Join Aloy on her perilous journey through the Forbidden West, a deadly frontier area where mysterious, new threats lurk. Explore distant lands, battle larger and more fearsome machines, and meet surprisingly new tribes as you return to Horizon's post-apocalyptic world of the distant future. The land is dying. Horrible storms and an unstoppable plague search for the scattered remains of humanity as fearsome new machines roam the borders. Life on Earth is heading towards a renewed extinction and no one knows why. It is up to Aloy to reveal the secrets lurking behind these dangers and restore order and balance in the world. Along her way, she must work with old friends, form alliances with new warlike factions, and decipher the legacy of the distant past - always one step ahead of a new and seemingly invincible enemy.
