Gruntz is available this year at the Salute wargames convention in printed copy. A limited quantity is available on the GZG (Ground Zero Games) stand.
As a show special it will be bundled with a CD-ROM which contains a PDF version of the rules and the Barracks application. So for £20 you get the full printed rules, including an electronic copy and the ability to make your own unit cards using the Barracks app.
Please pop by the GZG stand for full details.
