Horizon Zero Dawn The Frozen Wilds extends the Horizon Zero Dawn post-apocalyptic action adventure where you explore an overgrown landscape with now-crumbling remnants of modern life. The story of Aloy continues as she sets out to investigate a plague terminating from an arcane frontier known as the Forbidden West.

As Aloy, you venture north into The Cut. This leaves the warm lush valleys behind. Instead, the north is harsh, frozen and occupied by the stronger Banuk Tribe. They believe the machines are possessed by demons, something you agree to help them with.

The story runs alongside events of the main game which means you need to have completed some of the main game to access it (from the Enemy at the Gates quest line). As well as the new regions, there are five new machines, additional weapons and a new Traveller skill tree.

But this is more than an expansion of the original. The game has been upgraded visually as well. Motion capture and facial animations have been improved as well as more dynamic camera work and snow effects. It's clearly a stepping stone for the developer on the way to making Horizon Forbidden West.
