I'm telling you what...I can't find any actionable levers or panels on xbox. I've been killing walking armor for about an hour and I can't get old Raze down to more than 50%. I've stood in his chamber (he heals with me in there). If I could just find a way to disable the generator for a minute I could kill him. Otherwise, I guess, I'll have to go get firewall etc., as SoulWing suggests.
