Heretic

Raven Software teamed up with id Software for the second time in its creation of the hit fantasy action game Heretic. Based on a modified Doom engine, Heretic pioneered a revolutionary new inventory system for character item use that has become commonplace in the FPS genre. id Software published the game under its flag and it was distributed by GT Interactive.

Players took the role of Corvus, an Elven hero whose race was nearly eliminated by a horde of evil monsters from another dimension. The first episode of Heretic was released as shareware as a precursor to the full version of the game.

Heretic won several awards for excellence, appeared in such notable publications as USA Today and Playboy, and opened many new doors in the computer gaming software industry for Raven Software and its team of developers. Heretic was Raven Software's most popular, highest acclaimed, biggest selling game to that point.

After its big success, two additional episodes were released for free, upgrading the normal Heretic to Heretic: Shadow Of The Serpent Riders.

Some of the modifications Raven made to the Doom engine for Heretic were sectors that can push the player, an inventory system, ambient sounds, translucency, and looking up and down.

Story
The world of Parthoris was populated by many peoples who divided themselves into seven great nations, as well as the mystic Sidhe elves. It was these elves who kept the Tomes of Power and the sacred candle flames which eternally burned to represent the armies of the world.

The Sidhe believed in a prophecy of Armageddon, and their prophecy ultimately proved itself true when from the east came the three terrible Serpent Riders cloaked in black. They were great sorcerers, and they demonstrated their power by quelling the wars of the eastern provinces. Soon the men of the seven nations turned to their worship and built a great temple in their honor. Upon the temple was the Sign, a crossed trident, and the worshippers came to call themselves the Order of the Sign. The deeper into reverence of the Riders' dark ways they fell, the more they were sapped of their free will and spirit. Once all of the seven realms were theirs, the two eldest Riders departed, leaving D'Sparil alone to prepare the world for destruction.

Recognizing the fulfillment of prophecy, the Sidhe refused to follow in the worship of D'Sparil and thus they were set apart from the other peoples of the world. Once sacred guardians, they were now heretics, hunted and hated everywhere they went. D'Sparil's disciples turns the minds of the seven kings toward conquest of the Sidhe realm, and when the Seven Armies marched upon them, the Sidhe Elders extinguished the sacred flames, destroying them all.

D'Sparil was enraged and in the chamber of the Elders he stirred up a storm of white-hot flame, killing them all. The earth burst open beneath their charred bodies and from within poured legions of the undead as well as murderous beasts from worlds beyond. This new army overwhelmed the Sidhe and slaughtered them in untold numbers. In only one day, their civilization was destroyed and their survivors were scattered far and wide. The darkling creatures had carried off the Tomes of Power and the other artifacts of the Sidhe as spoils of war. Left defenseless, it was surely only a matter of time before all Sidhe perished under the Order of the Triad's unyielding fury.

Most of the few remaining Sidhe hid themselves away, but Corvus was determined to have revenge. Heading east into the wilderness he came upon the City of the Damned, where the very air reeked with rot and decay and the only sounds were the screams of foul creatures seeking his blood. Armed only with his staff and Elven Wand, he had little hope to survive. So began the downfall of D'Sparil and the salvation of Parthoris.
