DOOM: Legions of Hell

DOOM: Legions of Hell is a modification for Wolfenstein 3D similar to Wolfendoom by AReyeP, only trying to more closely replicate Doom. 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. A follow up was also released in 2010 called DOOM: Legions Revisited. A similar mod exists called Klooni, which requires the original Doom II or Final Doom WAD files to run.
