Prepare to see the most disturbing, sadistic and morbid manifestation of violence that you ever seen in your life. This is the definitive gameplay enhancement mod for the Zdoom, GZDoom and Skulltag engines. Warning: After you see it, it cannot be unseen!
This should be tried out by all people who love Doom. It's simply the best gameplay mod ever made and it uses the additional possibilities the modern source ports added to Doom modding. It ramps up the gore and details to levels similar to Monolith Entertainment's Blood, which is awesome and makes sense if you consider it's inspired by the great Doom Comic (google it, it's available on the internet).
It absolutely deserves to be on the top mods in Moddb.
