Enormous Patch Released for Shogun 2

better AI and more maps included!

Fall of the Samurai, the expansion to Total War: Shogun 2, released earlier this week. What may have escaped your notice, however, is the huge patch that was applied on the same day. While it was considered a Fall of the Samurai patch, most of the changes/additions applied to the base Shogun 2 as well. Highlights include improved AI (and drastically reduced AI turn time) as well as a whopping 22 new battle maps! A large number of fixes and unit balance tweaks were rolled out as well.

You can check out the full patch notes below:
