Under Game Awards afslørede Guerrilla Games den første, og måske eneste, store udvidelse til Horizon Forbidden West, Burning Shores. Den udkommer i løbet af foråret, men selvom at hovedspillet er tilgængeligt på PS4, så vil udvidelsen ikke kommer til Sonys gamle konsol.
I en udtalelse til PlayStation Blog siger instruktør Mathijs de Jonge følgende:
"Our creative vision for the Burning Shores is an ambitious expansion which will take Aloy to the ruins of Los Angeles. It's an overgrown and fractured city that can be fully explored via the water and flying on the back of a Sunwing. A massive machine threat lurks in its shadows - a huge challenge that Aloy must overcome by using all of her skills and abilities. To achieve this grand vision technically and creatively, we've made the difficult decision to focus all our efforts on making an incredible experience exclusively for the PlayStation 5 console."
