The Kaiyo Mission

The Kaiyo Mission is a single-player, 2D side-scrolling adventure about exploring dangerous underwater environments on ocean worlds. You pilot a submarine or control a diver, photograph alien animals, plants and artefacts, solve environmental puzzles and follow a narrated science-fiction story rooted partly in real research. The missions take place on underwater plateaus, including those of Saturn’s moon Enceladus.

Missions and exploration

The game has three mission phases, which lead you to different underwater plateaus. A tutorial level is also available. After completing the three initial phases, you unlock a bonus mission phase containing several self-contained games. Different vision modes, sound effects and music accompany the exploration and research tasks.

Story and setting

The story places humanity in an international effort to expand its knowledge through peaceful but hazardous exploration. One account describes a habitat set down on Enceladus’s seabed to support a group of up to ten divers working at depths of several hundred metres over days or weeks. Another story passage raises the mystery of an ESEL submarine that landed on Enceladus, melted through the ice, found life in the subsurface ocean and vanished, only to be found on Earth the following week.

Music and bonus games

The soundtrack uses African music in a science-fiction setting. The bonus phase also includes mini-games based on traditional games of the Basaa people.
