Twenty-Four is an adventure game by John Sessoms, officially released on July 3, 2020. The game was inspired by the atmospheric horror elements of titles like Amnesia: The Dark Descent and Machine for Pigs, and it serves as a concept demo, indicating that various aspects of the game may evolve over time.

In Twenty-Four, players assume the role of Dan McCallister, a paranormal investigator searching for a missing girl named Jane. The gameplay emphasizes stealth mechanics, where players must choose to run, hide, or face dire consequences as they navigate through a dark and eerie environment.

The storyline unfolds on May 24, 1841, as Dan ventures into a foreboding forest, only to be knocked unconscious and awaken in an unknown, sinister location. The quest to uncover Jane's fate drives the narrative forward.

Twenty-Four stands out with its immersive first-person gameplay, physics-based puzzles, and a richly detailed environment powered by Unreal Engine 4, complemented by a chilling atmospheric soundtrack that enhances the horror experience.
