In the frozen wastelands of Cyberia, where machines and flesh have fused into something neither living nor dead, a lone wanderer named Toska searches for meaning in a world that refuses to let him die. Haunted by fragmented memories and dreams that feel too human to be his own, he drifts through a landscape of blood-stained snow, rusting titans, and chimeric horrors borne from a tormented imagination.

In a frost-bitten metropolis where machines outlast their makers, Investigator Esfir Khairova is drawn into a string of gruesome murders known as the Sweet Tooth killings. Each crime feels disturbingly familiar, as if she’s trying to find a part of herself in the killer's mysterious motivations. The deeper she delves into the case, the more she senses something fractured within herself, a dissonance between what she remembers and what she is.

Evelyn awakens in a stark, modern room with no memory of how she arrived. As she navigates the clinical, unsettling environment, she uncovers disturbing clues—a picture frame with no photograph, cryptic messages, and fragmented memories that hint at a larger conspiracy. Initially believing someone she trusts might be manipulating her, Evelyn's paranoia deepens as the room’s features subtly change and new, troubling clues appear.
