OBJECTIVES
The zombies are rebelling! They've had enough of their captivity at the bottom of a desert canyon and are on a mission to eat human brains.
A bounty has been placed on all escaping zombies. Your objective is to kill them before they reach to top of the canyon and wreak havoc on the citizens of Zombville.
Kill them well, make money, upgrade your weapon and buy other power-ups. Good luck!
