Destiny 2 Beta

What you should expect:

• Homecoming: The opening mission and cinematics from Destiny 2’s Campaign.
  
• Countdown: Enter the Crucible to battle other Guardians in a brand new mode. Attack or Defend the base on a new map custom-built to support this new game type.
  
• Control: The original standard for Crucible combat is back, with some impactful changes. Control the zones on another new map built with this objective in mind.
  
• The Inverted Spire: Strike at the heart of a Vex stronghold. Bring two willing allies, or let Matchmaking introduce you to a Fireteam of Guardians.
  
• New Subclasses: The new fighting style for each Class will be at the ready. Choose from the Dawnblade Warlock, Arcstrider Hunter, or Sentinel Titan.
  
• The Farm: For one hour, on Sunday, July 23, we’re inviting you to tour the new social space in Destiny 2. Starting at 10AM Pacific, you’re welcome to kick the ball into the net or befriend a chicken. Most vendors and services will be offline. Our goals are to see how many of you it can accommodate at once.

What you should not expect:

• Clan Support: It’s true that Clans will be supported in Destiny 2, but those features are not a part of this test.
  
• Character Progression: You’ll receive rewards for defeating your enemies – be they Cabal, Vex, or other Guardians – but the Beta does not represent how your characters will evolve in Destiny 2.
  
• Character Continuity: Destiny 2 is a fresh start. Nothing we do in the Beta will carry over to the final version of the game on September 6. Of course, for every rule, there is an exception…
  
  Also, you get a fancy emblem in D2 for participating in the D2 Beta
