I haven't had a freezing problem with it yet. Then again, I installed it to my hard-drive to make sure it ran nice and smooth online and offline. So your copy will actually just freeze up randomly, Jose? That sucks, man =(
It's not a disc problem (I already trade 3 new disc copies and it still happens) or Xbox problem (it's happening from the old arcade to the new Gears of War 3 Xbox's), it's a gamertag problem (All other profiles work fine except for mines). I did everything, install/uninstall, clear cache, delete and restore your gamertag and the same freezing problem happens,
It doesn't freeze up randomly, it freezes everytime I try to play ANY mode, it would freeze on the loading screen, and yet I could watch my rank, ribbons, and medals without any problems; speaking of rank, all of my rank, ribbons, medals, and characters have been reset except for my campaing items. The game was working fine for one week and then this bug happened.
If you want a more accurate description, here's a video on what happens:
I also don't plan on buying their season pass, or any of their products if they don't get this fixed.
