I'm talking about the Xbox "factory" demo level. I killed all the Nazis I could find, found the "Venom" book, then couldn't figure out what to do! There was a Nazi who had been shooting at me and ran away, closing the door behind him, but I couldn't get to the bombed out floor that he was on, and slowly whittled my health away trying to jump to that floor and falling...finally, having begun with nearly full health, I ended up dying from all the falls - @#&!$%! Am I supposed to get to the floor where the Nazi ran away? If so - HOW?
