Galaga '91 — About this game
Galaga ’91 for Game Gear mixes classic formation shooting with ideas from Galaga ’88. Your fighter moves horizontally while enemies arrive in patterns, settle into formations and dive toward you. Watch the gaps between shots instead of following a single target across the screen. A captured friendly craft can be recovered to form a Dual Fighter, expanding your firepower. This version stops short of the further ship combination from Galaga ’88 and instead provides a special cannon. Static screens, scrolling passages, bosses and dancing challenge stages change the rhythm of play. Extra fighters come from preset score thresholds, so collecting points also helps survival. Protect the wider combined craft carefully rather than treating extra firepower as protection from every attack.
