Pocketwatch Games' Monaco, an action-stealth game centered around completing heists, will be released simultaneously for Xbox Live Arcade and Steam, reports Joystiq.
Pocketwatch is currently unsure whether the Steam version will be available on both PC and Mac the same day. The XBLA version is being published through Majesco; Pocketwatch met with the company at PAX East and "the stars aligned" in regards to porting Monaco.
The developer has added four-player online cooperative play to both versions in addition to the originally planned local co-op and single player campaigns.
