Get instant access and start playing; get involved with this game as it develops.

What the developers have to say:

Why Early Access?

“Book of Demons has been in development for roughly three years and at this point spent over a year in the Early Access. All the core features are already in place, we’ve gathered a ton of great feedback from our close-knit community that helped us form the game to the current state. More feedback from a fresh point of view, your point, is always welcome!”

Approximately how long will this game be in Early Access?

“This will depend on the feedback from the community, but based on the current state of the game we are fairly certain that it will be ready for final release in the second half of 2018.”

How is the full version planned to differ from the Early Access version?

“The current state of the game reflects well the core features that will be present in the full version. We will now focus on bringing in planned features, polishing the gameplay, balancing and fixing the occasional bugs.”

What is the current state of the Early Access version?

“With all the core mechanics, the whole campaign, and the Freeplay mode in place the game can be played from start to end. It lacks some of the content like some skill cards or enemies, and a lot of sounds. We would also like to give it more polish improving effects and balance based on player’s feedback. We also have a detailed roadmap outlining main features that will make it into the game before launch in this thread.”

Will the game be priced differently during and after Early Access?

“We haven’t decided yet.”

How are you planning on involving the Community in your development process?

“We have added a special feedback widget to the game, so any player can send feedback any time while playing. Apart from this we frequently communicate through Twitter, Facebook and we plan to communicate even more through our Steam Community Hub, videos and development blog, to keep the players up to date. Our community is incredibly important to us and we will consider all feedback provided; please keep in mind, it will not always be possible for us to implement all suggestions or to respond to every comment individually.”

New seasonal leaderboards!

We have overhauled how the leaderboards work and just in time for the Summer Sale too!

When a Normal or Roguelike mode character finishes a level its name will be recorded in the First Death leaderboards. Additionally, there is a separate leaderboard for the Final Death of Roguelike mode characters since getting as deep as possible without dying will require a different strategy than getting as deep as possible in general.

The position in leaderboards will be updated with each death or completed flexiscope, dying is no longer necessary :paperdeath:

Seasonal Leaderboards
To make it easier to compare yourself against players playing the game right now and with the current balance we are introducing seasonal leaderboards. Each month will get a new leaderboard and all characters created in that month will compete in their own leaderboard. Once the month ends recording to that leaderboard will no longer possible.

You still have a few days to get a nice spot in this month's leaderboard :archduck:

All Time Best Leaderboards
Old style leaderboards are making a comeback, now named All Time. They work exactly as they used to before, with a separate one for Normal and Roguelike modes. All characters are recorded here additionally to being recorded in their Seasonal Leaderboard.

In other news
Turns out the Archdemon was a little bugged and shockwaves from his meteorites (or rather from the little fire elementals spawned by impacts) were dealing around 80 damage. That skill got nerfed but other got buffed a bit and he also now have critical strike ability. Thank you, everyone, for reporting that!

Icicle missiles thrown by some monsters will no longer block players path even before landing. However, they will freeze on hit.

Full Changelog
Version 0.93.16363+ 22nd June 2018
  • New seasonal leaderboards in addition to the old-school All-Time leaderboard
  • Leaderboard loading is now multithreaded, cuts refresh time by up to 70%
  • Icicle thrown by enemies won't block player's path until hitting the ground
  • Icicle missile will now freeze player on hit or create an icicle when hitting the ground

  • Archdemon now deals critical strikes as well as regular strikes

As always,
Stay safe in dungeons :archduck:

Roguelike and Casual game modes beta!


What initially started as difficulty settings eventually ended as different modes. The changes run deep, rendering Daredevil setting absolute, among other things.

Both new modes are in what we consider a beta stage. This means we will closely watch their balance and it would be super awesome if you could report any glitches you encounter via the feedback widget. We can't fix what we don't know about! Of course feel free to write down your thoughts on the new modes as well, we appreciate all the feedback we get!

But first things first. Without a further ado, let me present the new modes:

This one actually is not new, it's the mode you all know. It remains as it used to be. Characters playing this mode are eligible for the "First death" leaderboard (one on new leaderboards in a moment). Characters created in this mode can also be switched to Casual mode at any time (however, they will be recorded in the "First death" leaderboard when they are switched for the first time).

Looking for a relaxed run? Look no more. In this mode:
  • Healing is much easier with rapidly replenishing fountains
  • Fights mechanics are more forgiving and monsters less vicious
  • At any time you can switch to the Normal mode.

