2K Games today announced a new game mode that will be included in the upcoming "Civilization V" sequel called Extreme Diplomacy, which allows two world leaders to enter a death match fight if normal diplomacy fails. Two world leaders enter; one world leader leaves. The victor will obtain complete control of the challenger's world empire. An Uber Edition of Sid Meier’s Civilization V will include an optional eight-button joystick to bring the classic fighting arcade game feel to these Extreme Diplomacy battles. Additionally, each world leader will have unique special attacks and finishing moves, including: George Washington's Uncle Slam Attack Oda Nobunaga's Tsunami Train Attack Otto von Bismarck's Hurricane Helmet Spike Attack Ramesses II's Phalanx of the Leopard Army Montezuma's Revenge of the Aztec Army Napoleon's Complex Military Strike In addition to the introduction of hexagon tiles allowing for deeper strategy, more realistic gameplay and stunning organic landscapes for players to explore as they expand their empire, Extreme Diplomacy gives Sid Meier’s Civilization V players yet another way to take over empires and conquer the world.
