Ok guys me and my friends used to be epic at this game heres mine
Solo Naucht- Lvl 24 (it gets WAY too hard near then) 4 People- Lvl 54 For a while we had the number 1 score but some people glitched and got to like lvl 200.... Verreduct Solo-around 20 4 People- lvl 56... We played Nazi Zombies for 24 hr strait. the only reason be passed Naucht was BOuncing betties and soda
TIPS: When you get to the electricity room, DO NOT OPEN THE OTHER DOOR. If you NEED to get to the other side kill all the zombies but 1 and walk all the way around. The only way the flamethrower is of use is infinite ammo of course, and when a mass of zombies is approaching you, burn them then have a machine gunner fire into the burning mass, that will utterly annihilate their ranks. Double Tap Root Bear, and Speed Cola lead to a SWEET combination for the first 30 lvls Once you get above lvl 30 EVERYONE needs juggernog
Hope they help ~NinjaStoner~ P.S. If you think I'm lying get 3 people together and invite me to a game. My gamertag is RedDyeC8
