Maps and a shovel will help you get treasure, and a fishing rod or nets are needed to catch fish. Here you will need provisions and purified water. There are no main tasks; the player can explore the environment and set goals on his own. You can find out why the polar ice is melting, or how to earn untold riches as a lone pirate. The interface displays 9 cells where blocks, objects, weapons or tools are stored. Having obtained the required amount of materials, the user is able to build a warship, equip it with guns and update the plating.
The passage begins with the ward receiving a small ship as an inheritance, and then moves to the island. Gradually, the user recruits new crew members with their own abilities and skills. The island is divided into several biomes, and the biggest threat lies under the ice. Unlimited possibilities help to build original houses on small islands or in the water. On the way, the central character will meet robbers, pirates or other sea vessels.
