The One Night Trilogy is the collective title for a series of freeware indie psychological horror games developed by Dark Gaia Studios using the RPG Maker VX engine.
[5] It takes place in July 2012 and follows an amnesiac CIA agent named Colt, who awakens in a crumbling research facility infested by otherworldly monsters.
Players take control of one of two selectable protagonists (a detective, John Faraday or a writer, Sara Wickson) as they become trapped in a supposedly haunted mansion named "The Beyond" and must try to survive the night.
Eventually, the chosen protagonist discovers that the mansion was built on top of a series of old coal mines wherein a construction of extraterrestrial origin has been buried since the late Bronze Age.
The protagonist of One Night: Full Circle is Tom Hawkin, who travels to the town of Stillwater to search for a missing relative, only to find it abandoned and infested with monsters and shadow people.
In the course of exploring the town, Tom and Colt learn that following their defeat at the end of the second game, the shadow people left "The Beyond" behind to find other ways to regain their lost power.
Full Circle covers the shadow people's final attempt to control humanity and, depending on decisions made by the player during the game, they either succeed or fail in one of two different endings.
[8] An earlier version of the game also appeared in the magazine in February 2011, where it was commended for "turning survival horror into something that can be idly enjoyed in the afternoon", though with criticism given to its writing a narrative.
