SEGA today announced that Empire: Total War players will soon be able to extend their gameplay experience with the Empire: Total War - The Warpath add-on, scheduled for release exclusively via Steam in October.

Empire: Total War - The Warpath Campaign adds a new detailed North American campaign map to expand the Empire: Total War experience. Additionally, The Warpath Campaign also adds five brand new American Indian factions, the Iroquois, Huron, Plains, Pueblo and Cherokee tribes. The new playable factions will battle the invaders in the Warpath Campaign, and are also playable in multiplayer battles.

A new technology tree, with 18 tribal technologies, will only be available to these new factions, as well as two new agent types: the mystical Shaman and the cunning Scout. These new factions will also have their own unique Elite Units.

"To further iterate our support for Empire: Total War, we're happy to announce The Warpath Campaign," said Mike Simpson, Creative Director at the Creative Assembly. "With brand new factions, a full new campaign map to play through and changes to the technology tree, this is the definitive Empire: Total War experience."

Empire: Total War - The Warpath Campaign will be priced £5.99.
