The first official modding tool for the Creative Assembly’s Total War series has been released today.

The editor enables modders to create their own Total War: Shogun 2 and Fall of the Samurai custom maps for use in multiplayer and versus AI.

The map editor, referred to as TEd, allows modders to alter typography and place hundreds of assets such as trees, buildings, coastal batteries, rivers, choke-points and custom deployment zones says publisher SEGA. Modders can also construct “vast and intricate castles from their component pieces”, continues the announcement.

Once a map has been created it can be used in any custom match and automatically shared with real or artificial opponents.

“Total War has enjoyed a strong and dedicated modding community down the years, and we want to do more to support that”, said SEGA’s Rob Bartholomew. “With TEd at their fingertips, we’re expecting to see new battle-maps for Shogun 2 that will equal our own in popularity.”

TEd is free, and can be downloaded now by Shogun 2 and Fall of the Samurai owners via the Tools section of the Steam library.
