Blizzard Entertainment and tabletop publisher Glass Cannon Unplugged announced Diablo: Unbound, a cooperative board game, on Wednesday during Spiel Essen, Polygon reported. Glass Cannon Unplugged calls the game a "dungeon battler" rather than a dungeon crawler.
You get the high-stakes showdowns of a boss battler—and hordes of monsters that never let up. But you don’t crawl through dungeons. You battle your way down. That’s why we call it a dungeon battler.
One to four players battle through dungeons, fight enemies and collect increasingly powerful gear in what the publisher describes as a "highly replayable cooperative action game" combining deck-building and dice-rolling. Four classes are playable: Barbarian, Rogue, Sorceress and Paladin, each with its own skill tree, abilities and progression. Glass Cannon Unplugged says additional classes will arrive through stretch goals and future expansions, and that the game pulls from the broader history of the franchise.
The game spans three acts of three dungeon levels each, with a powerful boss at the end of each one, and dispenses randomized loot, with greater risk tied to greater reward. Between dungeon runs, players enter a Town Phase to upgrade skills, manage loot and respec. Polygon reported that a single dungeon takes roughly 60 to 90 minutes and a full act three to four hours.
An endgame mode called Torment lets players face any of the game's bosses in its ultimate form regardless of tier, balanced to challenge a party of endgame characters.
Diablo: Unbound is in pre-launch on the crowdfunding platform Gamefound, and Glass Cannon Unplugged said it plans to reveal more over the next few months, with the full campaign launching in the first quarter of 2027.
Glass Cannon Unplugged has previously made tabletop adaptations of video games and other properties, among them Frostpunk: The Board Game, Apex Legends: The Board Game, Dying Light: The Board Game and Don't Starve: The Board Game. Polygon noted that the reveal came weeks after Diablo 5 was announced at BlizzCon 2026.
