Publisher's blurb: Build the ship you need for the mission at hand... This set of 12 double-sided terrain cards (plus two extras on the back of the covers) provides everything you need to build your own scientific research vessel, survey scout, or starfighter carrier gunship! Mix and match the tiles to create countless variations, and rearrange them as needed to change the configuration of your own specialized spacefaring vehicle! With two sets you can double the size of your deck plan, or display two completely different vehicles at the same time... Each card measures 5 by 8 inches, and is printed on thick glossy cover stock. The complete printed set is gathered in a clear resealable envelope for safe and easy transportation.
