With only a few days of the Destiny beta remaining, Bungie have decided to bid farewell to their “beta code” system. This means that anyone with access to a PlayStation 3, PlayStation 4, Xbox360 or Xbox One console will be able to give the games character creation, story missions, and multiplayer systems a whirl prior to its September 2014 release.
All you need to do is navigate to the digital distribution channel for your console and search for the “Destiny Beta” client. Do note however that a proper Xbox Live Gold membership is required to play on Xbox consoles while a PlayStation Plus membership will be required for the PlayStation 4 (And possibly the PlayStation 3 as well).
