It's already been announced that early access to the beta for Destiny 2 is on July 18th with the rest of the folks joining in July 21st. That said, Bungie has let loose a new trailer showcasing some of the things you'll be able to experience in the open beta.
You'll be able to play the opening cinematic as well as play with two others in an Inverted Spire Strike or battle it out in two different multiplayer modes. PlayStation 4 players get their hands on the early access beta first with the Xbox One owners coming in the day after.
Destiny 2 lands on the consoles on September 6th with PC owners being able to purchase the game on October 24th.
