Galaxy Force II is an expanded version of Galaxy Force . It adds two additional levels, the old levels are revised (expanded and re-balanced) and the four missiles can be fired with a single button press.
You are strapped into a spaceship to take on six dangerous settings. The journey will take you through pleasant gardens, hostile fire, and tough ice. You will have to fly freely before cutting through tunnels and canyons, and finally destroy an alien base. Your energy readout starts at 1200 and decreases as shots hit you, or you make contact with a wall or blockage. You have infinite cannons and guided missiles to help you along. You can get regular energy recharges and power upgrades by shooting and then collecting their carrier pods.
