BOSTON–Today at PAX East, Microsoft announced a new lineup of custom Xbox One controllers based on games like Halo 5: Guardians, Battlefield Hardline, The Witcher 3: Wild Hunt, State of Decay, Evolve, Ori and the Blind Forest, and others.

To win one of the nice-looking controllers, you’ll need to attend PAX East in person this weekend, take a photo of one of the controllers (they are on display at Microsoft’s booth), and tweet to @Xbox and include #XboxOne and #XboxSweeps in your message.

Microsoft has also produced a custom Xbox One based on The Witcher 3. This system is also on display at Microsoft’s booth (we’ll upload a picture here when we get to the show floor), and the rules for winning one are similar. Take a photo with it and send a tweet to @Xbox making sure to mention #XboxWitcher3Sweeps and #XboxOne in your post.

Alternatively, you can enter by mail. Microsoft will give away ten custom controllers in all, but only one Witcher 3 console. The full contest rules are available here.

PAX East runs March 6-8 in Boston, Mass. GameSpot will be reporting from the show all weekend long.
