Destiny 2's Prometheus Lens, a trace rifle weapon added in the newly released Curse of Osiris expansion, is broken. Not broken in the way that fans sometimes refer to a weapon in a game that they feel is overpowered; Prometheus Lens is devastatingly effective in Crucible, and Bungie said that's because of a bug. A fix won't arrive until next week, and players speculated that its power could cause the cancellation of this weekend's Trials of the Nine event, similar to what happened when a map exploit was discovered in October. Instead, Trials is going ahead, and Bungie is leaning into the entire situation.
