2K Games announces plans to release new DLC for Sid Meier's Civilization V next week on October 25. They will offer a Mongols Civilization and Scenario Pack that will be free to all owners of the turn-based strategy sequel as well as sales of a Babylonian Civilization Pack for $4.99 USD which was included for free with the Civilization V Digital Deluxe Edition. Here's word on the add-ons:

The Mongols Civilization and Scenario Pack calls for the strongest leaders to ride with Genghis Khan and his Mongol horsemen to establish the largest continuous land empire ever seen. Rulers lead their civilization from humble beginnings on the steppes of Asia, until all under heaven tremble at the might of the nation.

Players can continue expanding their conquests with the Babylonian Civilization Pack as the Babylonian ruler, Nebuchadnezzar II (c. 630 – c. 561 B.C.). As King of Babylon, gamers will be able to expand their empire with advanced Babylonian Bowmen to rightfully earn the title of Nebuchadnezzar the Great.
