The year is 2054, and Doctor Benomiya's escaped BEMs — Bug Eyed Monsters engineered in his fortress — are on track to end galactic civilization. The Super-Electric Research Center's answer is the ZanFighter, a compact but devastating space combat craft equipped with the Warp Slash, a superweapon capable of cutting through the traps and defenses inside Benomiya's fortress. The mission: reach Benomiya before the BEMs reach everyone else.
