Monaco, the award-winning, long-time-coming, indie heist game from Andy Schatz will miss its launch date tomorrow on XBLA, its Facebook page reads.

"We just discovered that there is an issue which requires that we push back our Xbox Live Arcade game release date a little," the update says. "We've already submitted an update to Microsoft to fix the problem, and as soon as we know that the issue is fixed we'll have a new release date. I know our fans have been waiting a long time for the game, and hopefully they'll have the patience to wait just a little while longer. What's mine will be yours very, very soon!"

Monaco will still launch on PC via Steam tomorrow, April 24, as scheduled. Monaco won the IGF Seumas McNally Grand Prize in 2010, and we've been playing it in various stages of development in the years since. Majesco is in charge of publishing the XBLA version, while Schatz and Pocketwatch Games is self-publishing the PC - and eventually Mac - versions. This is the final day to pre-order Monaco on Steam and steal that 10 percent-off price.
