In conjunction with the release of Alien Frontiers: Rocket Dice, Alien Frontiers' 4th Edition board is double sided. Side A has the standard docking ports for standard D6 dice. Side B has Rocket Dice docking ports that will comfortably fit Rocket Dice. The board is the same size as previous additions so you can retrofit your current copy of Alien Frontiers by adding a new board.
NOTE: The double sided board has a misprint on the standard D6 side, where the arrows showing which way the colonies are supposed to travel is missing.
