Stacking? Publisher THQ's UK Twitter account recently confirmed that "DLC for Stacking is in development!" The tweet added, "Look out for more details on this soon," before ending with a mysterious colon immediately followed by a close parenthesis -- which can only be code for ... something. (We don't know. We're still trying to crack the intricate cipher.)
We've contacted Double Fine and THQ for more information. We'll make sure to take any info received, put it into words, put those words into a post, and then put that post into this website.
