Under Our Sun is a board game released in 2024 for 1–6 players, 60–180 minutes per game, and ages 14 and up. It was designed by Maximilian Lichtner and David Poluda and its main mechanics are Dice Rolling, Modular Board, and Cooperative Game.
Under Our Sun is a cooperative or semi-cooperative exploration board game set in a post-apocalyptic world where life is at the mercy of the sun. When a giant asteroid hits the sun, life on earth is suddenly at its mercy. Modern technology is no longer available, and the entirety of the northern hemisphere becomes a desolate hellscape as a result of the ensuing solar storms. Society’s rules and regulations are replaced by anarchy, and every day becomes a struggle for survival. Players embark on an adventure, assume the role of survivor, and join forces to reach a common goal. Players beware... everyone might not have the same goal in mind. As gameplay commences, you will become an integral member of one of the few remaining honorable and socially-minded communities. Players will choose between four unique characters (six with expansions), each with their own strengths and weaknesses, and will head into the wastelands to ensure the survival of the group and fulfill crucial tasks. The game can be played with a fully-cooperative approach, or to make things extra interesting, there could also be a traitor within the group. Choose one of the missions included in the core box, which are varied according to difficulty, play-time, and strategic approach. Under our Sun has a turn-based gameplay where each round represents a single day divided into different phases (morning, noon, evening, and night). Explore the area, tile by tile, to trigger events scattered throughout the map. Find precious loot and scavenge for resources to craft unique items in an effort to upgrade both your character and shelter. Engage in life or death fights against humans, animals, or something completely unknown. Adapt to ever changing weather conditions where even the most elementary of tasks results in a fight for survival. To succeed in this harsh land, players must manage resources, maintain their health, and ensure adequate water supply. Only through collaboration and the use of individual skills, will players be able to achieve survival and reach their ultimate goal (whatever that may be). —description from the designer
Under Our Sun 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 Under Our Sun is 60–180 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 Under Our Sun 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.
Under Our Sun has a complexity rating of 3.2 out of 5 from BoardGameGeek players, which makes it a medium-weight game.
