Destiny: Age of Triumph is an update intended to bid farewell to Bungie's game (but don't worry, Destiny 2 is definitely coming), and this update will arrive today, which, as per usual, means maintenance for the servers.
For us here in Europe, the download is occurring at 18:00 BST/19:00 CEST, as explained by Bungie, so if you're playing at that time, you'll need to download the update to continue.
Will you still play Destiny up until the release of the sequel?
