Warhammer Underworlds is a deck-based strategy game of skirmish battles set in Warhammer Age of Sigmar’s Mortal Realms. It’s full of action, clever combinations and tricks, and fast-paced gameplay. You'll be able to get started right away with the four complete 32-card Rivals decks included in the box – one for The Thricefold Discord, one for Cyreni's Razors, and two universal Rivals decks for any warband. If you wish, you can even tailor your own deck using universal cards from other Warhammer Underworlds expansions for near-endless strategic depth.
