The Operation Overlord expansion was specifically created to aid setup and enhance the play of multi-player Overlord scenarios.

Included are: 2 special decks of updated Command cards that provide players with the correct card makeup for Overlord games, 2 punchboards of Army figure tokens that are used to represent figures from different nations and make it possible to play Overlord with only a single copy of the base game. Also included are 8 Memoir '44 dice for the additional players and an updated version of the Overlord Rules.
