This is a forsaken wasteland where a castle floats on the sea, surrounded by decaying factories atop a garbage dump. Strangely, nature thrives atop the garbage—lush trees and bushes, wild grasses, and untamed wildlife like wolves and raptors roam freely. The mysterious Rig people seek to claim this eerie land, battling anyone who stands in their way. Navigate the island by plane, helicopter, boat, bike, or board, and fish to survive in this forgotten, ever-changing battleground.
