Microsoft is putting together a series of rare Xbox One controllers themed around some of the biggest games being released this year on the platform.
Among the games being celebrated with the new controllers are Fallout 4, Halo 5: Guardians, Rise of the Tomb Raider, Plants vs Zombies: Garden Warfare 2, Mirror's Edge Catalyst, and Rainbow Six Siege.
The controllers are being prepared for Microsoft's presence at PAX Prime, which takes place this week, where the company will be giving away seven custom controllers and Xbox One consoles.
To have a chance to win one of them, you'll have to attend PAX Prime, take a photo, and share it on Instagram or Twitter with the hashtags #xboxsweepstakes and #xbox to be entered to win. You'll also need to follow @Xbox on Twitter. Another way to win is to retweet an official tweet referencing the controllers.
Unfortunately, that's the only way to get any one of these controllers, so you're out of luck if you aren't planning to attend the event, which runs from August 28 to 31.
