Evaluation

Sunkenland has been in Early Access since August 25, 2023 and remains explicitly unfinished. Vector3 Studio has maintained a consistent cadence of major content updates throughout the game's life. The most significant recent release was Update v0.8.02 on June 27, 2026, which shipped the full Naval Combat system — including ship capture, modification, and mounted weapons — along with a 19-mission main questline, a new continent called the New World with ports, fortresses, and mountains, and numerous new locations, factions, and items. Prior to that, a full gameplay and visual overhaul launched in October 2024, and the game has received a steady stream of feature patches and bug fixes throughout. The most recent developer communication was the August 6, 2026 patch post (Update v0.8.45), which explicitly states that a Companion System is currently in development and will be released when polished. No 1.0 release date has been announced, and the developer shows no signs of winding down. The game is receiving active and ongoing development with more content confirmed to be in progress.
Evidence
Update v0.8.45 patch notes confirm a 'major new feature,' the Companion System, is currently in development and will be released when polished — the most recent developer communication as of today's date.

About this game

Sunkenland is an exciting post-apocalyptic survival and exploration game set in the near future when water covered most of the Earth. Explore sunken cities, scavenge resources and valuable technologies, build your base, trade, fight and survive.

Features

Diving

Explore the sunken skyscrapers, nuclear powerplants and subway tunnel. Gather resources, seek out lost technologies, and collect rare pre-apocalypse items. Build diving devices to assist your underwater journey. And be wary of the unknown danger awaiting you in the depths of this planet.

Base Building

Build your base anywhere you want. Will it be a water stronghold, an abandoned ship base or an island penthouse? You need it to keep yourself refreshed, craft items, farm, store items, and stay protected. With the modular building system, you can create your ideal enclave and stylize it with decorations found throughout your journey.

Base Defense

Defend your base against clans of pirates and mutants. Build high walls, barbed wire, traps, surveillance system, and artillery to keep the enemies out of your territory!

Crafting

Build everything you need, tools, weapons, a jetski, and even a helicopter. You will need different workstations and blueprints in order to craft complex items.

Survival

Gather food, hunt sharks, grow plants, and manage supplies. Make your base sustainable as resources are scarce in Sunkenland.

Vehicles

Build and upgrade many types of vehicles including sailboat, jetski and gyrocopters. They will make your exploration much more convenient.

Fighting

Fight mutants and pirates. Raid enemy atolls and steal their resources. Use melee weapons, firearms and explosives. Fight on ocean and land. Operate mounted heavy weapons to destroy enemy boats.

Trading

Trade with friendly atolls for supplies, weapons, armor and rare items. There is no universal currency, only item for item.

Co-op

Cooperate with friends and survive this oceanic apocalypse as a group. Build bases, dive, explore and fight pirates together!
