Crysis is a first-person series. There is no third-person perspective. And we should be forever grateful for that.
Why? Because this. This is what happens when you tinker with the game and see things from outside the player’s body. Because it’s an FPS, there is no head. There is also no concern given to things like animation, because why would they? You’re never supposed to see any of this.
Not that any of that will make this any less hilarious/terrifying.
