Creative Assembly has revealed the first campaign expansion for their grand strategy title Total War: Rome II, offering to "brings Caesar’s Gallic war to life in thrilling detail."

Titled Caesar in Gaul, the expansion will be offering a tighter scope in terms of time and geography than Rome II, the Caesar in Gaul campaign map offers an expanded, more detailed vision of Gaul and the south coast of Britannia. Players can choose from four playable factions in this conflict: the Gallic Arverni, the Germanic Suebi, the Belgic Nervii and Rome; in a campaign inspired by Caesar’s Commentarii de bello Gallico (Commentaries on the Gallic war).

“We’ve released a number of DLC packs and free content updates for Rome II, but this is our most substantial so far”, said Mike Simpson, Creative Director of the Total War series. “We’ve always planned to focus more closely on some of the key conflicts of the ancient world, and Caesar’s war in Gaul is the ideal place to start.

“We’ve also improved the game considerably since launch, and that process continues as we move onto substantial feature and gameplay improvements”. You can find more on the expansion at the official forums, or check out the screenshots below for some medieval action.

Caesar in Gaul will be available to purchase and download for PC on December 12th for $14.99.
