So if you send a worker to the forest to collect wood and berries, they might end up in the mountains collecting herbs, on the plains hunting for fur, or in the "Love Tent" making...your population larger. They might also bring some predators out of The Passage with them ? or not come back at all.
Players use the resources their workers end up with to arm their workers with spears and drums, to build a larger cave, or to create an invention, which earns victory points for their tribe. The first player to have 10 victory points wins!
