The Galuga Archipelago (ガルーガ諸島 Garūga Shotō?, Lit. "Garooga Islands") is a fictional chain of small islands off the coast of New Zealand. It is in this place where the alien army known as Red Falcon first made contact on Earth and began their first invasion.
The archipelago is a small chain of islands off the coast of New Zealand, sitting in the southwestern Pacific Ocean. As expected, it has tropical weather and beaches surrounding it, with the usual vegetation and fauna proper of these regions, mainly composed of dense jungles, rivers and cascades, although inner lands have developed big mountains with icy landscapes and constant snowstorms.
It is in these latter areas where the local government has constructed industrial zones, which ended up being taken over by the alien forces during their invasions and adapted to the bio-organic environments they use to survive.
In 2633, the evil Red Falcon army set a base on the archipelago in a plot to conquer the world (or so it was initially thought). Two commandos, Pfc. Bill Rizer and Pfc. Lance Bean of the Contra unit (an elite group of soldiers specializing in guerrilla warfare), were sent to the island in order to destroy the enemy forces and uncover the true nature of the alien entity controlling them.
In 2638, two years after the Alien Wars, a similar alien entity calling itself Black Viper began launching attacks against the human race, causing mass destruction over the planet. After strange readings were detected at the Galuga archipelago, the Earth Federation sent their four strongest Contra Force commandos: Bill, Lance, Mad Dog and Scorpion, on a final strike mission to destroy Black Viper and its army of aliens, robots and mutants.
