Galaxy Ranger

Move your fighter craft around the screen to avoid enemy fire, colliding with the enemy fighters, mines, and other objects. Basically shoot anything that moves.
The game is divided into different waves. At the end of a wave there is a command ship which must be destroyed. Some waves required the player to maneuver their fighter through a trench while trying to destroy enemy fighters. With each successive wave the enemy fighters became more aggressive and accurate with their shots.
