You are the last defender on the surface against the attack of the aliens! Use the turrets to fire missiles to their battle ships, which are trying to fall into the entrance to the subterranean base. If too many alien ships enter behind the surface, you will have to go down to track them down in the maze-base.

Use the mouse to target the ships and fire the missiles. Use the mouse or the arrow keys to find and engage the aliens in the maze.

This old-style game has been made uding the LibGDX framework and Gimp for the graphics. Please, try to imagine a 8 bit music and efects while you are playing (I had no enough time to make the music ;).
