Wizardry IV: The Return of Werdna (1987) is a challenging DOS role-playing game developed by Sir-Tech. Unlike its predecessors, players assume the role of the antagonist, Werdna, attempting to escape a multi-level dungeon filled with enemies and traps. Renowned for its brutal difficulty, the game requires strategic thinking, puzzle-solving, and summoning monsters to survive. Its dark atmosphere, intricate design, and reversal of the hero-villain dynamic make it a cult classic.
