Marvel United: Maximum Carnage is the expansion that takes the battle against Marvel villains to a new level of chaos. The scenario introduces the New Sinister Six, composed of Carnage, Shriek, Doppelganger, Demogoblin, and Morbius, along with the dreaded Dark Carnage who roams the board infecting allies and raising the stakes. Each villain has its own action cards and unique effects, demanding that heroes coordinate well. The Hand Management mechanic forces players to carefully choose when to use attack, defense, or support cards, while the Modular Board guarantees a different layout each play‑through, keeping the challenge fresh. The expansion also adds a Solo option, letting a single player tackle the threat in a Solitaire mode with rules that maintain balanced difficulty. The game remains cooperative, supporting up to five players, and each character has Variable Player Powers that shape how they play. Additional components include detailed miniatures, villain cards, and a challenge rule set that brings Dark Carnage to life as a living threat. In short, Maximum Carnage adds more villains, more chaos, and more fun for fans of the United series who want to test their strategic skills in a high‑tension environment.
