What if the Spaniards had assaulted Palace Grimaldi and taken Murat prisoner? What if the King's Dragoons had charged? Or what if the French had not used their artillery? Would their principles of Liberty, Equality and Fraternity have been better regarded? In 2 de Mayo: Assault on Palace Grimaldi, players can explore these and other possibilities, as well as six new game modes (including a double draft and customized modes) of the original game 2 de Mayo. The expansion consists of a rulebook and 44 cards: 22 new cards and the 22 original cards adapted to play the expansion.
