A thrity-three year old private eye, Edward Carnby travelled to Shadow Island to discover what exactly happened to his best friend, Charles Fiske, when Fiske was found dead on Shadow Island.

The last Abkannis witchdocotor, Edenshaw came to Shadow Island many years ago and has lived with the Morton family ever since. Edenshaw has watched over the Morton family for many years and has made it his mission to ensure that the gate to the World of Darkness is never opened. Edenshaw acts as an assistant to the player and will appear every now and again to reveal information that may or may not be necessary to the player. He plays a major role towards the end of the game.
Initially Edward assisted his brother in attempting to open the gate to the World of Darkness and made deals with Christopher Lamb in order to gain 'supplies' that he required in order to make further progress. Edward was revered by many for his work on the Abkannis tribe, though they were unaware of his methods of discovery. After a period of time, Edward realised just how terrible the things he was doing were and turned against his brother, Adam, refusing to assist him.
Each protaganist's gameplay differs in terms of the amount of action and puzzle related gameplay that the player will face with Carnby being the more action-orientated portion of the game and Aline's being more puzzle-orientated. Though the player can chose between either protaganist the stories of each of the characters both occur at the same time and interwoven together. Though there is no major difference in terms of how each character is controlled.
The New Nightmare has often been compared to the Resident Evil franchaise as it bares many resemblances such as the changing camera view as well as searching for ammo and health packs in order to survive.
Alone In The Dark: The New Nightmare was ported to the Game Boy Color by Pocket Studios and was first released in Europe alongside its console counterparts on May 18, 2001. The port was later released in America on June 25, 2001.
When Alone In The Dark: The New Nightmare was ported to the Game Boy Color the handheld could not handle the 3D environments of the game, so the 3D was abandoned in favor of 2D sprites. The Game Boy Color received a relatively faithful port of the home console game. While the home console versions could be completed in six to eight hours, the Game Boy Color port could be completed in just one.
In 2005, a film adaptation directed by infamous Uwe Boll was released based on the video game series. The movie was supposed to be a direct sequel to the fourth game in the series, Alone in the Dark: The New Nightmare, although the movie has little-to-no relation to the original trilogy of games from the 1990s. The movie contains plot elements that directly contradict those in The New Nightmare, thus it is not considered canonical. The movie was named the "Lowest-Grossing Game Based Movie" in the Guinness World Records: Gamer's Edition 2008 edition.
