Overview and Gameplay
Deep inside the orbiting station Cyberg, a malfunctioning planetary defense system threatens Earth, sending the M-308 Gunner on a high-risk infiltration mission. The station’s shifting architecture and hostile machines force constant adaptation as gravity itself becomes a tool for survival. The defining feature is the ability to invert gravity at will, letting the pilot walk on ceilings, bypass hazards, and attack enemies from unexpected angles while pushing through tightly designed action stages and boss encounters.
Progression moves through multiple mission zones filled with robotic defenses, environmental traps, and escalating encounter patterns that demand precise movement and timing. Each stage introduces new layouts that combine platforming and shooting challenges within the same space.
