Total War Battles Shogun launches on the App Store today.
The PC strategy spin-off is available for the iPhone and iPad at Ł4.99/$6.99/€5.49. An Android version is coming soon, Sega said.
Shogun was designed by developer Creative Assembly's digital team from the ground up to make use of touch screen devices such as iPad. It takes "full advantage" of the new iPad's high resolution Retina display.
It features a fully-fledged campaign mode and two-player multiplayer on the same tablet device. The Total War gameplay CA is known for has been stripped down somewhat, but Battles retains the real-time nature of its big brother, and even includes unit animations lifted from the PC Shogun game.
