Book of Demons is an upcoming, deck-building hack and slash adventure, where it's the player who decides the length of quests. 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.

It's you who 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 always 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, not without good reason).

We are happy to introduce Rogue class which is now available to everyone, after intense testing phase on our Test branch. Now you can use your cunning to mischief and subdue your foes with the variety of new skills, items, and artifacts!

Rogue - the core cards

The Rogue is smart, tricky and very, very deadly... They say that she has sharpened her Claws on the need of valued fermented blood (known aphrodisiac), precious lost souls and beautiful goat skins. Using only a knife and a bow she wreaks havoc upon armies of hell.

See it for yourself!

Rogue's core mechanic differs from pushy Warrior’s and bookish Mage’s playstyles. Her bow has an impressive range allowing her to shoot any enemy in her range of sight and even beyond it! Her arrows, unlike Mage's magic missiles, do collide with monsters other than the intended target. This means that picking the remote target in a melee can be tricky. But the Rogue has many arrows in her Quiver...

Rogue - Fire Arrow (legendary card)

When approached directly, she switches to a dangerous melee weapon and then attacks those in close range. Even encircled she has an ace up her sleeve!

Rogue is switching from ranged to melee fighting style

The new class comes along with 16 totally new cards (and even more their variants). You can now shoot powerful magic arrows that will burn, freeze, poison your enemies or even auto-aim them with Epic Arrows. To support her unique fighting style you will be able to use 5 new artifact cards and 7 unique and mostly offensive spells which will split your arrows, spread confusion and bring destruction upon your foes!

Do not hesitate and try the new class now! <3

So... What now?

What's now? The Roadmap!

With the addition of the final hero to our party, we can begin our march toward the launch, so this is the right time to talk about the roadmap. There are no dates but all this will happen more or less in the order presented below. We are planning to exit early access in the second half of 2018.

  • Rogue Live
    We are here!
  • Cursed Sarcophagi & Spatial Sound Update
    A special kind of Sarcophagi for those who dare take the risk and spatial stereo sound in the dungeon (currently everything is "flat center").
  • Mac Support & Minimap Update
    We will be adding a minimap and the update will come at the same time as Mac support
  • Quest Mastering & Archdemon Fight
    This one will include the ability to use golden keys to fight main bosses again at higher difficulties for better rewards (extra duck included).
  • Tobii Support + Speedrun to Cook Update
    Ever wanted to play Book of Demons with your gaze? With Tobii Eyetracker you will be able to. Plus a new mode and leaderboard are coming in that update - how fast can you get to the first boss?
  • Challenge Mode Update
    Generate custom levels and challenge your friends to beat them in an offline competitive mode!
  • Sounds + Languages Update
    This update will include all remaining sounds in the game. We will also proofread and include community translations into the game at this point.
  • Twitch Mode Update
    Tools for viewers to kill or at least shower in crap their favorite streamer during Book of Demons stream.
  • Launch Day Update
    New cards. As always we plan to go with quality over quantity so expect a couple of new cards meshing nicely with pre-existing mechanics.

Of course, other minor mechanics and additions not mentioned here are also planned but we will distribute them with the bigger updates. What is more, the updates are not going to stop with the release of the game ;-)

Supporter's Bundle

As a side note and due to popular demand, we have introduced Supporter's Bundle also on Steam. But what does it really mean?
