Betrayal at Baldur's Gate – D&D Meets Hidden Traitor
Explore the dark alleys and catacombs of Baldur's Gate — until one hero betrays the rest. 50 unique haunts, 12 adventurers, and no two games alike.
Betrayal at Baldur's Gate is one of the most original D&D board games ever created. Published by Avalon Hill, it takes the beloved hidden traitor mechanics of Betrayal at House on the Hill and transplants them into the dark, dangerous city of Baldur's Gate — delivering a game where every session tells a completely different story.
Explore the city together. Discover omens. And then — when the haunt triggers — one hero becomes a traitor with their own secret agenda, and the rest must figure out how to survive. With 50 different haunts, no two games ever play out the same way.
Players who discover Betrayal at Baldur's Gate consistently describe the moment the haunt triggers as one of the most memorable in all of board gaming — the shift from cooperative exploration to sudden betrayal creates a tension nothing else quite replicates.
What Is Betrayal at Baldur's Gate?
Betrayal at Baldur's Gate is a semi-cooperative exploration and hidden traitor game for 3 to 6 players. Players choose from 12 pre-generated adventurers — each with unique D&D abilities — and explore Baldur's Gate by drawing tiles, revealing new city streets and underground catacombs.
As they explore, heroes collect items, trigger events, and discover omens. Each omen triggers a haunt roll — and when the haunt finally triggers, the Betrayal Book reveals which player becomes the traitor and what terrifying scenario unfolds. The remaining heroes must work together to stop the traitor's plan before it succeeds.
The Two Phases
Exploration Phase
Heroes explore Baldur's Gate together — drawing tiles, collecting items, and discovering omens. Cooperative and tense.
The Haunt
One hero becomes a traitor. The Traitor's Tome reveals their secret goal. Heroes must stop them before it's too late.
50 Scenarios
50 unique haunts drawn from D&D lore — each one creates a completely different endgame scenario.
12 Adventurers
Unique D&D characters with special abilities — Eldritch Blast, Flurry of Blows, and more.
How Does the D&D Setting Change Things?
The original Betrayal at House on the Hill uses a haunted mansion setting with gothic horror. Baldur's Gate replaces that with the dark fantasy of D&D — city streets, catacombs, taverns, and temples replace the mansion's rooms. The omens and events draw from classic D&D lore rather than horror tropes.
The character abilities feel authentically D&D. The Wizard's Eldritch Blast, the Monk's Flurry of Blows, the Rogue's cunning — each adventurer plays differently and rewards players who understand their character's strengths. For D&D fans, the familiarity of the setting and characters adds a layer of immersion the original Betrayal can't match.
The two-level map — city streets above and catacombs below — creates more spatial complexity than the original game, with different tile types and encounters in each zone.
