Glass Cannon Unplugged announced Diablo: Unbound on October 21, 2026, the first officially licensed Diablo board game. Developed with Blizzard Entertainment, the project is a cooperative dungeon battler for 1 to 4 players with a dedicated solo mode, built around deck-building and dice-rolling mechanics. The game pulls classes, dungeons, monster families, and bosses from across the history of the franchise.
The four launch classes are Barbarian, Rogue, Sorceress, and Paladin, each with distinct playstyles, custom mechanics, dedicated components, skill trees, and progression systems. Deck-building gives each class deterministic build choices, while the dice add the same run-to-run variance that Diablo’s randomized loot has always traded on. More classes will arrive through stretch goals and future expansions, though Glass Cannon Unplugged has not said which ones or how many.
Dungeon battler is a design commitment
Glass Cannon Unplugged CEO Jakub Wisniewski described the game as a boss battler with hordes of monsters that never let up, where players battle their way down. Each of the three acts contains three dungeon levels that end in a unique boss, and each level takes approximately 60 to 90 minutes. A complete act runs about 3 to 4.5 hours, with a save system that splits the campaign into shorter chunks. Between encounters, a Town Phase lets players improve skills, manage loot, and respecialize builds before returning to the downward fight.
Pacing drives every session more than exploration does. There is no wandering search for hidden rooms. Players move through escalating combat, and the design pushes them forward through hordes of mobs, elite monsters, side quests, chests, and the occasional Treasure Goblin. Loot drops are randomized like the video game series, and the greater the danger, the greater the reward. Kill Streaks reward players for fighting successive hordes without slowing down.
The Town Phase mirrors the video game loop. In the ARPG, players return to town between runs to sell, craft, and retrain before the next descent. Here the same beat sits between encounters, so a session alternates between a tight dungeon sprint and a short planning window where the build changes. A solo player gets the same loop as a four-player group, and the dedicated solo mode plus a save system that preserves a partial act means the box works whether one person sits down for a short run or a full group plays a whole act.
Modularity replaces narrative
Diablo: Unbound has no single linear story. The game mixes classes, dungeons, monster families such as Khazra and Undead, and bosses from across the franchise, and after the three-act structure, Torment mode unlocks custom combinations of those pieces. Repeat play offers different class builds, monster family pairings, boss sequences, and randomized loot on every run. The risk-reward loop carries over from the video games, so hunting a Treasure Goblin or pushing a longer Kill Streak changes what drops and how dangerous the next fight becomes.
Glass Cannon Unplugged is working with Blizzard while the series keeps expanding, from the recently announced Diablo V, revealed at BlizzCon 2026 with a Spring 2029 release target, to Diablo IV, which keeps receiving seasonal patches including Patch 3.2.2 from September 30, 2026. The modular approach lets future expansions add new classes, dungeons, or monster families without breaking a fixed campaign. Glass Cannon Unplugged has not confirmed any post-launch content plan beyond stating that expansions will come.
The crowdfunding funnel is deliberately staged
The Treasure Goblin Expansion is a Gamefound Follower Gift. It requires two steps: follow the Diablo: Unbound prelaunch page now, and later back any physical pledge during the Q1 2027 campaign. The expansion keeps growing with new content throughout the prelaunch phase. Players who want the gift have to follow the page months before the campaign opens, and players who follow but never back a physical pledge get nothing. The stretch-goal classes remain unannounced, so the Treasure Goblin Expansion is the only named crowdfunding incentive right now.
No price, no pledge tiers, and no exact release date have been announced. The only confirmed timing is the Gamefound campaign launch in Q1 2027. That date marks the crowdfunding window, and Glass Cannon Unplugged has not stated a retail release date. The studio also has not said what the expansion will cost if sold separately or whether the Treasure Goblin Expansion will be available outside Gamefound. The studio’s board game portfolio includes Frostpunk: The Board Game, Apex Legends: The Board Game, Dying Light: The Board Game, and Don’t Starve: The Board Game.
The demo is playable at SPIEL Essen from October 22 to 25 at the Gates of Sanctuary booth in Hall 1, booth C611, with four tables running through the whole event. Glass Cannon Unplugged will keep revealing new details on the Gamefound prelaunch page over the coming months, and the Treasure Goblin Expansion grows with each update before the Q1 2027 campaign opens.
