The Frozen Wilds might be a familiar region.
GamesRadar has analyzed the E3 reveal trailer, and they got to two conclusions after their in-depth look. First, the site believes based on the artwork and the trailer, which both feature the wildlife and the hot spring, that The Frozen Wilds’ Ban-Ur could be based on the Yellowstone Park. That sounds reasonable. They also think that a new enemy could be a robot bear/gorilla hybrid. We’d rather not quote their two (!) paragraphs of description.
Horizon Zero Dawn: The Frozen Wilds will launch later this year on PlayStation 4.
