Shoot the aliens before they throw rocks at you.
Shoot the aliens with your laser before they get the chance to throw rocks at you. The aliens will make a noise before they appear out of their holes and the faster you get them the more points you will get. If you are hit with a rock you will lose one of your 5 lives and with each alien you hit the faster they will start to appear. If a rock has been thrown at you then don't worry you can hit it before it gets to you. You can also get extra points by hitting the ufo.
The default controls for the game use your device's gyroscope. So to play the game you can either stand or sit on a swivel chair with the device held in front of you. You can then turn 360 degrees to see all of the alien's holes surrounding you and when one pops up, aim using the red circle in the center and tap anywhere on the screen to fire.
Alternatively you can change the controls to use a joystick instead so you don't have to move around. With this control option you can use the joystick on the left to look around and the red button on the right to fire the slingshot.
Your highest score will appear on the menu page. How many points can you get?
