Players who preordered the game should be receiving early access codes.
Destiny 2, similar to the original title, is receiving both Closed and Open Betas. While the test will be open for everyone on July 21st, everyone who preordered the game will start playing sooner. The time differs on each platform.
If you are a PlayStation 4 owner and you already received a key from your shop, you can download the Beta client and start playing on July 18th at 7 PM CEST. Xbox One players can download the client as well, but their access starts one day later, on July 19th. PC players will get their beta in the future, so there’s a bit of a wait here, unfortunately.
