From the update:
Available on advance order this weekend is a huge number of Citadel Finecast Space Marine miniatures. From heroes such as Librarians, Chaplains, Captains and Techmarines, to bigger units including Veteran Squads and the Legion of the Damned, there is something for every single Space Marine player. What's more there are several bitz packs to upgrade your armies, from Crimson Fists Shoulder Pads to a White Scars Bike Squad Upgrade Pack. There are even Casualties to represent when your dice rolls go badly.
