When you open the app you will see the main menu and you will be able to select the character you would like to play with. After the selection the game will begin and your lonely ship will be cast into the alien abyss to fight for human survival. You will drag the ship across the screen with the tip of your finger and continually tap the screen to fire your guns. The more ships you destroy the more upgrades and health packs will become available to help you fight the alien invasion. See how long you can last and send those aliens back to their planet.
Overall, this is an excellent racing game for the Android platform. At the time of this review Alien Battle Android App is free. Thumbs Up.
