After embarking on a quest in the Sauda Mountain Pass, Ray chances upon a surprising reward — a ticket to a control AI-led special event called "The Anniversary."

Nevertheless, they strive to do their best to come out on top in this battle of champions — this cradle of elite Masters from all over the world.
