WolfenDOOM is a mod for registered Wolfenstein, made by AReyeP. It was released on November 11, 2000.
The mod takes all its imagery from DOOM and puts it in a Wolfenstein atmosphere, making for a classic nostalgia gameplay. Many sounds from the game are also featured.
It is played in an episodic flow, and mapping is of high quality.
The mod was actually made in 1996, but fixed up for proper wide release in 2000.
An SDL port was released on February 26, 2011 making it one of the earliest older mods to be ported.
In 2016, AstroCreep ported the mod to work with ECWolf, which was an extremely shitty attempt with no story screens and broken levels. In 2019, AstroCreep finally rectified this horrible mistake, re-porting the mod to ECWolf and making it completely functional as normal.
