Delve deeper than ever before in Clank! Catacombs: Underworld!, the thrilling expansion that pushes your dungeon-crawling, deck-building adventures into a realm of even greater danger and irresistible treasure. Beneath the twisting Catacombs lies the fabled Underworld, a mysterious domain rumoured to hold immense riches, if you’re bold enough to brave what lurks in the dark.

An underground lake allows you to refine your deck, while an eager Imp Assistant can join your journey, helping you master the knowledge hidden within Secret Tomes. But fortune never comes freely, screeching harpies guard their coveted undercoins, and a fearsome Underworld Guardian watches over treasures unlike anything found above.
