The Manhattan Project: Nations Expansion

The Nations expansion introduces 7 cards that turn each player into a global power—Britain, China, France, Germany, Japan, the Soviet Union, or the USA—in the frantic race to build the atomic bomb. Each card acts as a “building” that is immune to air strikes and espionage, ensuring each nation’s unique identity and strategy throughout the game. The Open Drafting mechanic lets players choose their cards from an open pool, while Take That creates direct tension, allowing each choice to involve resource swaps. Combined with Worker Placement and Variable Player Powers, each nation has a distinct playstyle, placing workers in strategic spots to gain bonuses reflecting their history and technology. The result is a 2‑to‑5 player, 120‑minute game of diplomatic and industrial competition set in World War II. If you love deep strategy games with historical themes and want to try different approaches for each country, this expansion will surprise you.

The design keeps the simplicity of the base game while adding layers of decision-making that require attention to timing and worker allocation. Each nation’s “power” can change the dynamics each round, and the construction cards are essential for protecting operations. The expansion works well for both beginners and veterans, as it keeps the learning curve approachable but offers enough strategic depth to keep the game interesting. The only caveat is that the playtime can be a bit long for those who prefer quicker games.

In short, Nations is a solid add‑on that expands The Manhattan Project universe, bringing more variety and new strategies for those who already know the base game and want to deepen the historical and competitive experience.
