Your Xbox 360 looks fine while playing Halo 3: O.D.S.T., but what about when you stop playing and return to the dashboard? Microsoft has you covered with a mostly free premium theme.

It's a new Halo game, and to celebrate, there's a new Halo theme, featuring the sights of O.D.S.T.'s New Mombasa. It's yours free of charge, as long as you are a paying Xbox Live Gold subscriber. Behold the official description:

ODSTs aren't the only ones getting their hands on upgraded gear to prepare for the upcoming Firefight. Available only for a limited time and free of charge for Xbox LIVE Gold Subscribers, this expertly crafted Halo 3: ODST Premium Theme will get your Xbox 360 ready for a combat drop into the city of New Mombasa.

The free O.D.S.T. theme is now available for download, either on your 360 itself, or the lazy way.
