Sega and Creative Assembly have announced the first game in their new Total War Saga franchise.

The new game is Total War Saga: Thrones of Britannia, and as the name suggests – you’ll be fighting for control over post-Viking invasion Britain. Featured above, you can view the announcement trailer for the new real-time strategy game.

Here’s the first artwork for the game:

“Our aim with Total War Sagas is to explore key flashpoints at distinct places and times in history”, said Series Director, Mike Simpson. “Unlike our era-spanning titles, we’re putting defined geographical areas under the microscope, building super-detailed campaign maps with a strong cultural focus and flavour that players can dive into. This will complement our broader-scope titles perfectly”.

Here’s a brief rundown on the game, via Sega:

It is 878 AD, and the Viking Invasion of Britain is over. The Norse warlords are firmly established, but the ambitious kings of England, Ireland, Scotland and Wales have aspirations of their own – not least the great King Alfred of Wessex. Britannia is a furnace of possibilities, from which the template for modern Britain will be forged, across the most detailed Total War campaign map ever made.

Throughout this sceptred isle, the kings of England, Scotland, Ireland and Wales sense a time of change approaching; a time of opportunity. There will be treaties. There will be war. There will be turns of fortune that become the stuff of legend, in a saga that charts the ascent of one of history’s greatest nations.

Kings will rise. One will rule.
