Horizon Forbidden West, the biggest exclusive for PlayStation in 2022 yet, is now available to purchase and play on both PS4 and PS5. The highly anticipated open-world RPG continues the story of Horizon Zero Dawn regarding a post-apocalypse Earth and the survival of the human race. But humanity will have to wait to be saved again by just a little while longer, because while Horizon Forbidden West is now available it also has a day one patch that players will have to download before they play.
