Deep Blue Fantasy

Deep Blue Fantasy is a roguelike strategy adventure set in an underwater world in the distant future, after the continent has sunk beneath the sea. Humans, Merfolk, Leafkin and Mechanoids live together in the depths. You play a “lucky” adventurer who sets out in a submarine, backed by a loan from the Jonathan Foundation, to explore the savage sea and repay the debt in pursuit of true freedom.

Explore and earn

You navigate procedurally generated underwater mazes, completing commissions, searching for treasure, trading goods and fighting sea monsters to build your wealth. You can explore every corner of the maze and buy goods cheaply from shops run by different races, then sell them for more in other areas. Choosing routes and cargo carefully can bring in large profits.

Crew and combat

Weapons need specific ability dice to activate, and crew members provide those dice. You choose from the weapons you encounter and assemble a crew whose abilities work together in battle. The game has 60 weapons and pieces of equipment, supporting different combinations and playstyles, as well as enemies with distinct characteristics that create varied battles at different difficulty levels.

Manage your submarine

Cargo, resources and crew condition all affect your journey. Overloading the submarine slows it down, while a shortage of resources can lower crew attributes and lead to unpredictable adverse events. Weighing these trade-offs and making choices is central to the success of an expedition.

Underwater terrain

The mazes span four types of marine terrain: plain sea, gorge sea, glacier sea and volcanic sea, each with its own landscape.
