I get asked all the time how do I get on a beta.
The answer is first go to Connect.Microsoft.com
Sign in using a Microsoft Live account, then click on the connection directory and choose the Beta that interests you. You will need to apply and once accepted you NEED to give feedback to the beta group
One area to Join is the
Microsoft Game Studios Beta Program
We want EVERYONE – not just hardcore players! Whether you play once a year or every day, whether you pre-order the latest consoles or wouldn’t think of paying for a game – we want feedback from you!
