Each stage presents a tactical objective on a grid map. The player moves allied units, selects attacks, manages weapon ranges and ammunition, and tries to defeat enemy forces while protecting required units or meeting scenario conditions.

Story intermissions provide dialogue and access to upgrades, pilot development, equipment allocation, and unit deployment. Progression comes from earning funds and experience during missions, then improving robots and pilots before the next battle. The campaign follows a sequence of scenario maps with route and story developments.

Use terrain, weapon range, and movement order to keep fragile units away from concentrated enemy attacks. Check enemy weapons before ending a turn, and avoid spending limited ammunition or energy on low-value targets.

Prioritize upgrades for units that will remain in the active roster. Gain experience safely when possible, but keep enough resources for difficult objectives and bosses. Save before major route decisions or challenging maps.
