Forest Escape Last Train is a surreal survival horror game in which a group of 1–4 escaped prisoners finds itself trapped in the middle of a misty forest. The distorted reality here manifests nightmares born from the fractured mind of a mad Warden, who seeks to completely break the survivors' wills and drive them insane. As they wander through an abandoned amusement park and encounter bizarre creatures made of twisted branches, the escapees gradually uncover new chapters of this grim tale. Amidst this chaotic environment, an old train requiring constant maintenance serves as their only sanctuary.
