One hundred years have past [sic] since the Alien Invasion of Corridor 7. An evil intelligence has once again assembled a deadly army of warriors, bent on conquering the universe. Total destruction of the planets Ailoprobe and Semaj by the evil force has convinced other alien races to fight against them. This has created a chain reaction of events, resulting in the unification of the Rodex, Mechanoid and Human race in an attempt to fight the evil force. Corridor 8: Galactic Wars takes you there! Which side will you choose?
