Sift Heads Assault is a side-scrolling shooter in which your goal is to survive for as long as possible. Shoot the stickmen and avoid their fire by taking cover behind vehicles, trees, and smaller objects that can be moved. When you die, you'll receive money based on how long you survived, how many enemies you killed, your precision, the number of items collected, and the number of explosions that you caused. Purchase guns and other equipment with this money.
