Set in the 31st century, ABYSSAL takes place in a post-apocalyptic United States where nature has reclaimed the ruins of a forgotten civilisation. The world is overrun by zoomorphic machines that function as the dominant ecosystem, while humans live in tribal societies with varying levels of technology. Follow Aloy, a young huntress of the Nora tribe, as she uncovers the mystery of the Old Ones and fights to prevent a recurring extinction-level threat from destroying all life on Earth.
