Quartermaster General is a card-driven game that puts players in command of the major powers of the Second World War. In the game, supply is crucial to keep your armies and navies fighting; destroy your enemies' supply lines and their forces will surrender! You control one or more countries on either the Axis or Allied team and try to score as many victory points (VPs) for your team as you can through the use of cards or by occupying the starred supply spaces. Each major power has a unique set of cards with which to marshal its forces of army and navy pieces on a map. After twenty rounds the team with the most VPs wins.
