Read full description
Cyan Heart is a unique “selfie-perspective” horror exploration puzzle adventure.
Guiding a girl who keeps filming herself, you’ll solve puzzles, avoid hazards, and lead her to her goal with the distinctive challenge of having no direct view of the path ahead—checking behind and below her only through the camera’s screen.
A World Dyed Cyan
Life in this world once relied on a peculiar energy called the Magenta Heart—a power that could eternally mimic any physical phenomenon.
Mimic the heat of a flame, and it would become a heat source that burned forever at a constant temperature.
Mimic a heavy blow, and it would turn into a rock drill that never stopped working.
But one day, this energy transformed into a cyan hue.
Known thereafter as “Cyan”, it remained functional yet unstable, and became a dangerous force that turned any tangible object into cyan matter.
Its influence warped both machines and living beings alike.
To the Depths of an Abandoned Facility
Rumors speak of something hidden within a facility that could halt Cyan’s spread.
Alone, the girl sets foot inside.
Due to Cyan’s “eternal” property, the seemingly deserted facility still behaves as if its long-gone occupants remain.
You must guide her through the camera, avoiding—or at times exploiting—Cyan’s mimicked phenomena, to retrieve the mysterious object said to lie at the very end.
The Recording Device "CSZ8x2"
The girl’s multi-functional camera, CSZ8x2, can record video, enable voice communication, and log data.
Pointing the camera at objects allows her to examine them or access machinery.
Hints can be received through voice transmissions from her companions.
Sometimes, looking up or down with the camera will be crucial.
Why is the girl exploring alone?
What is this thing she seeks?
And what is the true nature of Cyan?
You will discover the answers through the lens she holds.
______Witness the record she wished to leave behind.
