Posted by on

With the newest update we are introducing our streaming integration for both Twitch and Mixer, thus answering the age-old question: what is best in life? Apparently to crush your streamers, see them driven before you, and to hear the lamentations of their women!

Or, optionally, helping them overcome hordes of monsters and those who would rather see them fail by spawning drops and picking better cards!

In this streaming mode, it’s the viewer, who decides what will happen next,
so go and engage your viewers in the stream even more!


In a few words, Book of Demons is a Hack & slash game distilled to its purest form. Slay the armies of darkness in the dungeons below the Old Cathedral and save the terror-stricken Paperverse from the clutches of the Archdemon himself.

The game is available for both MAC and Windows.

Here are 21 facts about the game:

Try the free and lengthy demo of the game!


When you stream Book of Demons and use our free Dungeons & Streamers DLC, your viewers (or you - the viewer) will be able to take part in the game via chat commands on Twitch and handy buttons on Mixer using Sparks.

What can be done? In fact, a lot:

  • Steal drops like gold, card charges or even cards!
  • Spawn new cards and charges
  • Spawn an extra monster or even mini-boss and the new monster will be named after you for everyone to see
  • Attack monsters alongside the streamer
  • Harm the streamer by surrounding the streamer’s hero with ice, poisoning them or giving them mouse cursor a little nudge in a critical moment
  • Help the streamer by triggering Death Rage, granting invincibility or healing the streamer
  • Lure nearby monsters to gang up on the unsuspecting hero
  • When a legendary card is identified in this mode, voting takes place. The streamer will receive the top voted legendary card. Make sure it’s Town Portal if you want to make their day!

All actions are displayed in the game so both other viewers and the streamer will know who was that guy who just stole his gold!

We also had a few secret commands during testing, some of them crashing streamers PC but these got disabled in the final build. Or were they? No, they totally got disabled.

You can see the full list of commands and features on the DLC’s page:


Ideally on your favorite streamer’s channel – ask them to play the game and spread the word!

We are on the last stretch before the launch, which is why we are releasing the streaming integration now. Getting more people to know about the game and Early Access exit is more important now than ever.

Testing of new cards is progressing nicely, we already fixed a ton of bugs. Some bugs in the old cards also came to light thanks to dedicated testers (cheers!).

As always,
Stream safe in the paper dungeons!
