Total War Battles: Kingdom has been announced as a free-to-play strategy title by Creative Assembly’s Digital Team, which developed Total War Battles: Shogun.
The persistent-world strategy game will be playable across multiple platforms and is currently in closed beta on PC. You can register for the tester through the official website.
Here's the synopsis:
"Set during the chaotic turn of the 10th Century; the world starts to emerge from the Dark Ages divided and at war. Combining realm-building with large-scale tactical battles, players will find themselves managing the needs of their own fiefdom as they marshal formidable armies with which to duel against neighbouring kingdoms. Ultimately, players will be able to join in massed multiplayer wars against other lords in a fight for the throne. Deception, spying and outright betrayal against enemies and friends alike will see the devious player rewarded."
The game is listed as "coming soon" for Mac, PC and tablets.
