Hexen: Beyond Heretic - Deathkings of The Dark Citadel

Deathkings of the Dark Citadel is the official expansion pack that was released for Hexen in 1996. It features three more hubs, for a total of 20 new single player levels and a couple of deathmatch levels. Unlike the expansion pack for Heretic, it had to be purchased in retail stores or by mail order. This was unusual at the time, as most non-free expansion packs also included other new or revised gameplay elements. Also, this expansion pack did not initially include nor enable any music. Music could be fully enabled by applying a patch, specially released to address this issue (usually found online under the name "dkpatch").

The names of the expansion hubs are as follows:

• The Blight
• The Constable's Gate
• The Nave

Each of the hubs features new levels, one secret level per hub, and new puzzles based on the quest items from the original game (no new quest artifacts were added). The difficulty of the puzzles is mostly on the same level as in the original game. The overall game difficulty is slightly higher, as is typical for game expansions.

The final level of the expansion, the Dark Citadel itself, is an arena-like level, which features teleporting waves of monsters and three bosses (Fighter, Cleric, and Mage clones).
