The companies behind Sid Meier's Civilization 5--due on PC this fall--today (jokingly) announced the inclusion of an "extreme diplomacy" mode in the turn-based straegy game, which "would allow two world leaders to enter a death match and fight to the finish" in the event that "normal diplomacy or military might fail to resolve conflicts."

Revealed alongside this news was an "Uber Edition" of the game that includes an eight-button joystick, plus a breakdown of some attacks specific to certain leaders:

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

"Each world leader will have unique special attacks and finishing moves," explained 2K. "Two world leaders enter; one world leader leaves. The victor will obtain complete control of the challenger's world empire." More "on how to school fools in a bitter mano-a-mano duel to the death" is supposedly over on the game's official site, though it's not :(
