The Manhattan Project: Second Stage is an expansion for The Manhattan Project released in 2013 for 2–5 players, 120 minutes per game, and ages 13 and up. It was designed by Brandon Tibbetts and Eric Jome and its main mechanics are Variable Player Powers, Take That, and Open Drafting.
The Manhattan Project: Second Stage consists of four small expansions that can be added to the base game individually or together. Nations 2 works like the previous Nations expansion, with each player getting one card to represent a country and gain a special power. Seven new countries and powers are represented. Rocket Technology allows you to build a rocket factory when taking the "Design Bomb" action. Rockets work exactly like bombers - but fighters provide no defense against them. H-Bomb Technology upgrades the "Design Bomb" action, allowing a player to return an available bomb to the bottom of the deck in order to acquire an H-Bomb card. To build an H-Bomb, however, the player needs Lithium Deuteride, which comes from new cards that work similar to Mines. Personalities adds seven roles to the game based on real individuals who contributed to the Manhattan Project. Each time you retrieve your workers you will select a different role. Each role will grant you persistent benefits until the next time you retrieve.
The Manhattan Project: Second Stage supports 2–5 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 The Manhattan Project: Second Stage is 120 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 The Manhattan Project: Second Stage for ages 13 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.
The Manhattan Project: Second Stage has a complexity rating of 2.9 out of 5 from BoardGameGeek players, which makes it a medium-light 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.
