Rage Burst is a horizontal-scroll shooting game in ACG style. The story happens in year 2512. The human race was fighting desperately against the invasion of aliens from Bale, a planet of far more advanced civilization than the earth. Despite the struggle, the human race was routed by overwhelming alien technology, and the earth was turned into a colony of the Bale Empire. To regain independence, some human survivors established the Alliance of Watchers with the hope to defeat the Bale race one day and liberate the earth.
