Players pilot a fighter through side-scrolling stages filled with enemy waves, terrain hazards, and boss battles. The game features a pre-stage weapon select system, allowing different loadouts for specific routes and threats. Standard weapons include a main shot, charged attack, and specialty options such as spread or homing fire. Some stages switch to top-down or multi-directional scrolling, demanding quick route reading and careful positioning. Progress is stage-based, with power lost on damage in many situations.

The player's fighter craft, equipped with interchangeable weapon loadouts.

Learn enemy spawn points and terrain changes so you can fire in advance and avoid getting cornered. Choose homing-style weapons for unfamiliar stages and spread-style weapons for clearing crowds or close-range boss damage. Against bosses, stay at a safe mid-range and focus on removing the most dangerous attack patterns first. In scrolling-heavy stages, memorize safe lanes and do not chase every pickup if it puts you into danger.
