Post-apocalyptic survival simulator in an open world. The game takes place in a world where, due to an accident at a research center, the planet became a victim of anomalous radiation, and most people went crazy and became mutants. The radiation spread throughout the entire planet, it drove people crazy, led to personality changes, and mutations in people and animals. Major shifts occurred in the planet's ecosystem, glaciers began to melt and cities went under water.
The main character finds himself in the open ocean on a small raft. He only has an old hook in his backpack. During the passage, players will build a shelter and a raft to explore the open world. You can also craft various devices (including weapons), as well as get food (there is hota and fishing).
