for me it was in the lab level, with the gunship, I had killed the gunners and the chopper turned away, so I thought it was defeated and was looking for a way out, then I saw the shadow of some guy with a big gun on the roof cast on the wall in front of me...
Guy who posted this thread, that sounds awesome... that's pretty much what Crysis 2 is all about. Man, you're not the brother of OP? Just 'cause you **** like he.
