Book of Adventum

Book of Adventum is an indie action-adventure FPS. The game takes place in a steam-powered world where the player assumes the role of a handyperson tasked to repair a malfunctioning beacon. Book of Adventum combines the time-honored problem solving of adventure FPS games - shooting people in the face and getting through not-so-difficult puzzles - with metaphysical ponderings, which you can happily ignore. The art style of the game takes a deep bow to the genre originators from the mid-aughts with a cartoon-esque flair. Explore every cranny and nook of the open sandbox world, and that's about 10 hours.
The soundtrack of the game includes tracks from mystical metal band KuuDelta and ambient master Cyborg See Cyborg Do.
