Take down enemy ships while avoiding their return fire. Survive long enough to advance in level and add another fighter to your fleet. Defeating particular ships creates opportunities for special attacks or for obtaining bonuses. For example, take out a specific type of enemy ship to create a black hole that transforms enemies into allies.Xbox.com: Galaga Legions Screenshots
