2K Games today announced that new downloadable add-on content for the award-winning Sid Meier’s Civilization V PC game will be available on October 25, 2010 via its digital distribution partners. As a gift to the legions of Civ fanatics, players will be able to download the new Mongols Civilization and Scenario Pack for free; and for the first time ever, purchase the Babylonian Civilization Pack for $4.99 – which was previously available exclusively as part of the Sid Meier’s Civilization V Digital Deluxe Edition.

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.

Sid Meier’s Civilization V takes this definitive strategy game series in new directions with 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. The brand new engine delivers a spectacular visual experience that brings players closer to the Civ experience than ever. Wars between empires feel massive, as armies dominate the landscape and combat is more exciting and intense than ever before, including an extensive suite of community, modding and multiplayer elements.

Sid Meier’s Civilization V is rated E10+ (Everyone 10 and older) by the ESRB and is available on the PC.
