Wizardry: Proving Grounds of the Mad Overlord is a classic role-playing game that immerses players in a richly detailed dungeon-crawling experience. The game sets the stage with a compelling narrative involving the power-mad Mad Overlord Trebor and his nemesis, the archmage Werdna, whose actions lead to the creation of a vast ten-level dungeon. Players must navigate this labyrinthine environment, battling monsters and seeking treasure, all while aiming to retrieve Trebor's stolen amulet and prove their worth for membership in his elite honor guard.

In Wizardry, players create a party of up to six adventurers, choosing from a variety of races and classes, including humans, elves, dwarves, and hobbits, as well as fighters, priests, mages, and thieves. As the party progresses, characters can evolve into more powerful elite classes, enhancing their abilities and combat effectiveness. The game features turn-based combat set in a 3D vector maze, providing a strategic challenge as players engage with various enemies and explore the depths of the dungeon.
