Overview System Requirements


Book of Adventum is quirky, old skool, atmospheric and compelling FPS adventure, which throws you in the middle of a conflict on a remote island. Discover a story of deep philosophical meaning or dual-wield your way through the conflict. Do both. Craft potions and ammunition or make do what the surroundings provide. The choice is yours. Adventum awaits. This is the free demo version of Book of Adventum. The full game will be release in late summer 2020.
