La Pucelle: Tactics (Playstation 2)

Set in an alternate medieval Europe, La Pucelle: Tactics tells a tale of betrayal, monsters in human form, and humans in monster form. You play an unlikely hero--a smart-mouthed 16-year-old girl who just passed her exorcism exams in La Pucelle, a demon-hunting squad. With your powers, you can purify defiled ground, damage multiple enemies at once, and carry special magic items. Turn your enemies into allies, organize your troops, and then either attack in waves or simultaneously to seize the high ground.
