(adsbygoogle = window.adsbygoogle || []).push({}); OKay guys i just did this today and this strategy works and is fool proof all u need is 2 people, one with ray gun and another with ray gun and thunder gun... Go to the stage and run around in circles, the people with ray gun shoot at zombie legs only one time! and then when u get a whole lot of crawlers get the guy with thunder gun and make him kill all the crawlers with 1 boom.... anyways have fun i went to lvl 36 but then was bored and killed myself... I did this with 2 people, but u can try with more but make sure you all are together while running in circles!
Any questions? feel free to ask.
This saves a lot of bullets and crawlers are easy to doge so its easy with easy!
If u seem to run out of ammo then turn on the turret to fire bullets at zombies .

Why make them crawlers first? They die through the blast of the thundergun anyway

easy to maneuver around crawlers, u can jump over them

Do laps, that's an easy way to get high rounds.

Gameshare. I need the Classic W@W maps on Blackops. I have mic. I've gotten to 31 on kino. Messeage me bearable

Just trying to help some people....
and when you are doing laps, the stair cases are a problem and especially that room that is connecting lobby to alley

simple just get 2 ray guns and a thundergun. i can use the mystery box 12 times in a row and not get the ray gun

idk i get a ray gun usually in early rounds really easily.... But it is your choice if you want to follow this or not....
