Evil Twin

Evil Twin is a first-person psychological horror game about Lan Anh, a brilliant researcher trapped in a surreal purgatory shaped by guilt, science and madness. You explore disturbing environments, uncover clues and solve puzzles as Lan Anh confronts her past and tries to symbolically repair the damage she caused.

Lan Anh's past

Lan Anh worked at Py King Corporation, where she tested experimental cell programming on human subjects. Her mistake caused the suffering of millions. After attempting suicide, she awakens in a twisted maze of her own making.

Py King is a powerful weapons technology conglomerate that secretly funded her research. After Lan Anh disappears, the corporation repurposes her discoveries to develop destructive biological weapons. Its experiments turn the once-thriving city of Caro on Caranaires Island into a wasteland overrun by the undead.

Explore and solve puzzles

You search environments for hidden clues and solve environmental and logic-based puzzles to progress, unlock new areas and uncover memories. Rooms, objects and sounds contribute to the symbolic storytelling. Paintings and hints on walls, many generated using AI, provide visual details and cryptic clues.

An integrated in-game menu offers tutorials and guidance for solving puzzles and navigating the environment. The game saves automatically after you complete a chapter, with a banner popup to indicate this.

Release content

The Early Access version has an estimated playtime of about 2 hours; the full release is estimated at about 10 hours. In the full release, you will also be able to collect and combine items to craft tools or weapons for increasingly hostile encounters.

The story of Py King's ambitions and the consequences of its research is set to be explored in Evil Twin 2.
