Dungeon of Doom

Dungeon of Doom is a 3D dungeon crawler developed for the Apple II by Argon Games. It is one of the earliest CRPGs ever made and has both a 3D maze and grid-based battle system, perhaps the first grid-based battle system in any retail CRPG, far predating more popular games like Dragon & Princess and Ultima Exodus. It's a simple game and seems to have left no impact on the genre considering how absolutely obscure it is, but is of historical interest due to how few CRPGs exist in the pre-Ultima and Wizardry days.

The player creates their own party of 1–12 characters, who can be a fighter, magic user, or cleric. The player sets each character's strength, dexterity, intelligence, charisma, wisdom, and constitution, and can choose the character's equipment and enchantment level 1–5. Once the party is created, the player can start their adventure.

The player navigates a six-level dungeon from a first-person perspective. The player can access a map of the level, teleport, heal, or check their character and treasure status. The player can enter rooms for combat, or encounter random combats as they explore. Combat occurs on a separate screen, and characters and enemies take turns with movement. The player can cast magic or cleric spells with a force of 1–5, use ranged weapons, or engage in direct combat. The player gains gold and experience after victory, which can be used to purchase better equipment.
