Manhattan Project: War Machine calls upon players to set into motion the wheels of war production. You and your fellow players are working to create the perfect machine that creates as many resources for the war effort as possible. Will your machine be lean, mean, and efficient, or hungry and wasteful but powerful? On their turn players will roll die and assign the results to a shared board. Be careful what you select as some actions will allow other players to act as well. These actions allow players to gather resources, gain energy, and build their engines.
