The latest Destiny 2 event, Iron Banner, is live now in the Crucible. The event returns from the original Destiny, offering exclusive armor and gear if you earn enough Tokens.

Another event, the Leviathan Prestige Raid, was due to go live today, but that has now been delayed until Wednesday, October 18. Bungie said: "An exploit has been discovered in the Leviathan Raid that causes the encounters to be stripped of their intended challenge. To allow time to fix this issue, we are delaying the start of the Prestige Raid until next week. It's important to us that the team who earns World First status doesn't have their legacy tarnished by doubt, skepticism, or uncertainty." However, the release of Destiny 2's new map, Distant Shore, went ahead as planned and it's live now.
