Larry Fessenden and Graham Reznick to help ensure the game features scares.
PlayStation Move slasher title Until Dawn – revealed back at gamescom – will feature a script penned by indie horror writers Larry Fessenden (Wendigo, The Last Winter) and Graham Reznick (I Can See You), reports Polygon.
The pair have 30 years experience in the horror genre.
Supermassive Games exec producer Pete Samuels says the duo have been brought on board to ensure the game features "the scares you expect from a horror movie."
The challenge for Fessenden and Reznick is creating a seven-hour horror, when the majority of genre movies run around 90 minutes.
Until Dawn will be released in 2013.
