Unknown is a board game released in 2016 for 1–6 players, 45 minutes per game, and ages 14 and up. It was designed by Robert Cutter and Dave Schroeder (II) and its main mechanics are Variable Player Powers, Tile Placement, and Modular Board.
"Unknown" is a cooperative tile based exploration and resource management game set in a post-apocalyptic world. Each turn players use their action points to move their meeples, explore new tiles, gather resources, interact with environmental hazards and battle enemies in order to complete objectives. Players must complete objectives while keeping the base supplied with food. If players fail to keep the base supplied with food before completing all objectives, the game is lost. "Unknown" features a vast array of characters, hazards, enemies and objectives that are mixed together each game, providing a unique experience every time.
Unknown supports 1–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Unknown is 45 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Unknown for ages 14 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Unknown has a complexity rating of 3.1 out of 5 from BoardGameGeek players, which makes it a medium-weight game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
