The HOME Empire has attacked the central planet of the Stonham Empire using its powerful new P45 Ray weapon, destroying the planet and leaving only a few survivors. The HOME Empire now controls most of the former Stonham Empire. The last remaining hope rests with rebel warriors from the destroyed planet who have fled to Planet Malt. Outnumbered and outgunned, the rebels must stay hidden from the powerful Death Stott spacecraft carrying the P45 Ray, which can traverse the universe in a single day. However, the first ship carrying the P45 Ray, the Houlligun, mysteriously disappeared after its first flight, potentially providing the rebels with hope.
