I bought Brink used and it would freeze about 5 min. into a match campaign,multi,private,etc. Then i bought it brand new and its still having freezing issues every 5 min. or so i don't know why other games work fine Dead Space 2 works Dead rising 2 works. I just dont know what to do there isnt a visible scratch to be seen either. I need help to figure this one out.

Uuuh... That's usually a laser problem or something. Couldn't tell ya.
Maybe your console didn't like the reviews Brink got.

If your Xbox, install it to hardrive, it really helped with that problem for me. (Still happens occasionally.)
