The Update

[Monsieur Alphonse]

From Steam:

The Empire: Total War™ - Elite Units of America Downloadable Content is now available on Steam. Those who've pre-purchased these elite units can simply launch Steam to automatically download the new content for use in Empire: Total War.

The Elite Units of America DLC adds 15 new elite units to the American, British and French factions of Empire: Total War. Pick up this DLC to unlock all 15 new Elite Units of America while playing the single player campaign. The Elite Units of America are also available in multiplayer and single player battle modes, when playing with the appropriate faction.

We also have new background in stead of the Warpath background. It is now blue, promoting American DLC.
