Sid Meier's Civilization 5 is set to expand later this month with two new downloadable packs. The turn-based strategy game will toss you into a hexagon with Genghis Khan in the "Mongols Civilization and Scenario Pack," which sees you unfurling his Asian empire across the globe. The pack is due on October 25th and comes, according to 2K Games, as a free "gift to the legions of Civ fanatics." (Don't mess with them, they're really well organized.)

If you'd also like to align yourself with Babylon's King Nebuchadnezzar II, you'll want to download the "Babylonian Civilization Pack," due on October 25th for $4.99. It even comes with a bit of a turn-based tongue twister: Babylonian Bowmen. Try saying it three times: "Believe Blue Babylonian Bowman Bellow!"
