DUNGEON CRAWLERS! As warring global factions struggle for control of Latveria, an attack by Red Hulk traps them all together in Doom's most secret, most forbidden dungeons. Desperately searching for a path to the surface, they discover horrors Doom never intended to be found: The Eye of Khonshu. The Skull-Shaped Herb. The Hammer of Treachery. And a mutant creature so dangerous, even Charles Xavier knew it could never be set free. These forbidden discoveries breed horrors that poison alliances, pollute bodies and souls and threaten to release powers that even DOOM knew must always be hidden.
