The Adventure Chest is a brand-new expansion to Lost Ruins of Arnak that features an original storage solution designed by CGE and fits all previously released Lost Ruins of Arnak content. The Adventure Chest box is bigger and sturdier than that of the base game—and it still fits into a certain board-gamer-favourite Swedish-made shelf. The insert itself is made of 8 individual boxes from layered PET material and is designed to make setup, play, and clean-up as easy as possible.
