I just got the game a few days ago and playing the campaign. Right after I hand over the Celerium to Briggs, the screen goes pitch black and I can't do anything. I've restarted the campaign endless of times, and does the exact same thing at the exact same moment after Briggs gets the Celerium; black screen.
I tried deleting cache, cleaning the disk, installing the game on my Xbox HD, nothing helps. Before exchanging it for another copy (which I'm not sure would solve the situation), is there anything else I could try to fix the problem. I have an older Xbox 360 Elite, I think from 2009 or so, with 120GB. I'm thinking perhaps the older console may be the problem, but I'm thinking the game was tested on all Xbox versions before being released, at least I hope so. BTW, other games work fine on my console, no problems at all.
Any help would be appreciated, thanks!
