Steamscapes: Asia is the "historical Asian steampunk" setting book for the Steamscapes RPG setting (which uses Savage Worlds). This particular setting book focuses largely on "China, Japan and the Indian subcontinent" with smaller sections providing some insight on other Asian nations. Some of the new rules and content include a new profession (the Apothecary), a new racial template (the Oni), and lots of other cool things like elephant cavalry. Who doesn't want to ride an elephant into battle?
Steamscapes: Asia is currently at the tail end of its Kickstarter project with just a couple days left to go, as of this writing, and is close to meeting its funding goal.
If you would like to learn more about the project or support its funding be sure to check out its Kickstarter page.
