SeaColony is a survival colony-builder set on the open sea. Build and expand a floating settlement, manage your colonists, develop production systems, and survive the challenges of life far from land. Start with limited space and resources, then gradually turn your small platform into a self-sustaining colony.

Every expansion matters as you balance food, water, power, production, storage, and the needs of your colonists. Research new technologies, establish farms and fishing systems, trade with passing merchant ships, and prepare your colony for pirate raids, fires, harsh weather, and other unexpected events.
