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 Ultimate Doom.

The Ossuary takes the player, Corvus, to the shattered remains of a world conquered by the Serpent Riders centuries ago.
