This is the Kickstarter Exclusive Marvel United expansion X-Men: The Horsemen of Apocalypse.  The item is new and factory sealed.

X-Men: The Horsemen of Apocalypse is an expansion for Marvel United that pits the X-Men against the might of Apocalypse and his four lieutenants.  Heroes may choose to first engage the Four Horsemen, taking them on one by one in a single epic game.  Any that are defeated is weakened for when they come to the aid of Apocalypse in the final battle against this nigh-insurmountable foe.
