The game uses a top-down, grid-based tactical view. Each scenario presents objectives such as defeating enemy forces, protecting an ally, reaching a location, or surviving for a set number of turns.

Players move allied units, choose weapons, manage energy or ammunition where applicable, and use spirit commands or other pilot abilities. Units gain experience during missions, while intermission screens support upgrades, equipment decisions, and roster management. The campaign proceeds through a branching sequence of battles and story scenes.

Check weapon range and terrain before committing a unit. Keep fragile support units behind tougher robots, and avoid ending a turn where several enemies can attack the same target.

Use experience and upgrades to maintain a balanced roster rather than concentrating every resource on one unit. Save powerful attacks for objectives or enemies that cannot be handled efficiently with standard weapons.
