Small World: The Lost Tribes' Crusade

As the sun touches the mountain tops with predawn light, the Lost Tribes of Small World creep out of the shadows. After centuries of humiliation, they've emerged for revenge. Can you survive their retaliation? With this mini expansion for solo play and 2-player games, you will play against a non-human opponent (the Lost Tribes) controlled by elegant rules and moved by you. This expansion can be played using Small World, Small World Underground and any of their expansions. —description from the publisher
