DOOM: Legions of Hell is a modification for Wolfenstein 3D similar to Wolfendoom by AReyeP, only trying to more closely replicate the original game. First released as a vanilla mod, it was later ported to the Wolf4SDL engine for better performance and compatibility; particularly in terms of rendering the game's floors, ceilings and backdrops. It was created by insurrectionman and first released on June 26, 2007, with the SDL version out on December 25, 2012.
