A pilot navigates a spacecraft through hostile planetary systems, where each world is defended by gun emplacements and a central power reactor. Destroying the individual turrets is straightforward, but the real objective requires targeting the reactor itself—bombarding it until its systems overload and trigger a catastrophic chain reaction that will obliterate the entire planet within seconds. The player must then race against the countdown to reach open space and survive, optionally recovering a valuable pod for bonus points before the explosion consumes everything. Managing limited fuel becomes crucial to success, as the ship's maneuvering capabilities depend entirely on fuel reserves, which can be replenished by using a tractor beam to collect resources. Strategic choices emerge between offensive firepower, defensive shielding, and fuel conservation, since activating the shield drains the very resource needed to escape.
