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 GZDoom and Zandronum engines. Warning: After you see it, it cannot be unseen!
Duke Nukem 3D-styled bloody footprints confirmed for v20.
PS: They won't last forever like in Duke 3D because this can make the game lag a lot. So, the blood puddles will "coagulate" after 30 seconds, and won't smear Doomguy's boot anymore after that.
