Welcome to Earth Defender, where you are the sole defender of an alien invasion.
Earth Defender supports both touch screen and keyboard controls. Touch screen controls (on-screen buttons) are shown by default, and can be turned off via the settings menu.
The goal of the game is to repel the alien invasion before they reach your ship. This is done by rotating your ship while in orbit and shooting the aliens. The game is over when an alien collides with your ship. The further you progress in the game, the faster the alien waves come.
