Book of Demons is an isometric hack and slash action role-playing created by Polish studio Thing Trunk. The game was officially released through Steam on 13 December 2018. The game was originally developed for Microsoft Windows, but the developers informed about plans to release it also on Xbox One. Book of Demons is the first installment of the Return 2 Games series that aims to bring classic hardcore genres to broader audiences. The game features an unusual art style - all elements of the game are visualised as papercuttings and pop-up book elements, and such style defines visual framework for the whole series. The game also brings some novelties to the genre - the card system which replaces equipment and skills systems typical for the genre, the Flexiscope feature which allows players to control duration of a game session and movement restricted to a path which add a tactical element to the gameplay.
