What is Build a Dungeon?

Build a Dungeon Wiki

Build a Dungeon is a free-to-play Roblox simulation and tycoon game created by Exploration Guild. Rather than raiding a dungeon as a hero, you build one, station monsters inside, and earn resources as your defenses defeat invading heroes.

Collect stronger monster units and buildings, improve your dungeon layout, and spend Coins and Dark Souls on further progression. The beta also features a randomized three-floor Labyrinth with solo or group exploration, shared rewards, and shrine tiles.
