Last Harbor — everything we know

Last Harbor overview

Last Harbor is the next big survival-craft release from tinyBuild, the studio and publisher behind Raft, Valheim, Black Skylands and Hello Neighbor. Officially revealed at Summer Game Fest on June 6, 2026, Last Harbor is an open-world multiplayer zombie survival game built on Unreal Engine 5. The premise is simple: a zombie outbreak has overrun the Pacific Northwest, and your only safe ground is a single boat drifting in the San Juan Islands.

Where most survival games give you a piece of land, Last Harbor gives you a boat — and forces you to keep it alive. Hull damage, engine failure, fires, storms and the constant threat of scavenging runs onto zombie-infested islands make every day a risk-vs-reward puzzle. The official Steam store copy captures the tone perfectly: “Zombie Apocalypse On A Boat. You're stranded on a boat during a zombie outbreak in the beautiful San Juan islands. How will you survive an open-world archipelago, where the living are just as much of a threat as the dead?”

Core mechanics

• Boat-as-base survival. Your boat is your inventory, your shelter, and your only mobile spawn. Upgrade hull, sail, engine, storage and defenses through scavenging runs.
• Open-world archipelago. Multiple islands with distinct biomes (lighthouses, fishing villages, harbors, lighthouses, wooded inlets) that you can sail to and loot.
• Zombie variants. Different infected types visible in the reveal trailer — including what appear to be runners, brutes, and swimmer-class zombies that can board you at sea.
• Crafting & repair. Build weapons, traps, medical items, fortifications and boat parts. Repair hull damage and refuel engines from salvaged materials.
• Online Co-op & PvP. Crew up with friends on a shared boat, or play on hostile servers where other players are the real threat.
• Hunger, thirst, fatigue, exposure. Classic survival-craft stats layered on top of a maritime weather system (rain, fog, storms, night cycles).

Setting & story

The Last Harbor archipelago is a fictionalized version of the real San Juan Islands in Washington State — a cold, foggy, pine-covered chain near the Canadian border. The setting is deliberate: open water, narrow channels, and dozens of small islands create natural choke points for combat and navigation. The story, as described by tinyBuild, is told mostly through environmental design and the occasional radio transmission from the mainland.

Platforms & languages

Last Harbor is currently announced for Windows PC via Steam (App ID 4369620). No console or Mac versions have been confirmed at the time of writing. Supported languages on the Steam store page are English, French, Italian, German and Spanish — typical of a tinyBuild production.

Last Harbor vs Raft vs Valheim

Players familiar with Raft will feel at home: a small movable base, ocean-based traversal and the constant pressure of resource depletion. Valheim fans will recognize the biome progression and boss-style progression hooks. Where Last Harbor differentiates is the zombie threat layered onto the open water — there are no other survival-craft games that combine boat navigation, island scavenging and zombie hordes in the same formula, and that combination is what tinyBuild is selling.

Reception & wishlist count

Within 24 hours of the SGF reveal, Last Harbor trended #3 on Steam's front page and accumulated an estimated 80,000+ wishlists based on third-party tracker estimates. The IGN-hosted trailer pass has crossed 114,000 views and the official tinyBuild channel sits at roughly 118,000 views. The Last Harbor wiki will keep tracking these numbers in the news section.
