Not all dwarves are nice and help out the other races of the surface world whenever they're needed. Some are deeper, darker, and have a more sadistic twist. They're the Abyssal Dwarves and if you've been waiting for them to be released for Kings of War, your wait is over. You can head over and pick up this new army now, including some new web-only bundles on Mantic's website.
From the announcement:
The wait is over! Hard plastic Abyssal Dwarf Decimators and Blacksouls are finally here, along with a whole host of amazing new Abyssal Dwarf releases for Kings of War. This army has been turning heads in the office and we think they're going to a huge release (no pun intended).
