In this video at 8.08 I get killed from spawn clearly the space in front of me where the shooting is coming from is empty, then the killcam shows "Die Boom" directly in front shooting me? but he was invisible to me?
Skip forward to 7.25 I get killed by "Die Boom" again, this time you can see his muzzle flashes on the right of the truck but he is invisible, watch the killcam again you can see him killing several people.
Skip forward again to 7.03 again I get shot by an invisible "Die Boom" and again you can see the muzzle flashes from his weapon just inside the door, but once more he's invisible, until you see his kill cam then you can see where he was.
