About the Game
Book of Demons is a Hack & Slash 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 Roguelike Mode for fans of extreme challenge 70+ different types of monsters, with different traits and custom mechanics Xbox and Steam controller support Dungeons & Streamers - Twitch and Mixer integration Monthly and all-time Leaderboards, 200+ AchievementsBook 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.

User Reviews
Amazing adaptation of that famous game. Great game to kill some time at the office while procrastinating :) Definitely made with passion. Full price/discount price it doesn't matter, you won't regret it if you're an isometric ARPG veteran
Paper version of Diablo 2 and I really like that Twitch integration.
Although characters seem to be somewhat flat it does not takes any depth from the game :) The action is solid and entertaining. Cards system is more than enough to make experience vary between playthroughs. Even though I am not a fan of dungeon crawlers the game holds a tight grip on me. It will not let me go any soon.
I really like this game! Lot of great ideas and my type of humor. Also cool achievements and avatars :)
Great game, love it so far! I definitely will be playing more.
