I just finished the prologue, where you escape from the Nazi torture facility after your "brother" is killed, raced back to the farmhouse, and saved the girl. The middle-aged dude I was traveling with turned to the door and shot the lock off. But here is the wierd part: He wasn't holding a gun. He made the motions with his hand for squeezing a trigger, but I couldn't see a gun in his hands. I heard the gunshot and saw the lock get blown off, but no gun. So my question to those who have also seen this: Mind Bullets, or Invisible Gun?
