Hexen: Beyond Heretic, released as simply Hexen for some ports, is a first-person shooter video game developed by Raven Software, published by id Software, and distributed by GT Interactive beginning on March 16, 1996. It is the sequel to 1994's Heretic, and the second game in the Serpent Riders series. The word Hexen is German for "witches".

The game received mostly very positive reviews in computer gaming magazines. There were complaints of the graphics being crude in comparison to the preceding game in the series, Heretic, but vast and well designed levels plus numerous enemies and weapons were seen as advantages.

A new series feature introduced in Hexen is the choice of character class. Players may choose to play as a fighter, cleric, or mage. Each character has unique weapons and physical characteristics, lending an additional degree of variety and replayability to the gameplay. The fighter relies mainly on melee attacks and is tougher and faster than the other characters. The cleric uses specialized weapons, some of which have limited range or healing effects. The mage uses long-range weapons, whose reach is counterbalanced by dealing relatively little damage and the fact that the mage is the most fragile of the classes.

Hexen uses a modified version of the Doom engine, which allows jumping, network play with up to 8 players and the choice of three character classes. It also popularized the "hub system" of level progression in the genre of first-person shooter games. Unlike previous games, which had relied purely on MIDI for music, Hexen is also able to play tracks from CDs. The game's own CD contained soundtrack in audio format that was exactly the same as the game's MIDI soundtrack but played through a high quality sound module. However, the most significant improvement was the addition of wall translation, rotation and level scripting.
