描述
Year is 2855 nearly 350 years after humans have colonized the oceans of the icy moon of Europa. Interesting designs serve as personal vehicles for its human inhabitants who wish to explore or just get around from place to place in the water. A popular design is the Octopus Submarine design. Humans normally put the Octopus vehicle on autopilot but every now and then decide to use the control interface to pilot the submarine themselves.
