Return of Invaders

In Return of Invaders, you are a planet-bound gunship protecting your planet from airborne alien ships. Fire at the invading ships to destroy them, hiding behind barriers to avoid getting hit by their unfriendly fire.
Best played as a two-handed game- hold a finger on the left controller and slide slightly right or left to move your gunship across the bottom surface of the screen. Press or tap the right button to fire.
