The XBLA launch of award-winning co-op heist title Monaco: What's Yours Is Mine has been delayed after the dev team encountered a bug in the game.

The 2010 Independent Games Festival Grand Prize winner was due to hit Xbox Live Arcade tomorrow .

“We just discovered that there is an issue which requires that we push back our Xbox Live arcade game release date a little,” wrote developer Pocketwatch Games on Monaco’s official Facebook page.

“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: What's Yours Is Mine will still be available on Steam from tomorrow.
