Your time on Destiny's beta later this month has been refined by Bungie and Activision, who have just announced kick-off begins at 5pm on July 17th for PS4, and the 23rd for Xbox One owners, with both platforms closing their betas on July 28th. There'll be a two day downtime for maintenance on the 21st and 22nd.
If you've got either console and want in, you'll need to pre-order the game to assure beta access. Participating retailers can be found here.
Check out the trailer below.
