~Hints~

I Hear For the Zombie Map Kino Der Toten When you have the power on and enough points, You should buy Jugger-Nog.Be sure to leave 1 zombie alive one whos had his lower limbs blown, so he crawls. Position yourself between the Turret next to the Teleporter and the zombie and when the zombies attacks jump and you will be nocked on top of the turret makeing it almost impossible to be touched buy and zombies. So pretty much invincibility. It will take some practice and good timing to achieve that so Have fun More to be added soon...
