Open Sea Survival 3

Open Sea Survival 3 is an exciting adventure game where you have to fight for your life on a small raft in the middle of the endless ocean. You play in the middle of the sea on a small raft. Starting with a few boards, you can gradually expand and strengthen your floating base. Collect resources floating by: boards, barrels, debris, and other useful materials needed for construction. The main resources are wood, metal, canisters, and food in the form of fish. Set up fishing nets and fishing rigs to automate the collection of prey, and catch fish to maintain your strength. Be careful — dangerous sharks are always on the prowl and will periodically try to destroy your raft. Reinforce your structures and fight back to preserve your base. Explore small islands that you can dock at to collect rare resources and discover hidden treasures. Find chests, obtain valuable items, and upgrade your equipment to become more resilient to the trials of the ocean. Build a reliable, large, and safe raft, explore the sea, and prove that you can survive in the harsh conditions of the open ocean!
