"Seicross" was released by Nichibutsu in 1986 for an 8-bit home console. In this shooting game, you pilot a hover bike to save the peaceful people of Petra, whose homeland has been invaded by a once-coexisting tribe that has turned to evil. As you rescue the captive people of Petra from enemy territory, your bike's weight increases, causing it to consume fuel energy much faster—but in return, you'll earn massive bonuses upon clearing the stage!
