We have to wait a bit, it's still work in progress. Just look at how the hud changed, as well as the hands and wristblades. I thought that energy emitting from the gauntlet was similar to Predator 1, when suddenly energy was building up, you saw everything get brighter, electricity in the background and then it blew up. It'll probably be the same in the finished game. At least I hope. The Mission could end with a giant explosion behind the Predator as he races to leave the area.
