"Deep Dungeon IV: Black Magician" is a first-person RPG in which a hero who seeks his father's keepsake sword forms a party with his friends and challenges the demon lord Saimaa. Accept requests in town, prepare equipment and magic, and explore the labyrinth using auto-mapping. While traveling, press B to open a camp, check status, and manage items and magic. Saving at the inn is important, and requests that don't appear to be the main purpose can lead to funds and important items.
