Book of Demons

Even Paper Can be Dangerous in Book of Demons, Available Now on Xbox One


  • Book of Demons is a hack ‘n’ slash deck-building hybrid, releasing now on Xbox One!
  • Tailored sessions that respect your time thanks to the Flexiscope.
  • Classes, cards, and papercrafts all together in a content rich paper world.

I still remember the first time I visited Thing Trunk studio in Warsaw. Their office was weirdly located close to an Italian language school, and for me, just landing from Milan, that was a pretty weird coincidence!

The studio was like the game, full of papercrafts of any form and shape, with the archdemon from the book prominently displayed in it. As soon as I saw this, I just knew this was the right project!

The power of the Flexiscope

Book of Demons is a love letter to old school hack ‘n’ slash RPGs. With updated mechanics and quality of life improvements that make every playthrough a real joy. You are always making a step toward the bottom of the dungeon.

One of the most enjoyable parts of the game is the fact that it respects the players’ time, without compromising or simplifying anything at all. It is pure hack ‘n’ slash fun, that you can play at your own pace. That’s the power of the Flexiscope!

Demons in lie the details

Book of Demons pays attention to details: the tiny footsteps on the ground, the simple but effective animations, the sound FX, the fact that every single mechanic is built on the base of the well-established hack and slash canons, and then tailored and refined to the max! Then we have the cards, which are a perfect fit for the papercraft style.

Hack and Slash galore

Players that decide to take an adventure in Book of Demons will get access to three classes (Warrior, Mage, and Rogue, each unlocked through gameplay), more than 60 cards/powers with class exclusives and bundles of monsters to cut through!

Book of Demons

It includes different difficulty levels including Roguelike mode which offers another level of challenge with permadeath, restricted healing and even more obstacles to overcome, to the extent that the playing experience is quite different from the main game!

Don’t get the wrong impression from the very first few levels, the game starts easy, but as you dig into the depth of the dungeon you’ll find out that you need to approach groups of enemies carefully, focusing on the right foes and using the right powers to get rid of them, or you’ll get overwhelmed by those innocuous-looking piece of papers!

It took more than a year to bring Book of Demons to Xbox One and now that we are at the end of our journey, it is time to start yours and save the terror-stricken Paperverse from the clutches of the Archdemon himself!

Book of Demons is a Hack & Slash Deck-building hybrid in which you decide the length of quests. Wield magic cards and slay the armies of darkness in the Old Cathedral dungeons. Save the terror-stricken Paperverse from the clutches of the Archdemon ! Cards and Deckbuilding – It’s not a card game, but items, spells, and skills are all expressed as cards. The strategy lies in adapting your hand to each situation. Cards can be upgraded with runes and you can find many variants with diverse bonuses. Legendaries are the most epic but hard to acquire. Tailored sessions with Flexiscope – Book of Demons respects your time. It features the Flexiscope engine which allows you to divide the game into sessions of any size. It even learns your pace of gaming and predicts the time to complete the next session. Unique Mechanics – Simplified movement and fight mechanics is where Book of Demons differs the most from other hack & slash games. There is often not enough time to click-remove all of the obstacles such as monster shields, enemy spells, poison, or knocked cards, so timing, card selection and order of execution are critical. "Hack & Slash in the world of Paperverse – Book of Demons takes place in Paperverse, a world that exists entirely inside a pop-up book. It’s a tale of good and evil about saving the world from the ultimate devilry. Sounds familiar? Inspired by the dark and gloomy atmosphere of the first Diablo game, Book of Demons is part tribute part parody of hack & slash classics." " Comfort of Gameplay – Many Book of Demons features were designed with gameplay comfort in mind. Points of interest are marked at the top of the screen and get revealed once you get closer. Your character leaves footprints, which can be used to track your way back or notice paths already visited without opening the map." Challenging Endgame – On average it takes about 10 hours to complete the campaign with a single class, but maxing out a character and mastering all of the higher Freeplay difficulty levels and Quests takes much longer. The Roguelike mode offers another level of challenge with permadeath, restricted healing and even more obstacles to overcome.
