I'm afraid there won't be a KMOD for heretic.
But there will be a DMOD. As in D'sparil mod? and also D'sparil's Heritage. It would be cool if that was an expansion for KMOD.
And soon after that is complete it would be cool to combine the two and do DKMOD or D'sparil and Korax mod where heretic and hexen worlds fuse together. We can see centaurs and sabreclaws together as well as afrits and gargoyles. Also disciples and dark bishops fight side by side. We will also see a crossbow right beside a serpent staff. Corvus would have the ability to carry more weapons than the hexen's 3 characters.
Ya, for scattered evil, the original should be hexen. Then people can download the original or download the expansion where it features new textures, monsters, and a new class, who can hold more weapons than the other 3, called the heretic. All these things will be from heretic.
