Watch Destiny: The Taken King's PlayStation-exclusive strike today (update)

Destiny: The Taken King includes one PlayStation-exclusive strike, Echo Chamber, and Sony will be livestreaming a full playthrough of the three-player cooperative activity this afternoon, the company announced on Twitter.

Echo Chamber takes place on Venus, where the Vex are trying to call back Sekrion, the Nexus Mind — whom Guardians defeated in the original Destiny strike called The Nexus. In order to stop the Vex, Guardians will have to take down a challenging boss known as the Restorative Mind.

Like all of The Taken King's PlayStation-exclusive content, Echo Chamber will be unavailable to Destiny players on Xbox 360 and Xbox One until fall 2016.

Sony's livestream of the Echo Chamber strike will begin at 2 p.m. PT on the PlayStation Twitch channel. The Taken King will be released Sept. 15 on PlayStation 3, PlayStation 4, Xbox 360 and Xbox One. For more, check out our everything-you-need-to-know StoryStream.

Update: Sony will also be unboxing the limited-edition Taken King-themed PS4 bundle during the livestream, the company announced on Twitter.
