Oathsworn is a cooperative fantasy board game for 1–4 players that combines narrative decision-making with rich miniature combat encounters. Set in Deepwood, players take the role of the Oathsworn, a Free Company fighting to ensure humanity's survival against unnatural horrors and the forest itself.

Each game session unfolds through a branching storybook, where player choices shape the narrative before leading to an inevitable climactic encounter.

Combat takes place in multi-phase boss battles against AI-driven enemies. Success depends on teamwork, careful planning, and adapting to each encounter's unique challenges.

As the legacy campaign progresses, characters gain levels, collect loot, and recruit new allies to strengthen their company. The game features a distinctive push your luck combat system using exploding dice, forcing players to balance stronger attacks against the risk of missing. This is combined with the Battleflow cooldown system, adding another layer of tactical decision-making to every battle.
