At the Sony PlayStation 4 launch event, Bungie announced that the Destiny beta will be available first on the PS4 and PS3. According to the developers, fans who pre-order Destiny at participating retailers worldwide will receive their Beta redemption code while supplies last.
Upon pre-ordering the game at a participating retailer (like Amazon, link below) players will need to visit http://bungie.net/beta and follow the instructions on the page to secure their spot in the Beta. The required 9-digit entry code will be printed on their receipt or on a flyer distributed at time of purchase, or sent via email through their respective retail rewards program. Fans that pre-ordered before October 1, 2013 and qualify for this offer are automatically entered into the Beta and will receive their entry code from their retailer via email. All questions or concerns related to the Beta code should be brought to the attention of the retailer.
The Destiny Beta will include a diverse sampling of major activities in the full game, and will begin in 2014 on all four announced platforms: PlayStation 4, PlayStation 3, Xbox One and Xbox 360.
