Wolfen-Terror is a mod for registered Wolfenstein, made by Matte Software. It was released on February 16, 2003.
It features 4 levels played in a custom EXE which features numerous coding changes. Colored floors, a new sign-on screen, the ammo box from Spear of Destiny and a handful of other changes have been made.
A fifth level is accessible, but cannot be finished.
The outline is more modern, with the only playable episode, Skyscraper Action, taking place in an office environment where terrorists have taken hostages.
A full version was never released.
