The Blair Witch Volume I: Rustin Parr is a third person horror action game developed by Terminal Reality and released on September 30, 2000. The game reuses the same engine as Terminal Reality's previous game Nocturne. Players assume the role of Doc Holliday, a special government agent of the organization Spookhouse. Holliday is sent to Burkittsville, Maryland where she must unravel the mystery of the ancient evil that drove the hermit Rustin Parr insane enough to abduct and slay seven children. The game features fixed camera angles and controls that are similar to those in the early games in the Resident Evil series.
The game is set in the same universe as Terminal Reality's Nocturne. The secret U.S. government agency known as "Spookhouse" makes a return as well as some of its agents: Chen, the Colonel, General Biggs, and even Nocturne's protagonist, the Stranger, are all encountered during the tutorial.
In Rustin Parr, the player takes the role of female agent Doc Holliday (not to be confused with the famous Doc Holliday of western fame), who had a cameo in Nocturne. Spookhouse's primary objective is to destroy and eradicate "monsters" such as werewolves and vampires, with a secondary objective to capture and "protect" powerful arcane artifacts.
