A cooperative dungeon battler board game - not a dungeon crawler. Fight your way down, looting all the way.
Diablo: Unbound is an upcoming cooperative dungeon-battler board game from Glass Cannon Unplugged, published under licence from Blizzard Entertainment and crowdfunded on Gamefound in 2027. It is not a digital game - it is a tabletop miniatures game: hex-grid combat, deck-building skill cards, dice rolls, push-your-luck loot and a Torment mode endgame. This wiki covers the four classes, the three acts, the loot economy and what is confirmed about the boss roster.
The boss-battler showdowns and relentless hordes - but you do not crawl through dungeons. You battle your way down.
A boss at the end of every act, each with unique attacks, a lair and multiple combat stages.
Double-sided skill cards that upgrade from basic to advanced, combined with dice rolls on the hex grid.
Randomised drops from chests, Elites, side quests and kill streaks - with bosses holding the best gear.
Diablo: Unbound is a physical tabletop board game, developed by Glass Cannon Unplugged - the studio behind the Frostpunk, Apex Legends, Dying Light and Don't Starve board games, and the existing Diablo tabletop RPG - and published under licence from Blizzard Entertainment. It is not a video game and there is no digital edition. A playable prototype was shown at the Glass Cannon Unplugged booth at SPIEL Essen, October 22-25, 2026.
The project is currently on Gamefound with a pre-launch page live and the full crowdfunding campaign scheduled to launch in Q1 2027. Following the campaign claims a free, Gamefound-exclusive "Treasure Goblin" expansion. Stretch goals, exclusive rewards and additional content are promised but not yet itemised, and no MSRP or pledge tiers have been published.
The design is deliberately positioned against the dungeon crawler label. Glass Cannon Unplugged CEO Jakub Wiśniewski put it plainly: "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." It is set in Sanctuary, and it plays as a hack-and-slash inspired blend of deck-building and dice-rolling.
It supports 1-4 players, cooperatively, and is fully playable solo.
Fights use miniatures - heroes, monsters, Elites and bosses - on a hex grid, with dice determining the outcome of attacks and skill cards determining what you can do with them.
Each hero has a board with gear slots: chest, helm, ring, necklace, left hand and right hand - plus gem sockets, which are tracked separately from weapon and armour slots and are easy to forget entirely.
Skill cards have a basic side and an upgraded side, compared to the Slay the Spire board game. Upgrading happens in the Town Phase rather than mid-fight.
The campaign runs three acts of three dungeon levels each - nine dungeons - with a boss at the end of every act. Expect 60-90 minutes per dungeon and 3-4.5 hours per act.
Between dungeons you get a Town Phase to upgrade skills, manage and equip loot, and respec your build if you chose the wrong skills. It is the only window you get.
The endgame mode lets you fight any boss "regardless of their tier, in its ultimate form", scaled for endgame characters. It raises the difficulty and adds extra loot and event cards. It is an endgame unlock, not a starting option.
