The player views each stage from above and explores a maze-like spacecraft. The main objective is to locate and rescue a required number of hostages before the countdown expires, then reach the exit and defeat the stage guardian when required.

Movement, shooting, and weapon selection are central actions. Enemies appear throughout the corridors, while power-ups improve the player’s firepower. Progression comes from clearing successive areas, learning routes, rescuing enough captives, and managing limited time rather than from experience levels or permanent character statistics.

Learn the layout of each area and prioritize hostages that are close to the route toward the exit. Avoid unnecessary detours, because the timer is often more dangerous than ordinary enemies.

Collect stronger weapons when they are safely available, but keep moving after securing the required hostages. Clear narrow corridors before entering them, and save room around the exit or boss area for evasive movement.
