This is a major update of the first published version of the game 'Enceladus - The Kaiyō Mission' under development. It contains one level that represents an underwater plateau of the Saturnian moon Enceladus. The player has the mission to steer a solar-power-driven, robotic submarine and to identify and take pictures of underwater features, plants and animals.

New features include one additional mode, i.e. the night vision mode, an enhanced music soundtrack, context dependent sound effects in the vicinity of specific objects or animals, as well as a hidden mystery.
