Heretic was the first game to use the Doom engine outside of id. Produced by John Romero in cooperation of Raven Software, Heretic promises to be a great fantasy blastfest in a package! Fight off Gargoyles, Golems, Wraiths and Weredragons with your Dragonclaw, Phoenix rod, Hellstaff and Firemace! This game also introduces a new item system that's become a general must for most games, using with the familiar bracket keys. Items include Wings of Wrath, Polymorph Egg, Chaos Device, Disc of Repulsion, and everyone's favorite Tome of Power, that supercharges your weapons!
The HTC was a community project aiming to make a 3 episode Heretic Megawad that would run on limit removing ports that support Heretic (i.e. Doomsday, ZDoom etc)
