Hey dudes, I'm just going to share a little zombie technique which I use and has gotten me as far as level 41 On other threads I've posted what route to use 2 player and 4 player,(Kino der toten) but as for weapons, the weapons I used is, the ray gun, just b chance I got it lol ! but the main weapon I use is the upgraded ballistic knife and the bowie knife together. The knife is a fast melee and the bowie knife for power but after level 20 it gets useless, so just try this, use the raygun to make crawlers outta them and the ballistic knife/bowie knife kills in one go then! It's a great combination and you get way more points as a headshot with a gun is 100points and a knife kill is 130points. Plus the ungraded ballastic knife when you shoot it at a downed teamate you revive them instantly. It's the best method I've used for zombies and i play it everyday! Thanks for reading,
