Today was to get on Live Arcade co-op stealth Monaco: What's Yours is Mine , but tonight the developer Pocketwatch Games announced via its Facebook page that the release had been delayed because of a problem discovered at the last moment.

The problem has already been fixed and a new version of the game was sent to Microsoft for approval, but this will result in a shift in output.

We will update when it announced the new launch date; in the meantime, to learn more about the game back to us this afternoon, when we will post our review.
