The Ossuary

The Ossuary is an extra episode for the Heretic: Shadow of the Serpent Riders expansion. It is quite difficult and may be compared to Thy Flesh Consumed, the single extra episode for The Ultimate Doom. Like Thy Flesh Consumed, it also lacks a special intermission screen image showing the episode's map and the location of all levels. Instead, it has a background tiled with the FLOOR16 flat.

The Ossuary takes the player, Corvus, to the shattered remains of a world conquered by the Serpent Riders centuries ago. The episode, like The Stagnant Demesne, features no new monsters, weapons or graphics. There are various level themes, mainly centered on the concept of a broken and decaying world.

In addition to using the grey sky from the first episode, the Ossuary's level music list is the same with the exception of levels one and six having their songs swapped.
