Players: 2

War Plan Crimson is a simulation game of a hypothetical invasion of Canada by the United States some time between 1935 and 1939. The game is for two players, one representing the leader of the armed forces of the United States that could be deployed against Canada (the US player) and the other representing the commander of the Canadian and British forces that would defend against a foreign invasion (the Commonwealth or CW player).

The 11 x 17″ map depicts the areas around the city of Halifax in Nova Scotia (the East Map) and the approaches to Montreal from the American border (the West Map). The 280 counters show cadres, battalions and brigade sized forces from Canada, the US and Britain.
