I got GRAW2 last week, put in my Xbox 360, and I couldn't play it because it constantly freezes (no graphical glitches, it simply freezes and my 360 won't respond anymore) in different zones: sometimes at the starting jeep sequence, sometimes in different points of the tutorial mission, and if I skip it, then it freezes in the next helicopters sequence, every time in different points. Heck, it even freezes if I put up the pause menu and stay there some while!
I've tried everything: clearing the disk cache, deleting the savegame, and playing without the hard disk (no memory card). Nothing worked, and it isn't a a disk problem because the I gave it to a friend of mine and it works perfectly on his 360. Add to this that the multiplayer part works flawlessy on my console: I came to the conclusion that the campaign executable has some kind of "compatibility" problem with my console. Obviously, my 360 works flawlessly with every other game: RS:Vegas, Crackdown, GOW, Viva Pinata and so on, so I tend to exclude it's an hardware problem.
I tried to search on Ubisoft forums, and comes out that many other people has the same exact problem!
Look here. Has someone here experienced the same issue, and why if many people is having it no site has reported about the fact?
EDIT: Some people misunderstood the problem, so it needs to be written more clearly:
THIS ISN'T A CONSOLE BRICKING ISSUE. This is different than when you put a game in the console and it suddenly breaks with the three rings of death. In this case, the game simply refuses to work correctly, but after that the 360 keeps working perfectly with all other games.
