mARs Invader is an Augmented Reality (AR) game app that uses your device's camera and screen to display 'UFOs' invading your city on your device's screen. The goal of the game is to fire upon the UFOs to destroy it, this will earn one point and prompt another UFO. You may purchase extra UFOs with different designs by clicking the 'Extra UFOs' button and then pick UFOs to purchase. To restore all purchases, click 'Restore Purchases'. To add or remove purchased extra UFOs in each game, prior to starting the game press the 'Extra UFOs' button and make sure the switch is on (green) for each extra UFO you want in the game, firing upon one of these extra UFOs will earn ten points. Avoid enemy fire (red lasers) from the UFOs. You only have three lives and 100 ammo for each game then your score restarts to 0, unless you purchase more lives or ammo. Game score or points does not equate to any prize(s) or cash and there is no guarantee that your scores will be saved correctly in the app or Game Center. Please do not play this game or use your device while driving or operating a motor vehicle.
