Expansion for X-Men United. The greatest challenge for mutants has always been unity. Unity with humans, unity with other mutants, the various ideologies, and even the unity of the mutant heroes themselves! As the power of the malevolent Hellfire Club threatens everyone, both humans and mutants alike, Team Gold must also contend with the rivalries of other X-Men teams. This expansion adds a team of four new and celebrated heroes, an influential villain, new locations, and the revolutionary Team vs. Team mode to the game. All of these elements can be used individually or together with the other heroes, villains, locations, and challenges from the base box and other expansions to create countless different gameplay experiences. In the "Team vs. Team" mode, players split into two hero teams. Both teams must battle the villain and compete against each other to see who can inflict the most damage when he is defeated.
