The Destiny 2 beta has recently been closed to those who had an invite, but now the open beta is available from 18:00 BST today, meaning everyone can jump into both the campaign and multiplayer segments.
The opening mission, Homecoming, shows off some cinematics from the campaign, and the multiplayer sees you take on Countdown on a map called Endless Vale. On top of that there's also a strike on Inverted Spire, and from 10:00 PT (18:00 BST) on July 23 you can also enter the social space called The Farm.
Which aspect are you going to be trying first?
