Four factions have grown and their boundaries widened. The conflict is not to be averted. Blood will soon be shed. Mutants Union is the power that made rocks roll and attack, and the other factions responded quickly. The New Era begins, the era of war...

The New Era, a standalone expansion for 51st State, contains more than 80 new cards and a new, fifth faction – The Hegemony, a violent band of criminals. New rules for direct interaction allow players to invade each other and sign deals with opponents' locations.

New options and decisions have been opened for players. The game is aggressive and even more engaging than 51st State. This is a whole new adventure in the post-apocolyptic world of Neuroshima.
