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.”

Quest mastering and the new Archdemon quest!

Quest mastering!

Yes, before you ask, the golden keys are making a comeback. The number of keys you have accumulated will be readjusted to the new system when you start the game for the first time after the update. This is necessary because we have changed drop rates a bit and, as some of you might remember, there used to be a bug that would fill some dungeons with hundreds of golden chests filled with golden keys. Ah, the good old days.

But back to the mastering itself. You can now use golden keys to unlock much more difficult versions of quest boss levels to test your skill. Keep in mind that Quest Mastering levels and bosses were balanced for certain character level. If a quest proves too demanding you can always gain more levels in free play and come back later.

Defeated bosses during quest mastering drop legendary cards (assuming there are any left to be dropped of course) so it's worth a shot. Or multiple shots since some bosses are meant to be challenging on higher mastering levels.

The new Archdemon's dungeon
The old Archdemon quest left something to be desired in our opinion so we tweaked it a bit. The new one has unique challenges and bosses. The Archdemon himself learned a few new tricks as well. Not to mention that the new level has significantly more ducks than it used to!

And once we add all the new voiceovers it will truly shine!

In other news
We fixed a number of bugs in this release, among them the double attacks the hero performed when clicking on a shield. That resulted in shields being much easier to crush. I wonder why no one reported that one :archduck:

We are now working on adding all the new sounds to the game and post-processing and adding the new voiceovers that our super talented voice actors recorded for us. Once we are done you will hear a lot more one-liners (and situational comments) from our heroes bosses and townsfolk.

Last but not least, an option was added to disable auto attack by changing a value in the custom settings file. If anyone is interested in that hop into forums for more details!

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.

“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).
