Book Of Demons Review

The pages of the Book Of Demons come alive in the paper world of the only game that changes and molds itself to better fit into your gaming habits. Experience the innovative Flexiscope technology as you comfortably slash demons and zombies left and right in your free time like you never have before.

Introduction
Book of Demons is a Hack-and-slash game with a paper world aesthetic in which you must cut down or just blow to smithereens your way through dungeons, catacombs and eventually Hell itself to defeat the primordial evils that are killing the people of your old village. Book of Demons is a game designed to be accessible to the most casual of players while keeping the attention of veterans. Everything, from the tutorials that explain every mechanic to the game reminding you of key information to help you make the right decisions at every turn, Book of Demons is the perfect game for those who have always wanted to try out games like Diablo series but doubted their skills.

Conclusion
Book of Demons is a game created for YOU, the player. It is incredibly well thought out to be able to be played by both casual and veteran players, by those who no longer have the time to play long video games but won’t settle for mobile gaming, for the people who are just getting into gaming or who don’t have the stomach for complicated RPGs. The Flexiscope technology is something definitely see with a bright future and that I personally want to see more of, since it’s adaptability is something sorely needed in the generation of games with 30-minute-long matches.

Not content with this, Book Of Demons can be played again and again thanks to the differences between classes (as a tip, Rogues can shoot their arrows freely and from afar, making the game easier since you don’t need to be in as much danger!) and its infinite play option, where players compete to see just how far into hell the can go without dying in a game that gets harder as you keep on playing; and harder still should you choose to play in Hard, Nightmare or Massacre difficulties, where the game will ban and impose cards in your deck, as well as take away more of your gold when you die.

Score 7/10
