Zombies ate my Phone

The zombie apocalypse has started, and you need to save your friends from the zombies! As each level starts, you have to answer or reject your friends' calls to decide who you are going to save. Then you hit the streets with a fire extinguisher as your starting weapon. Use W, A, S, and D keys to move your character around. Use the direction keys on your keyboard to aim and shoot your weapon at zombies. After you clear each wave of zombies, visit the store. This allows you to upgrade your weapons. Clear the levels to save your friends and end the zombie problem.
