H!ZONE is a level/episode pack for Hexen/Heretic. which was released by "Wizard-Works". H!ZONE provides no less than 9 full episodes (despite it's written 12) for Heretic, as well as many standalone levels that are mostly the user-made kind. All episodes are also "Wrath of Magic" compatible. The episodes are pretty hard, and a "Wrath of Magic" mod welcoming changes like the Battleaxe - will indeed make things much more possible and enjoyable. All of those episodes when activated - they replace the THIRD episode of the original Heretic. (The Dome of D'Sparil). When the new episode-wad is loaded, - just start the 3rd episode as usual and you will begin a completely new adventure.
