The Manhattan Project: Operation Crossroads

"The war may be over, but the threat isn’t gone. Although the bombs we’ve created thus far were successful, we must design, build, and test better bombs to ensure our safety. This defense contract will be given to the company who can successfully demonstrate that they are able to build the most powerful atomic bombs. Good luck."

In The Manhattan Project: Operation Crossroads, players take on the roles of several companies vying to win the defense contract for building an atomic bomb arsenal for the United States. To win, you must build and test bombs in order to prove that your company can produce the most powerful bombs. The player with the most points at the end of the game is the winner.
