The campaign is presented from a top-down perspective across a sequence of tactical maps. Players move army units, capture objectives, defeat enemy formations, and manage terrain, equipment, morale, and character compatibility.

Each turn uses a limited movement allowance. A selected leader can form a Union with nearby allies, creating larger engagements than a unit's position alone would suggest. Victory depends on choosing the right leader, arranging the formation, and exploiting weapon and terrain advantages.

Cards provide special skills with effects such as attacks, healing, movement, or status changes. Battles and story events gradually expand the roster and equipment options, but defeated units and spent resources can make later maps considerably harder.

Plan each map before moving. Check weapon matchups, terrain effects, and the order in which leaders will enter combat. Keep fragile characters out of unfavorable engagements and use a strong leader to anchor a Union.

Preserve useful cards and morale whenever possible. Capture objectives early when the map allows it, but do not split the army so far that isolated units can be surrounded. Review equipment and unit statistics between battles, especially before boss encounters.
