It takes inspiration from heretic, hexen 1 and doom in some ways, and aims to fix some issues with hexen 2 as well. I based it on the Game of Tomes RPG mod for Hexen 2.
Features:
-New enemies, recreations from hexen and heretic as well as a brand new fodder berserker type
-BSP2 format which allows for very large maps (thanks to spike)
-more in depth RPG system, stats affect your damage based on your class, leveling up improves/gets you some new weapon skills
-new altfires for existing weapons
-revamped blood and gore, with lesser enemies having decapitation death animations
-full coop support with %XP loss on death and a checkpoint system
