"This pack contains everything you need to upgrade your sci-fi gaming table with a prison cell block. The cell walls can also be used to block off areas of the board, and the lockers and bunks are perfect for a dormitory or barracks. The set is compatible with any of the Battle Systems Sci-fi Core Sets. The terrain is supplied flat-packed on high-quality, high-density card, printed in full colour on both sides, so no painting required! The terrain requires assembly, and some smaller parts will require glue.
