Horizon Zero Dawn: The Frozen Wilds is the sole Horizon Zero Dawn DLC expansion.

This expansion brings Aloy to the Cut, a region on the border of Banuk territory accessible via a mountain pass just north of the Grave-Hoard. While the gameplay is accessible any time after leaving the Embrace during the main quest A Seeker at the Gates, the add-on's content is balanced around a player that is level 30 or higher and is best played after completing The Mountain that Fell from a storyline perspective.
