Disc is scratched but if my nuketown was like that i wouldnt be complaining :p

Happened to me on Die Rise after hosting 8 man just before they patched it.

Sorry to break it to you, but unless your lucky, your xbox GPU is about to go poof.

i played die rise after it and everything was normal thou

It's really just a bug actually. Nothing really special, but check for any scratches or errors with your Xbox.

Not too sure if i was just unlucky, but heres what happened:

I hosted a 8 man die rise, and getting on in the game a bit, around round 14, this started happening, and then my xbox started lagging sometimes like when it crashes, but managing to come back to life again after a few seconds.

a week later, dead, opened it up, gpu had black dust all over it, so i assume thats what gave up

That looks way better than what happened to me, my disc got scratched and the result was that half the time the textures would become really lose their resolution until they were blurs and a lot of things turned green and everyone was bald

I tried watching thru theatre but it didn't record for some reason

It has to be your disc or it is just a lag or bug so you should be fine just make sure its not just your disc though
