Can someone please tell me why you need Gold membership to access it on your Xbox.
Because they want money.
You are limited to certain features as a free member, Halo Waypoint is a gold exclusive app, that’s why it is Gold req.
It is one of the many benefits of having Xbox Live gold and is an app on the Xbox Live app store. I think they should seriously reduce the price to people who just want to play online and join Xbox Live parties though.
