Hellraiser is a mod for registered Wolfenstein, made by Mäx. Never officially finished, the mod was released as an unfinished work-in-progress version by Nexion in August 2010 on the Wolf3D Haven forum.
The mod was mentioned in the Dome news in October 2006, where it featured as an update on various projects Mäx had in progress. It was mentioned here that no progress had been made on the project since August 2005.
The mod is based on the movie of the same name, and includes quite a number of new, impressive graphics, including a brand new status bar.
Gameplay involved trickery and thought more than the standard setup of knife, pistol and automatic weapons.
The mod is currently unavailable.
