Recent rumblings from the Creative Assembly mod summit suggested that a Shogun 2 Steam Workshop and mod tools were on the way, and now they're here! You can peruse the Shogun 2 section of the Steam Workshop to download new maps and mods right now.
On the TWCenter forums CA announce the arrival of the Total War Assembly Kit. This contains a collection of extremely useful programs for modders, including a unit editor and a campaign map reprocessor that allows for the creation of custom campaigns.
The Shogun 2 map editor has also been updated to allow users to create historical battles. The package is capped off with the launch of the Total War wiki , which will serve as a hub for information on the Assembly Kit, as well as more general Total War info.
That should tide us over nicely until Rome 2 arrives next year. You can watch the first in-game footage of the Creative Assembly's next big game while your Shogun 2 maps download. There's a massive Total War sale on Steam this weekend to celebrate. Rome is available for just one pound. ONE POUND.
