History of Eerie Ops

Overview

Eerie Ops is a Triumph in Destiny 2 tied to the Festival of the Lost event. It requires five Ops activities completed while Festival of the Lost modifiers are active. The game data lists no score.

How to complete

1. Start the Festival of the Lost event. The 2025 event ran from October 21 to November 4, so the event is active for roughly two weeks each autumn.
2. Play Ops activities while the event modifiers are on. The counter is 0/5, so five completions are needed.

The event's other triumphs, such as Horrific Taunts and Hocus Focusing, are tied to Haunted Sectors and Eerie Engrams, not to Ops activities.
