The board is a map of America, and the players are monsters bent on turning it to rubble. But there´s much more to this game, as 2-4 players use strategy to become the last monster standing while destroying everything in their paths. Pitfalls include military forces trying to control the monsters´ rampage, and points are accumulated by trampling major cities and tourist attractions. The set includes 6 colorful monster tokens, 16 "Monster Mutation" cards, and 44 plastic military units.
