Bathyscaphe

Underwater cave exploration

Bathyscaphe is a PC submersible game about piloting a heavy craft through dark underwater caves. You use sonar to reveal a route, search for lost cargo, and carry it to the far lock.

Hazards and power

Currents and falling rock threaten the submersible, while curious predators move through the caves. Propulsion, sonar, and electric defense all draw from the same battery, so using one system leaves less power for the others.
