A simple addon for Doom, Heretic & Hexen which makes some changes to duplicate monsters (E.g Hell Knights, NitroGolems) to make them as different as their original counterparts. For Example Hell Knights have their own projectile attacks and not uses Baron's. Similar thing goes between the normal and ghost monsters in Heretic. Also made some minor fixes like the correct sound for the Chaingunner firing chaingun, lost souls exploding and revenants launching 2 homing missiles instead of 1. That's about it :)
