The objective of the game is to survive each round of invading zombies after which a more 🌈 difficult round begins. The player begins the game with a Colt 1911 and has access to a melee attack via 🌈 a combat knife, as well as a maximum of 4 hand grenades.

Keep running around in circles as the zombies follow 🌈 you, turn around to get some kills, and keep running. Repeat this process to stay as safe as possible, while 🌈 being aware of your points (aka Essence). Ideally, you should open up the map as much as possible by opening 🌈 doors and unblocking pathways.
