Coming exclusively for PC this time around, 2k Games revealed some new info regarding a new Extreme Diplomacy mode for the title.

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

The screenshot above should give you a pretty good idea of what its going to be like so you shouldn't be too confused.
