Did he die? Where did he go? Last I remember about him is that there were bombs going off around his house, then he built a new computer, and disappeared.
He's probably rallying his own mercanaires to take over his land. It's not hard to find a AK-47 laying around somewhere, its like trying to find trash in america.
My guess is he's sitting in his bunker and his mercs are watching for jihads in the base.
