The best map so far is moon
earth gets over run by zombies
only place left to go is moon
zombies follow humans to the moon
fight them in 0 gravity..use hacking device to go far in game
biodome great hangout and hacking the ak74u for unlimited ammo..
easter egg 8 perks eve keep them if you fall down ..
the moon map pack also brought the old school waw zombie maps
verukt, shi no numa, der riese, nacht der totten
they added mule kick perk to the old school maps so you can have extra weapon
so far i made it to round 41 on moon 33 shi no numa 25 verukt, 37 der riese
