How long does a Diablo: Unbound campaign take?

Diablo is getting a board game, and it is not a tie-in coaster with a dice tower. Glass Cannon Unplugged, working with Blizzard, announced Diablo: Unbound on Wednesday, which the publisher's announcement calls "the first-ever officially licensed Diablo board game." It is a co-op game for one to four players, solo mode included, and the Gamefound campaign is scheduled for Q1 2027. A prelaunch page is up now.

Glass Cannon has done this before. Polygon's writeup lists Frostpunk, Apex Legends, Dying Light and Don't Starve among the studio's video game adaptations. So the question is not whether they can make a big box. It is whether a Diablo night fits on a table.

How it plays

The pitch is what Glass Cannon CEO Jakub Wiśniewski calls a "dungeon battler." In the release he puts it this way: "But you don't crawl through dungeons. You battle your way down." Translation: less exploring corridors tile by tile, more fighting waves.

From the announcement and Glass Cannon's game page:

• Four starting classes: Barbarian, Rogue, Sorceress and Paladin. Each has its own skill tree, components and progression. More classes come through stretch goals and later expansions.
• Mechanics: deck building and dice rolling together. Loot comes from your class's own equipment deck.
• Structure: three acts, three dungeon levels each, with a unique boss at the end of every act.
• Loot sources: chests, side quests, Treasure Goblins, Elite monsters, and Kill Streaks built by chaining through hordes. More danger, better drops.
• Town phase: between fights you portal back to town to upgrade skills, sort loot and respec your build.
• Torment mode: unlocked after the three acts. You mix dungeons, monster families such as the Khazra and Undead, and bosses into your own runs.
• Story: no single plot. It pulls from across the whole series.

The respec detail is the one that tells me the designers actually play Diablo. Being able to tear your build down between dungeons is half the fun of the video games. Board game campaigns usually punish that, because rebuilding a character means re-sorting a pile of cards. Building it into the town phase is a good sign.

A full three-act run is nine dungeon levels. At Glass Cannon's own times, that is at least nine hours of table.

The question nobody has asked yet: how many nights?

Glass Cannon gives two numbers. A dungeon level runs about 60 to 90 minutes. A full act runs about 3 to 4.5 hours, and there is a save system so you can stop between sessions. Polygon has the act at "three to four-ish hours," which lines up. From there it is arithmetic, and the totals below are my math, not the publisher's.

Two caveats. Those times are the publisher's, and publisher times tend to be optimistic at first. Also, nobody has said whether the numbers assume a full table or a solo player. With four players taking turns I would budget toward the top of each range.

That is a reasonable size for a co-op campaign. It is a lot shorter than the big legacy boxes and a fair bit longer than a one-shot. For a solo player, a dungeon level a night sounds like exactly how I play the video games anyway: one more run, then bed. Then one more.

Follower gift and how to try it

Glass Cannon is using the usual Gamefound carrot. Follow the prelaunch page now, then back any physical pledge later, and you get the Treasure Goblin Expansion as a free Gamefound-exclusive gift. The studio says it will grow during the prelaunch period. You can try the game before the campaign, too: Glass Cannon is running demos at SPIEL Essen from October 22 to 25 at a Gates of Sanctuary booth in Hall 1, booth C611, with four tables. For everyone else there is a Tabletop Simulator playtest through the studio's Discord.

Video games keep turning into crowdfunded board games this month. Last week it was the Satisfactory board game on Gamefound, and yesterday I broke down which Final Fantasy to play first in Origins of Light, which has the same issue of session length hiding inside a friendly box. Diablo: Unbound at least tells you its numbers up front. I will take that.
