Bring 'em on!'Each boxed set includes 18 random dice (3 rare, 6 uncommon, and 9 common), plus full-color cards representing street sections, cut-out counters and a rulebook. This expandable game lets you pit the X-Men against their most famous enemies using dice to represent the various mutants and non-mutants. Each die contains symbols representing the powers and strength of each attack. - BoardGameGeek
