Astro Warrior — About this game
The Astro Raider flies through a vertically scrolling assault against the Devil Star Imperial Forces. Enemy formations and large installations fill the route through three defense zones. Supply ships improve your speed and firepower, giving you a reason to move beyond a safe firing lane. Surviving the approach matters as much as attacking the huge ships waiting ahead.
