The short version is that right now, we don't have any updates for you. I know that you've heard this in various forms from me lately, but I'm going to take this opportunity to expand a little upon this. The creation of Castle Siege is, in very basic terms, collaborative. This means that any decisions made about the state of the game or updates to it, are made jointly by both parties.
I wish we could tell you more, but right now that's simply all there is to tell. All of us here at Smoking Gun Interactive & Microsoft appreciate you, our players, and the time and love you've invested in to playing the game we've created. We’re grateful that you’re on this journey with us!
