I've been playing the game all afternoon and every now and again (in about 5 hours it's happened something like 7 times) the game will freeze up.
It occurs either when I die, or when i've finished the level and it's counting up my percentages, it will get through the first two, then on the third the game will hang, the animation is still playing, but no numbers appear, and all I can do is quit to dashboard.
When I die and it freezes though, nothing, I have to turn the console off.
And nobody better say my console is about to RRoD, it's literally only just arrived back from repair this morning, and if it's broken i'm going to flip my lid at MS this time, they already kept me waiting nearly 3 weeks for shipping labels due to a computer error. And I played 2 hours of RB without stopping so I'm hoping it's just wolfenstein. I remember Doom caused the console to crash sometimes if you try to quit the game.
