Doodle Zombies is a simple nice looking scrolling game. Use your left thumb to move the character and your right thumb to shoot. Killing the zombies is the only mission that you have to do. Kill them before they kill you. By the way, these zombies have guns! They don’t bite, they shoot. Everytime you level up, it will become harder too. There will be more zombie hordes to exterminate. To help you with the horde, you have two options: a bomb and a bubble. You will be protected by the bubble while killing them or you can use the bomb and kill all the zombies around you.
