The best way is to go to the MS, click ''Play games'', and all of them are featured. Make your choice, read some helpful threads that can make your review better, and apply (just write a review of the game in the Reviewer Lane.) The recruiters will accept/deny you. Once you're accepted, you get the badge. If you're denied, the recruiters sink your review and you can re-apply on a certain date. And be sure to review a good game. Things like ''Kill Justin Bieber'' or ''Glitch to level 250'' are bad examples. Games that are featured are perfect for the job. Hope this helps.
