Operation Broken Mirror

Operation Broken Mirror is a multi-step operation in Endgame that players can complete across multiple matches. It tracks progress persistently, meaning each completed step carries over between sessions. Completing all 10 steps earns calling cards and serves as part of the Endgame progression structure introduced alongside Guild Strikes.

Rewards overview

Operation Broken Mirror rewards calling cards at various completion milestones. A master calling card is awarded for completing all 10 steps.

Additional calling cards tied to the Broken Mirror operation include Hot Streak, Juiced, Overencumbered, Rough Road, Thermonuclear, and Underdog, each unlocked by specific in-match actions related to the operation steps.

Note

Progress in Operation Broken Mirror persists across matches. You do not need to complete all 10 steps in a single session. Each completed step is permanently banked.

Full walkthrough

1. Walk Tall - The opening step of the operation. Establish your presence in Avalon by completing the initial objective. This step serves as an introduction to the operation’s structure and requires a basic activity completion.

   

2. On the Trail - Track and locate a Guild target. Progress requires locating a specific marked enemy or objective within Avalon. Completing this step rewards loot that can assist with subsequent steps.

   

3. Step 3 - The third objective advances into Guild-controlled areas and requires eliminating a specific wave of enemies or completing a designated activity. Detailed notes for this step are pending community documentation.

4. Shifters in the Mist - Engage and eliminate Shifter-class enemies (Mimics) in a designated area. Shifters are Special-class enemies that can change shape. Weapons with area-of-effect damage or rapid-fire capabilities are effective.

   

5. System Intrusion - Infiltrate and interact with a Guild computer system or terminal. This step involves a timed interaction while enemies attempt to interrupt the process.

   

6. Power Chain - Destroy or disable a sequence of Guild power infrastructure. Multiple targets must be neutralized in order. This step spans a wider area than earlier steps.

   

7. Fear Hunter - Hunt and eliminate Fear-class enemies (Zombies) in a specific location. Fear enemies in later zones have increased health and can spawn in dense groups.

   

8. Blade and Flame - A combat-focused step requiring melee and incendiary-type eliminations. Community reports note this step has experienced bugs in certain versions. Verify the step registers correctly after completing the required kills.

   

   Caution

   Step 8 (Blade and Flame) has been reported as bugged by multiple community members. If the step does not register after completing the objective, try completing the action in a different zone or rejoining a fresh match. This appears to be an intermittent tracking issue.

9. Infestation - Clear an area heavily populated by Fear and Vermin-class enemies. The step requires eliminating a high number of enemies within the infested zone within a time limit.

   

10. Virus Injection - The final step of Operation Broken Mirror. Complete the Virus Injection objective to finish the operation. This step connects directly to Operation Poison Pill mechanics and involves interacting with Guild systems to deliver a payload.
