The first edition of the rules was published in 2009 in Miniature Wargames. The second edition was freely available on request but in early 2017 James decided to update the rules once again this time for commercial release.
There's a new web site to keep people up to date on all the pre-publication news and gossip. After publication the site will become a place for updates and for additional resources associated with the rules.
There are numerous ways to keep up to date but perhaps the easiest is to subscribe using the "Follow by email" option at the bottom of every page on the new web site. That way you will receive each post by email to read at your leisure. You remain in control and can unsubscribe at any time.
