Our take on Deca

The defining structure is a room-by-room investigation of a dark psychiatric hospital, with scattered records and recordings gradually revealing both the setting’s secret and the protagonist’s missing past.

What is Deca?

Explore DECA, a psychiatric hospital where the protagonist wakes disoriented, injured, and unable to remember what happened.

The building is dark, corpses lie in its rooms, and unexplained sounds suggest that she is not alone. Moving through the asylum room by room, she searches for a way out while remaining under constant threat. Investigation drives the story: medical documents, audio recordings, newspaper cuttings, and other objects reveal what happened inside the facility and expose its hidden secret. The game combines horror, exploration, survival, and story discovery across an estimated 8 to 10 hours. Its central structure follows the protagonist’s gradual investigation of DECA and the circumstances surrounding her arrival.
