Xbox Live release schedule portends a return voyage to Insanely Twisted Shadow Planet. The stylish, free-floating exploration game is set to receive a new add-on, called "Insanely Twisted Shadow Planet: Shadow Hunters," on September 13.
According to comments made earlier by Fuelcell games CEO Joe Olson, the DLC introduces a "co-op experience," presumably boosting the number of simultaneous flying saucers in a single household to impending-divorce levels.
Fuelcell has confirmed neither the release date (which is subject to change), nor the listed price of 400 MS Points ($5). We'll let you know as soon as we hear more about the actual "C" in this DLC.
Update: The DLC missed Microsoft's proposed release date, and Fuelcell has not responded to our requests for comment.
