Finally, after much consideration, this mod is reborn with a totally new concept and aim. It is for Zdoom now; it takes after my survival Doom level, The Sewers of Death, and features more than just running blindly down some damned pitch black sewer tunnels.
Some of the levels will have endlessly spawning monsters, so you can't ever really kill everything off. Instead, this mod focuses on completing your investigation while surviving the threats you are up against.
Sinful Influx takes advantage of what used to be Doom. I've taken and adapted sprites, textures, flats, and skies from the alpha and beta versions of Doom, and added them to the mod. I've also added new monsters that extend the variety of Doom's monsters. Ghost versions of the Demons and Barons, and even a spectre-like Baron of Hell. Who knows; there might even be a real boss ;)
Although this mod may be short, it should keep you busy for a long damned time.
