Alone in the Dark: The New Nightmare (alternatively and internally known as Alone in the Dark 4) is a survival horror video game and the fourth installment and first reboot of the video game series Alone in the Dark, developed by Darkworks and published by Infogrames Entertainment, SA. The game was released in 2001 on several platforms including Windows, PlayStation, Dreamcast, and Game Boy Color. A PlayStation 2 version of the game was also released several months after and only in Europe.

The player is given the option of choosing which of the two protagonists they play as. Carnby’s side of the plot is based mainly on fighting the monsters by physical means, particularly with his trusty double barreled revolver, while Aline’s is more centered on puzzles. The two occasionally meet up, and the main areas of plot intersect.
