From the English rules:

Altamira - Hunters of the stone age

Altamira in the year 11,765 B.C. - You live together with other hunters in a cave. Sitting at the campfire, every evening you plan where you want to go stalking the next day to bring home food, furs, and material for new weapons. On the hunt you meet not only saber-toothed tigers, bison and cave bears, but mostly also hunters of neighboring tribes you have to stand up to. Whoever masters this best and captures the most prey will be honored as the most successful hunter.

You send your hunters to hunting grounds where they make weapons; with adequate weapons, they can kill animals on the hunt that follows. This gives you prey points. The player with the most prey points wins the game.
