Surf the web guys! This is zombies gameplay with heaps of things in it, Dual Wield CZ75, Mystery Box, RPD, Juggernog, 2x points, max ammo, insta kill, new icons, Electric Brass Knuckles called Galvaknuckles, heaps of stuff. I saw on other leaks one of the leaked trophies from a while back, and double tap root beer. Check this video out.
