Very good

Just got to round 44 with 1029 kills. Kind of repetitive but still entertaining. Best strategy for me is run around get all the zombies then shoot. If its lagging for you just turn off blood and ragdolls and it wont lag till about 35 to 40. CHEATS: Electric gun: sparky, Minigun: minifun, Black hole gun: vortex. I strongly suggest this game for zombie lovers hope the codes help and have a good time with this game if you choose to buy it.
