The gameplay involves killing Zeds in a variety of forms and sizes, ranging from the spider-like Crawler to the hulking, smashing Fleshpound. Killing Zeds earns the player Dosh (in-game currency) that can be used to purchase armor, melee weapons, pistols, shotguns, automatic rifles, flame throwers, and other equipment to aid in survival. Completing kills also earns experience points toward different Perk skill trees, which grant players special abilities like buffs to damage, reload speed, and ammo capacity.
