Robot Entertainment announced today that third-person tower defender Orcs Must Die! will be published by Microsoft Studios and available later this summer for PC and Xbox Live Arcade. The developer previously gave us a window of "late August or early September."

Orcs Must Die! will be playable this weekend at San Diego Comic-Con in the Xbox Lounge, located at the Hard Rock Hotel, and Robot Entertainment will have an OMD prequel comic book available at the show.

Not going to Comic-Con, but still want to get your hands on the transmedia companion fiction that is sure to deliver Great Gatsby nuance to the Orcs Must Die universe? Don't worry, the comic will be available in a digital format "later this summer, also at no charge."
