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.
