The ESR Analyzer in ARC Raiders is not a loot item — it is a Quest Item required to complete the mission A Reveal in Ruins, handed out by NPC Lance. Unlike the Spectrum Analyzer in ARC Raiders, which has economic value as a recyclable item, the ESR Analyzer serves no purpose outside of quest progression. Most Raiders who search for an arc raiders esr analyzer guide do so because they are stuck — and that is exactly what this page solves.
ESR Analyzer ARC Raiders: What Makes It Different
If you came here looking for an ESR Analyzer value calculator in ARC Raiders, you will be surprised to learn there is nothing to calculate. The ESR Analyzer is:
- Non-sellable: No trader in ARC Raiders will buy the ESR Analyzer. It does not appear in any vendor menu.
- Non-recyclable: The ESR Analyzer cannot be broken down at the Raider Den for materials. Recycling options are completely disabled for this item.
- Non-craftable: The ESR Analyzer is not a crafting ingredient. It has zero manufacturing value in ARC Raiders.
- Ultra-low weight: At just 0.25 kg, the ESR Analyzer barely registers in your inventory — but its quest value is enormous.
Where to Find the ESR Analyzer in ARC Raiders
The ESR Analyzer only appears inside Buried City — the underground dungeon area of ARC Raiders. It is not found in Stella Montis, Rust Yards, or any surface map. Use this exact targeting method:
- Look for Pharmacy buildings marked with a green cross icon on the in-game map.
- Piazza Arbusto (Southeast Buried City): A primary Pharmacy spawn point. All interior tables are searchable.
- Plaza Rosa (Central Buried City): A secondary Pharmacy near the main plaza's subway entrance. The underground tunnels here have extremely high ARC foot traffic and frequent drone patrols — come prepared with EMP grenades.
Supply crates, weapon lockers, and standard loot containers in Buried City will never contain the ESR Analyzer. Only the green-cross Pharmacy buildings trigger the spawn.
The Safe Pocket Rule: Your Only Protection Against Permanent Loss
This is the most important warning for any Raider seeking the ESR Analyzer in ARC Raiders. Unlike standard loot, the ESR Analyzer is not protected by the insurance system. The only way to prevent permanent loss is equipping a Safe Pocket augment before entering Buried City.
If you die without a Safe Pocket: the ESR Analyzer disappears from your inventory permanently. There is no way to recover it. You will have to run Buried City again and re-farm it from the Pharmacy. Many Raiders have learned this lesson the hard way.
Equip your Safe Pocket augment, follow the checklist above, and extract immediately after picking up the ESR Analyzer. No detours. No extractions. No second chances without re-running the dungeon.
Post-Extraction: How to Turn In the ESR Analyzer
Successfully extracting from the underground tunnels of Buried City with the ESR Analyzer is only half the battle. Once you return to the surface, you must manually hand over the item to complete the quest.
- Return to Lance: Head back to your faction's main hub/base. Locate NPC Lance (the quest giver for A Reveal in Ruins).
- Interact and Deliver: Open the dialogue menu with Lance. The option to turn in the ESR Analyzer will now be unlocked.
- Claim Your Reward: Handing over the item completes the quest, rewarding you with substantial faction reputation and unlocking the next tier of vendor supplies.
Final Reminder: Do not attempt to stash the item in your Raider Den and forget about it. Keep it in your inventory when speaking to Lance to trigger the completion dialogue.
