Unlimited money, all weapons unlocked. No other hacks as they are premium content. Scoreboards disabled.
After successfully completing the first mission in USA, our hero is now sent to an abandoned military camp, again overrun with Zombies. With more firepower, ranks and skills to unlock this time you should have no problems.
Use WASD KEYS to move around. Use YOUR MOUE to aim and click to fire. Press "R" KEY to reload your weapon. Use "Q" and "E" KEYS to change weapons. Press "F" KEY to barricade windows / unlock rooms. Press "G" KEY to throw a grenade. Use SPACEBAR to pause/shop/choose weapon. Good luck!
