The game is out in the UK but the rules aren't up yet on this site.
When are the rules going to be posted?
Really? You mean you've seen it being sold in UK?
Spirit Games in Burton on Trent is listing this as "in stock" - I assume it's the same game- has the same title, designer, year and similar looking artwork from the small picture on their website.
IGUK have had it in stock for a couple of weeks now, and my FLGS had three copies, which all sold quickly.
