If you happen to live in the United States and aren't keen about waiting for them to be shipped across the Atlantic...you can also purchase them from Warsenal.
In my opinion, the synergy between all of these companies (and there are more than just Warsenal and Antenocitis Workshop) has helped strengthen Infinity. It isn't enough to have good looking miniatures and a strong set of rules. You need to have a visual impact with the scenery on the game board. Corvus Belli has made alliances with a range of companies that are pushing the design envelope and producing great products. Which is why Infinity is showing such great growth and not just in Europe.
