The protagonist often enters and explores first-person 3D dungeon-like areas, where he can physically move around and also encounter enemies. Battles take place on a separate screen; the hero fights by aiming at enemies and shooting at them in real time. Each action in combat costs action points (AP); once the main character's AP bar is depleted, he cannot perform actions until it refills gradually or until the player uses an AP-restoring item. It is also possible to use shields and various offensive items during combat. Weapons and items can be bought in stores. Many boss battles require the player to locate the enemy's weakpoint and attack it.
