The Horus Heresy Book 3 has a preview video up now with some great artwork, just enough to get you excited for the next big release. Great timing too, right alongside the pre-orders for the Primarch of the Luna Wolves, Horus.
Some of the artwork, like the one shown above is just breathtaking.
Here is your link to see the preview video on Youtube.
