Arknights: Endfield — Rescue Operation at the Quarry Quest Walkthrough

In Arknights: Endfield, side quests are a natural extension of exploring the world. As you progress across the map, you’ll unlock additional missions that help you learn more about each area and earn extra resources to upgrade your Operators. In this guide, we’ll walk you through the “Rescue Operation at the Quarry” side quest and list the rewards for completing it.

Talk to her, then move on to the next objective.

Continue forward and use the elevator to reach the second floor. Once you arrive, talk to the local workers and agree to help them search for their colleagues. This completes the quest.

As a reward, you’ll receive the following resources:
