"This pack upgrades your sci-fi gaming table with a particle transmitter or teleporter. It is perfect for beaming characters off-planet for a quick escape, and the base is reversible with two colour options. 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.
