In Zombie Killing Spree, you are exploring the park in the middle of the dark night. The zombies are out, and as soon as they are caught in the light of your lantern they will become visible and charge at you. Make sure to dash out of the way and shoot them. Be especially careful of the bloated green zombies. They will explode when they die, and toxic goo will splatter and splash around them. If you get hit by the goo, you'll get infected and die almost instantly! Buy upgrades between levels to make your character faster and more deadly.
