In the deepest pits of the underworld, the gates of Hell creak open.
Rivers of fire surge and shadows twist, as the Lord of the Inferno rises to claim his dominion, threatening to engulf the realm in endless torment.
Only those brave enough to descend into the abyss and face him in a final battle can hope to seal Hell’s Door forever.

One Card Dungeon: Hell’s Door is a standalone adventure that follows the same setup and rules as the base game and the M’Guf-yn Returns expansion, with some unique new features.
This expansion adds a dungeon card, a boss level dungeon card, 1 new class, 5 new item cards, and the Stone of Perdiction.
