Three months after its release, 9FingerGames’ bullet hell strategy game Heretic’s Fork has its first DLC available now in the form of a collaboration with metal band Disturbed with “Inside the Fire”. That’s alongside a Christmas update that adds new character variants, gameplay cards and more. Plus, seeing as it’s that time of year, Heretic’s Fork is also enjoying a 20% discount until January 4th.

The DLC includes 7 exclusive character variants and 4 instrumental tracks from Disturbed’s 2007 album “Indestructible”. And like the base game, Inside the Fire also has a Steam sale discount on right now.

As for the Christmas update, Heretic’s Fork receives four new character variants, seven new cards, and new challenges. The update includes an enhanced music player loaded with new tracks from Rotting Christ, Sakis Tolis, and 12 new tracks courtesy of Running With Scissors’ POSTAL Redux. That’s on top of the updated gameplay for the Grizzy character, new character variants (unlocked via the new challenges), and various gameplay tweaks.

In case you missed it the first time, Heretic’s Fork is available now on Steam, and is a tower defense game with deckbuilding mechanics. Players are tasked with navigating through the bureaucracy of Hell as the newly appointed Hell’s Manager. That involves punishing sinners using the state-of-the-art computer system, the eponymous Heretic’s Fork, by building defense towers to hold back the swarms. You’ll be able to draw upon your deck of cards in order to effect changes to gameplay that will help you in your task.
