You can also subscribe directly from DC for $23.99 for 12 issues, over at their page. There's some interesting concept art and some more cover images over there as well. And for the curious, the story summary of the first issue is after the jump.
When a human is found unconscious on the shores of Kalimdor, with no memory of who he is or how he arrived there, how will he survive? Enslaved by an Orc Shaman, he must fight for survival against members of both the Alliance and the Horde. Will he strike the uneasy balance with the other races he'll need to find the secrets of his past?
I probably won't be picking this one up; most tie-in comics aren't very good, and I personally don't tend to like Wildstorm's stuff. What about you guys?
