Following the events of Star Fox Adventures, the Lylat System seems at peace. Dinosaur Planet (Sauria) is recovering, and the Star Fox team—Fox McCloud, Falco Lombardi, Slippy Toad, and Peppy Hare—are now galactic peacekeepers under the Cornerian Army. However, peace shatters with the rise of the Aparoids—a parasitic biomechanical race that threatens to assimilate all life into their hive mind.
Fox must face a new kind of war, one that doesn't just involve shooting enemies but fighting to save allies from being absorbed and corrupted. He reunites with old enemies and unexpected allies, including Krystal, now a full-fledged team member, and Wolf O'Donnell, whose rivalry may have to turn into reluctant alliance.
