This is a double-sided neoprene mat. The Homeland Expansion includes two new maps: The Gorge map has a wild geography, creating natural chokepoints and concentrating warfare in the central clearings, further emphasizing the importance of map position. The Marsh map can be changed in size during setup to suit your tastes. Play it with the standard 12 clearings, or make it larger to support games with 5+ players. This is an expansion. A copy of Root, the board game, is required to play.
