The Motherload is a Traveller one-shot scenario for 1-5 players. Designed to be played in a single session, the PCs find themselves working beneath the surface of a far flung asteroid.
Cold-Rock is god forsaken place, but beneath the surface are riches to be mined. When the crew strike the motherload they encounter more than just minerals. Instead they discover an alien horror that spreads like a disease, and are left fighting for their lives against raging beasts and the cold hard vacuum.
