Electrifying Bosses Update

They say that "Archdemon never sleeps"... and neither do we! It appears that recent storms over the Paperverse electrified some things. Today's update introduces new enemies you haven't the opportunity to meet before:

Electric bosses
They might seem quite harmless at distance, but don't give them a chance to come close. Every time an electric boss is hit the damage you deal them converts to ball lightning that flies your way.

Better have your Boots card polished and shiny as it might be a good idea to be well grounded in the near future!

In other news
As usual, the update also introduces a bunch of fixes. You will find the full changelog below. Those of you who enjoy hunting for achievements will be happy to hear that "I'm Invincible" achievement requirements were lowered from 10 deaths to 8 in Roguelike mode.

Another noteworthy change: Legendary Chaotic Ring effect got significantly buffed.

Besides that, we are busy planning future updates for Book of Demons and production of the next games. We are also expanding the team and switching offices (our lovely current spot is scheduled for demolition so it makes sense to plan ahead and not to be blindsided by a wrecking ball :paperdeath:). All this in hands of just seven people so it's busy as usual :archduck:

Changelog for version 1.00.18135 13th March 2019
  • Added bosses with a new tag Electric
  • Fixed a crash occurring when Twitch viewers type a dungeon command during a legendary card voting
  • Changed incorrect text on a death screen after death during quest mastering
  • Reduced number of resurrections needed to unlock the 3rd level of achievement "Tis' but a scratch"
  • Fixed Evil warrior, Evil rogue and Evil mage taunting with an empty text
  • Adjusted a change of light intensity during a Meteor fall in a dungeon
  • Changed Instigator's (legendary Chaotic Ring) effect's trigger chance from incorrect 0.1-2% to 3/5/7%
  • Removed the "Online Battle" button from Selection Screen - the feature may come back sometime in the future
  • Fixed game freezing when trying to load corrupted save file
  • Minor UI corrections
  • Added new supporters to credits

As always,
Stay safe in the dungeons :archduck:

Online Battles event summary!

Online Battles timed event has ended on schedule and we would like to take a moment to sum it up.

First of all: it worked! This was not granted as it was a very experimental networking code, something we never did before. Besides some matchmaking issues, the mode ran smoothly, which we count as a success. We also gathered a lot of useful data on network loads and general multiplayer design. Both will come in handy when working on future games in the Return 2 Games series.

While the scoring, like the whole event, was experimental and should be taken with a pinch of salt the results are in!

Over 1000 players competed with three players getting ahead of the pack:
  • kenzos75 with 15 won matches and only one match lost,
  • Lokken with 10 matches won and
  • our teammate Wiedźma Danaien who, to our surprise, played the mode a lot and won 7 battles.
Congratulations everyone, it was fun! And in case you were wondering why so many hearts for the header animation for this news: Happy Valentine's Day everyone! :paperheart: :paperheart: :paperheart:

Stay safe in paper dungeons :archduck:

“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 a Hack & Slash Deck-building hybrid in which YOU decide the length of quests. Wield magic cards instead of weapons and slay the armies of darkness in the dungeons below the Old Cathedral. Save the terror-stricken Paperverse from the clutches of the Archdemon himself!

Procedurally Generated Dungeons

Dungeons & Streamers - Twitch and Mixer integration
Monthly and all-time Leaderboards, 200+ Achievements

Book of Demons is the first installment of Return 2 Games - a series of original mid-core titles, inspired by the early golden days of PC gaming.

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.
