Kerbal Space Ocean Program
Kerbal Space Program is a game that is based entirely on its physics engine. Presented with a scale model of a Sun-like star system, the player must design and fly rockets to explore the various celestial bodies in your nearby vicinity.
The culture of the game is to see how messed up a rocket you can build and still fly it. With an incredibly satisfying explosion mechanic, most unusual crafts have already been flow. In a game about exploring nearby moons, satellites, and planets, there’s not a lot of unexplored territory out there in space.
That being said, there is one place that often goes unexplored. Much like our Earth, much more is known about the bodies of the solar system than is known about the oceans on Kerbin (the Earth analog). In the ever-hungry quest for science, I designed and piloted a submersible craft to explore the big blue.
