Resistant is a mod for registered Wolfenstein, made by Warthower. It was released on June 18, 2008.
A bug fix update was released two weeks after this, featuring more ammo.
It features 13 new levels and several new graphics, depicting a Gothic, gory and sometimes profanity-laden scenery. Two different guards in monk attire are featured, as well as actors from DOOM and the scientist first seen in Western Wall I.
