Raft

Raft begins as small as a survival game can — a few planks of wreckage, an improvised hook, an empty horizon in every direction and a shark already circling. You wake up alone on open water with no land in sight, and the first hour is mostly about not dying of thirst while hauling enough driftwood and barrels out of the current to build something that won't sink the next time the swell picks up.

From that minimal start the game opens into a long survival-craft loop. The hook catches anything that floats past, the research table converts collected materials into new buildable items, and gradually a wreck becomes a multi-storey raft with crop plots, animal pens, water purifiers, weapons, kitchens and sails. Resources stay deliberately scarce, which means every dive to scavenge reefs and every detour to a half-submerged island is a real decision rather than a checklist.

The shark is the most famous antagonist but not the only one — later destinations layer human and creature threats over the survival baseline, and a story thread about what happened to the previous inhabitants of the world's drowned remnants runs through them. The whole game supports drop-in online co-op for up to four players, and a lot of the late-game content scales noticeably better with a crew that can split between sailing, cooking and defending the raft when something large decides to climb aboard.
