About The Inner Sea
The Inner Sea is a sandbox game with RPG elements set in a mysterious archipelago during the 17th century. You start with a single ship and build a fleet, hire crew, fight naval battles, take on missions and trade.
The storm and the archipelago
After a ship is sent on a mission, a violent storm catches the crew. Days of winds, rain and monstrous waves leave the ship damaged and the crew wounded and demoralized. At the storm’s eye, you discover a calm, navigable body of water surrounded by the storm: the Inner Sea. Its islands are populated by centuries’ worth of castaways from numerous cultures, and you can ally with island-born inhabitants or raid and pillage across the archipelago.
The archipelago is randomly generated, so each play-through brings a new group of islands to explore.
Sail, trade and fight
You can make lucrative trade runs, hunt for valuable resources and take on missions. Naval combat is tactical: set your ship’s route and pause the action whenever needed.
Build your fleet and crew
Capture ships from different cultures and add them to your fleet, or upgrade existing vessels to make them stronger and more fearsome. Your crew gains experience through battles and completed missions, and you can develop them into a formidable crew.
Establish a faction
Create your own faction by settling uninhabited islands. Move settlers in, build improvements and grow a small hamlet into one of the Inner Sea’s great cities.
