Evil Twin
SteamEvil Twin is a first-person psychological horror game that plunges players into a surreal purgatory shaped by guilt, science, and madness. You’ll explore a haunting world filled with cryptic puzzles, eerie environments, and symbolic storytelling — all from the perspective of a brilliant scientist trapped in her own mind.
Lan Anh, a gifted researcher at Py King Corporation, made a devastating mistake by testing experimental cell programming on human subjects. Her actions led to the suffering of millions. After attempting suicide, she awakens in a twisted, nightmarish maze — a purgatory of her own making — where she must confront her guilt and symbolically repair the damage she caused.
Py King is a powerful weapons technology conglomerate that secretly funded Lan Anh’s research. After her disappearance, the corporation repurposed her discoveries to develop highly destructive biological weapons. Their experiments spiraled out of control, turning the once-thriving city of Caro on Caranaires Island into a wasteland overrun by the undead.
This dark chapter of the story will be fully explored in the upcoming sequel, Evil Twin 2, where players will uncover the truth behind Py King’s ambitions and the consequences of unchecked scientific power.
Explore disturbing environments, uncover hidden clues, and solve environmental puzzles to progress. The game emphasizes atmosphere, tension, and psychological depth. In the full release, players will also be able to craft weapons from collected items to survive increasingly hostile encounters.
To enhance the surreal and unsettling atmosphere, many of the paintings and wall hints scattered throughout the game are generated using AI. These artworks serve both as visual storytelling and cryptic clues, adding a layer of mystery and unease to every room.
A fully integrated in-game menu provides players with detailed tutorials and guidance throughout the experience. Whether you're solving puzzles or navigating the environment, helpful prompts and instructions will ensure you never feel lost.
