Feeling a bit like a Greenpeace revenge fantasy, Gemini Wing takes place in a far-flung future where the plants and insects of Earth have mutated into fearsome enemies threatening humanity's very existence, and the last two Gemini Wing fighters must push back against Mother Nature. Gemini Wing departs from standard shoot-em-up fare in numerous ways beyond its premise and visual style, most notably in its weapon systems — certain defeated enemies drop orbs known as Gunballs, which unleash a particular power on command, but not always in the way you expect. The Gunballs trail along beyond your ship and deploy in the order you grabbed them, which means you may or may not get the weapon you're looking for (but you can always pick up new ones). The game's fanciful style, lush natural environments and quirky enemies and bosses make it a pleasant departure from the usual shoot-em-up.
