The mod features 5 new levels, all of which are quite large in size. New features include the missile launcher.
The story line is as follows:
Adolf Hitler is dead. It is over. But it is not! The terrible spirit of Evil will haunt you forever. Trapped in the dungeons of you own mind. You can never escape. But there is a way. Capture the Spear and crush the Fiend to put an end to: the NIGHTMARE.
An SDL port was released in late October 2012.
