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!
This is the manual to Heretic and it's Expansion pack Shadow Of The Serpent Riders, Scanned into PDF format and was found on Archive.org, I don't take credit for this file and I don't own it either.
This is awesome, thanks for uploading this.
