Urinating Brute

On the level "The Ark", when you reach the room with sleeping Grunts after destroying the Scarab, by the door you go to through to continue farther in the level there is a Brute taking a "break" in the corner. He originally has his hands in front of him, but after a short time he will move his hands behind his head and then shake the excess urine off.

It is also argued that the brute is masturbating. OwWoYvO4Efo
