From the publisher's website:

You no sooner set foot inside the ancient ruins than the tunnel behind you collapses. Foul laughter screeches all around you. You cannot hope to dig your way out; all you can do is search for an exit… Join forces with legendary heroes to brave the many dangers of a cavernous dungeon. Wield potent weapons and magic. Conquer hordes of vile monsters. Discover fabulous treasures. Warhammer Quest: The Adventure Card Game is a cooperative game of heroic dungeon adventures for one to four players. Players assume the roles of some of the Old World's most iconic heroes, then venture into the shadows to battle ghouls, Goblins, Skaven, giant bats, swarms of rats, and other monsters. Can you survive their relentless onslaught? Can you press deeper into their lair to find the evil villain that drives them forward? There are only two ways for your quest to end—in death or in glory!
