Well, it's out. I bought a copy yesterday even though I have a subscription since a subscription means you get it two and a half weeks late. Boo! So, interesting elements include ... the return of Cerberus from StarCraft: Loomings, which the comic is calling the new Cerberus Program. As Chris Metzen alluded to in StarCraft Legacy's exclusive Lore Q&A, the squad did survive the destruction of the Confederacy. I don't want to give a massive plot spoiler (unless people beg, that is) but if anyone has questions, you can ask in this thread.
I was looking at the wiki and saw this: "referred to as xenomorphs." hehe cool that with Alien reference.
