About the 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!
