Raven Software teamed up with id Software for the second time in 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.
Players took on the role of Corvus, an Elven hero whose race was nearly wiped out by the serpent rider known as D'Sparil. The first episode of Heretic was released as Shareware as a precursor to the full version of the game, Heretic: Shadow of the Serpent Riders.
Heretic won several awards for excellence and opened many new doors in the computer gaming industry for Raven Software.
