addedThe Prehistoric Planet Pack travels deep into the past, to a forgotten world ruled by ancient dino-like critters—some so big that their stomping will auto-harvest crops, others so prey-driven that they can't be trusted in a ranch. (Do they also have a taste for Duplicants? Only one way to find out.)