We heard that the game was too easy, so... In this mode:
  • Fountains do not replenish
  • Amulets work only in combat
  • Healer finally got a shred of business sense and is charging for healing in town
  • Healing, mana and rejuvenation potions cannot be charged in town
  • Switching item card variant won't refund gold for charges lost (and it will discard current charges)
  • Cards drop in a completely random order and are usable regardless of any level requirements
  • Ressurection after death costs gold and the cost increases with each death. Looks like the healer has some serious gambling debts to pay... Anyway once you run out of gold the character dies permanently and is immortalized in the "Final death" leaderboard
  • Once a rogue always a rogue - character created in this mode cannot be switched to any other mode
  • Characters eligible for "Final death" leaderboard
  • Characters eligible for "First death" leaderboard

New leaderboards, the old style Daredevil is no more
While we are keeping old leaderboards (and new scores will be uploaded there until game's launch) the Daredevil mode now will work differently. All characters playing Normal mode will have their first death recorded in the "First death leaderboard" and can continue playing afterward but won't be recorded in the leaderboards again.

Additionally, all characters playing in Roguelike mode will be recorded in the"Final death" leaderboard exclusive for Roguelike mode.

While we will be keeping all-time leaderboard data for posterity the public leaderboards will be wiped on a monthly basis.

In other news
This update changes a lot of stuff under the hood, so saved dungeons will get regenerated on the first load. Besides the new modes, there are also some quality of life changes and small fixes included. Most prominent one is cutscene skipping (including miniboss introductions), which we know many of you wanted.

  • Added two new game modes: Casual and Roguelike. Dungeons can get regenerated starting this version for the first time
  • Quality of life: cutscenes can now be skipped
  • Quality of life: the mouse can be now dragged from one monster to another's shield in order to break it
  • Quality of life: dragging the mouse over next monster will switch target after one second
  • Massive under the hood changes to the game architecture
  • Vamp Gloves card will no longer grant passive effects when disabled
  • Cold Nova will no longer grant legendary effects even before legendary variant is found

As always (and especially now in Roguelike mode)
Stay safe in dungeons :paperheart:

“Nostalgia without disappointments, frustrations and huge time investments - that’s the ambitious goal of Book of Demons, at once a parody and a tribute to the original Diablo, made in cute paper cut-out graphics.”
Rock Paper Shotgun

“Book of Demons aims to fuse the strategy and depth of Diablo with the style and charm of Paper Mario by using a unique movement and combat system, more accessible action-RPG mechanics, and a fair dose of humor intertwined with its dark theme.”
Game Informer

“Book of Demons is bound to entice newcomers to the genre as well as a long time action RPG fans who have been longing for a different kind of dungeon crawler.”

About This Game

Book of Demons is hack & slash distilled to its purest form. Devilishly charming and fun as hell. 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 the first installment of Return 2 Games - a series of original mid-core titles, inspired by the early golden days of PC gaming.

Decide the length of quests!

Have only 5 minutes for a game? No problem! Book of Demons allows you to set the length of each quest, thanks to our Flexiscope™ system. It learns your way of playing and gives you the best experience, making Book of Demons the first truly accessible hack & slash!

Build your own deck of devastating skills!

Collect powerful skill cards, combine them depending on the enemies you're facing and assemble your favorite set of devastating powers! But be warned: efficiency of each card will greatly depend on the situation you're in, so be prepared to make constant adjustments!

Relive the classic with a good laugh!

Book of Demons is a universal tale of good and evil about saving the world from total destruction and ultimate devilry! Sounds familiar? Well, how about retelling the story in a different way, with a humorous twist of a parody?

Be a part of a one-of-a-kind adventure!

Never explore the same dungeon twice - in Book of Demons every level is a procedurally generated, randomly-populated adventure of its own! You won't get bored by the diversity of monsters either - there are over 70 kinds of creatures waiting to be slain: lurking scorpions, snake archers, mad goatmen, not-so-sexy succubi... you get the idea.

Hack & slash in the world of Paperverse!

Book of Demons is indeed a dark fantasy hack & slash, but unlike other action role-playing games, it's set in the pop-up book world of Paperverse. The paper-cut universe is one of the hallmarks of Return 2 Games - a series of mid-core games, inspired by the early golden days of PC gaming. Book of Demons is the first installment of the Return 2 Games series.

Looking for even more challenge?

Slaying the Archdemon won't be the end of the story. In Book of Demons, you can master the campaign with 3 different classes (Warrior, Rogue or Mage), revisit your favorite quests in Freeplay mode or rise to the challenge and explore the dungeons on higher difficulty levels (the last one is called Massacre, with good reason).
