This was announced by a tweet from David Candland, Senior UI designer at Bungie. Here is the tweet:
Hey kids, if you want apply to beta test #Destiny, go to the source, here:http://www.bungie.net/en-us/View/bungie/userresearch/index … Elsewhere will end in heartbreak.
As evident from the tweet, there will be no third parties who would be handing out beta test invites. Keep in mind that alpha testing of the game has been going for quite some time now by select non-Bungie persons.
Destiny is set to release on PS3, Xbox 360 and the PS4. No confirmation has been given regarding the release of the game on Microsoft’s next-gen console. Right now, there is no confirmed date for the release as well.
