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 mid-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.”

The Rogue Update

The time has come, and the Rogue is here! She is charming, she is funny, she is deadly with the bow and wit. Voiced by insanely talented Rachael Messer she is ready to end the Archdemon.

Arrow and dagger
Of course, her core mechanic differs from pushy Warrior's and bookish Mage's playstyles. She uses her trustworthy bow for the main attack and has an impressive range. She can hit anything she sees (and sometimes stuff she doesn't see so careful there unless you don't mind angry goats charging at you from shadows with arrows sticking from their bottoms).

However, as always, there is a fine print here. Her arrows, unlike Mage's bolts, do collide with monsters other than the intended target. This means that picking the remote target in a melee can be tricky. Until she finds a card that makes her arrows pierce enemies and split... But that's a different story.

And since we are on the topic of melee. Bows are useless in close range, which is why Rogue switches to dagger when an enemy gets close and personal. Once it gets to this, things are probably going pretty bad, but she has a few neat tricks just for such an occasion.

Speaking from a strictly gameplay point of view, when at least one enemy gets into melee range the bow becomes unusable and Rogue switches to close range melee attacks. The melee mode is indicated by the red circle around the Rogue. Until it's empty of monsters, the bow is off the table. It's worth mentioning though, that some cards have special effects on monsters in melee range so sometimes it might be worth intentionally getting close and personal with a zombie.

Those of you who helped us in debugging and polishing her on the test branch will be happy to know that there are new spell effects in this update so there is a reason for you to check her out again :-) Most of your feedback that was not yet addressed in recent smaller updates got addressed in this update. Thank you for bravely facing bugs and imbalances, without your help we couldn't have polished her to the current state

What now, eh?
With this addition of the final hero to our party, we can begin our march toward the launch. We will be regularly checking off things from the roadmap and we will be more active in the marketing department reaching out to media and new players with each update. Can't wait but it has to be done if we want to generate buzz for launch. Anyway, it's time to talk about the roadmap.

The Final shape of the Roadmap

Below are the content updates that we are planning before the launch. At this point we are freezing feature list, meaning that our urge to include new features will have to be kept under control. Without doing so we wouldn't be able to have more or less fixed dates for updates and plan marketing efforts accordingly.

Now for the roadmap itself. There are no dates but all this will happen more or less in that order and 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 yes, you read that right, spatial stereo sound in the dungeon (currently everything is flat center).
  • Mac Support + Minimap Update - Due to popular demand we will be adding 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 through quest levels again at higher difficulties for better rewards and an overhaul of the whole Archdemon level and fight (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.
  • 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.

There are other minor mechanics and additions that we will distribute among the bigger updates but those are the most important things. And, of course, the updates are not going to stop with the release of the game.

“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).
