Northern Darkness is a mod for registered Wolfenstein, made by Mäx. It was released on August 19, 2007.
The mod features 25 levels spread across three episodes. The environment is influenced by black metal, and enemies are white youths in hip-hop regalia, priests, police cars and Jason-like characters in hockey masks.
All of the graphics, sounds and music have been replaced, and the mod is unique in the respect that it focuses on black metal and even uses the guitar as a weapon. The protagonist is in full make-up with long, shaggy black hair which makes for an extremely atmospheric and unique gameplay.
Black metal groups alluded to in the graphics include Gorgoroth, Finntroll and 1349. The mod's title could both allude to the record company of the same name specializing in the black metal genre, as well as Finnish group Immortal's Sons of Northern Darkness.
