Deep in space, the V-class planet Trisula Ultra is home to a thriving, industrious civilization living in comfort and freedom — until a breakaway faction emerges with ambitions to change everything. Having developed a new branch of science that could make them invincible, the faction needs to locate a peculiar collection of objects scattered across the planet to complete their super defence shield. Jellyhead, a volunteer from the group, is sent to retrieve them. But the established powers have dispatched their own agent to intervene: the relentlessly positive Dr. Subtech Plus, whose mission is to reach those same objects first and shut the plan down. The two sides perceive the world as mirror images of each other — everything appears back-to-front to the opposition — and the player chooses which of them to champion.
