Use the number buttons to switch between guns and press space to turn zombies on and off and you have to get the Rapid-Strike, Strife, Thunderblast and wizard staff from zombies. Post how many zombies you killed in the comments. If you get a new high score I will dab on you. Button maping, 1-Strong arm 2-Strife 3-Rapid Strike 4-Thunder Blast 5-Wizard Staff.
