Halo 3 free with new 360s until December 21 [update]

[Update: The Xbox.com offer page has mysteriously disappeared, although Bungie.net has now listed some more detailed information. Apparently, the Xbox 360 must be purchased between November 21 and December 21. Hopefully the page will be back up soon.]

Hey. You there. Bought your Xbox 360 and Halo 3 yet? No? Then do we have a deal for you. Microsoft is now offering a free copy of Halo 3 to gamers who purchase an Xbox 360 by December 21. Pay attention though because this isn't a bundle and you'll have to take a few extra steps to snag your copy of Halo 3. According to the offer page, you must:

• Buy an Xbox 360 by December 21.

• Connect to Xbox LIVE.

• Register at this link with the code XBX7777, the serial number of your new Xbox 360, and a valid mailing address.

All in all, not too much work for a free game. And chances are if you've waited this long to get your Xbox 360, you were probably waiting for Halo 3 anyway. Now the only question is what to buy with the money you would have spent on it. We suggest a second controller so you can convince your significant other that games can strengthen relationships.

It occurred to us after publishing this that we should probably mention that this promotion is for the United States only.
