Marvel United: Maximum Carnage

Escaping from prison, Carnage partnered with Shriek and the couple started a twisted sort of “family”, bringing in Doppelganger and Demogoblin under Carnage’s symbiotic “wings”. Joined by other dark Villains like Morbius, the living vampire, these New Sinister Six pose a unified threat that will test the heroes’ resolve to the limit. Carnage poses a whole new kind of challenge, though. Spreading his infection around, the symbiote is hellbent on bringing Maximum Carnage to the world!

This expansion brings a whole new set of sinister Villains for the Heroes to face. Whether tackled on their own, or as the united New Sinister Six, each of these Villains poses a unique threat. But to bring Maximum Carnage to any of your games, this set also includes the Carnage Challenge, where Dark Carnage prowls around the game area infecting people and raising the stakes of the game. Take him out quickly, or you may find yourself facing Dark Carnage as a full-fledged Villain!
