Microsoft is calling for beta testers to test a new Xbox 360 system update. Participants in the program will receive a copy of Halo: Reach along with other rewards. Definitely worth giving it a shot if you can live with the beta-ness of the whole thing!

Much like we did last year, you’ll need to visit the Microsoft Connect site from this link and sign in with your Windows LIVE ID that is connected to your Xbox LIVE Gamertag. Once you complete the survey that is presented to you, the Connect site will provide program related updates and you will receive a mail once the selection process is completed.

A couple of points before you head off to register:

We’re looking for multiple thousands of participants, so your chances of making it in are good.

This opportunity is open to Xbox LIVE Members in US region only*.

To avoid any problems, read the survey carefully and double check all the information you provide.

While both Xbox LIVE Gold and Silver members can sign up, priority will be given to Gold members in the selection process.

*Due to disc distribution limitations, this beta it will be limited to residents of the United States only.
