Open Sea Survival 2

In Open Sea Survival 2, you start out on a tiny raft in the middle of a huge ocean. There is nothing around you except water, the occasional island, and the sound of the waves. At first the raft looks weak and unreliable, but you can turn it into a big, sturdy base. Boards, barrels, and other debris are always floating past, and that is where your shelter begins. The sea brings you useful items, and you decide what becomes the foundation of your future home. Sometimes you will see islands on the horizon, and they often hide rare resources or locked chests. The setting feels calm, but a shark is always nearby, and you have to make sure it does not tear your structure apart. Expand your base, sail to islands, collect chests, reinforce your walls, and keep an eye on whether you have enough resources to travel farther. You choose how to upgrade the raft, and your decisions determine how long it will survive. Will you manage to build everything you need before the shark attacks again?

How to play?

Throw your hook to grab everything that drifts past the raft and pull your catch on board. Use planks and barrels to expand the floor, and use debris to add new sections and strengthen the corners. Stretch fishing nets along the edges so that some resources are collected automatically. Catch fish with a fishing rod, cook it on a small stove, and watch your hunger meter so you do not run out of food.

Always watch the raft, because sharks will swim up and bite off separate pieces. Keep a weapon ready and drive them off right away, or they will take out parts of your structure. Explore the islands for plants, stones, metal, and crates. They often contain things that make survival easier, like tools, new food, and upgrade parts. Partway through Open Sea Survival 2, you unlock blueprints that let you build an oven, cover the supports, and reinforce the deck. Grow from a small platform into a real floating house, place storage boxes, and leave room for shark traps.
