The Campaign Book (released at the end of Sept) is up for pre order from Covus Belli, with a free, exclusive, miniature.
There are also a range of army sets available at a reduced cost.
Be aware that shipping costs are fairly high. You've been warned.
You may also want to keep an eye on either Beasts Of War, or the Infinity Facebook page as there are two new videos up, one dealing with the new book...
...and one dealing with the new faction, the Tohaa.
