Gloomhaven is a huge cooperative campaign in a box, designed by Isaac Childres and published by Cephalofair Games. You and up to three friends take on mercenaries in a grim fantasy world, clearing tactical dungeon scenarios that chain together into a branching story. Choices you make between missions unlock new locations, characters, and events, and permanent stickers and sealed boxes mean your copy of the game slowly becomes uniquely yours.
What sets Gloomhaven apart is that it has no dice for your own actions and no traditional hand of options refilled each turn. Instead, each class plays a small deck of ability cards, and every round you commit two of them face down before knowing exactly what the monsters will do. One card sets your initiative, and on your turn you use the top action of one card and the bottom action of the other. That simple structure hides enormous depth, because your hand is a finite resource that only shrinks over a scenario.
The tension comes from that shrinking hand. Cards go to your discard pile when used, and the only way to get them back is to rest, which permanently removes one card for the rest of the scenario. A short rest is fast but random, while a long rest lets you choose what to lose and heal up. Run out of cards to play and your character is exhausted and out of the fight, so the real clock is not your health bar but your dwindling deck.
Combat rewards planning over luck. Monsters follow predictable focus rules, targeting the nearest hero along the shortest path, while an attack modifier deck adds just enough swing to keep things sharp. Positioning, line of sight, the shared element board, and status conditions decide fights far more than a single big attack.
Win a scenario by completing its goal, usually clearing every enemy or reaching a target tile, before your whole party is exhausted. Between missions you level up, buy gear, retire characters who finish personal quests, and steer the campaign. Take it slow, learn your class, and let the story of Gloomhaven unfold one scenario at a time.
