Prehistoric Isle

Players maneuver their biplane across side-scrolling island environments using directional controls while firing primary weapons to destroy waves of airborne pterodactyls, marine reptiles, and massive dinosaurs. Collecting power-ups upgrades main firepower and attaches a rotatable option pod to the plane. The option pod can be positioned around the biplane to fire forward, downward, upward, or backward, providing crucial multi-directional coverage against surrounding threats.

During early stages, focus on securing weapon upgrades and positioning the option pod toward incoming hazard trajectories before facing screen-filling dinosaur bosses. As enemy density increases in later subterranean and oceanic levels, continuously adjust the pod's angle to block incoming hazards and attack boss weak points from safe angles. Staying mobile, anticipating monster movement patterns, and keeping defensive pod coverage active are essential for survival.
