing or two about patience.
