Bringing additional depth to the Memoir '44 battlefield, the Breakthrough expansion features two super-sized, double-sided, hard-mounted Breakthrough board maps with Countryside, Beach, Winter, and Desert battlefields. Each board is comprised of nine folded panels stretching to an impressive 13 x 17 hexes deep. Also included are 15 Breakthrough scenarios featuring such classics as Operation Crusader, Operation Amherst, and two different renditions of the battle for Sword Beach. The Breakthrough expansion is not a standalone product and requires a complete copy of the Memoir '44 game to play.
