ARC Circuitry doesn't matter until suddenly it's the only thing standing between you and Refiner Level 3. Then it's the only thing you care about.

Here's the fast version: farm intact ARC Probes, ideally during the Prospecting Probes event, on Spaceport. Everything else is a backup plan.

↖ Why You Need ARC Circuitry

This isn't a side material. It gates your core progression.

The bottleneck: you need Circuitry to unlock Refiner Level 3, but Refiner Level 3 is how you craft Circuitry later. No shortcuts around the early grind.

↖ Best Source: Intact ARC Probes

Broken probes drop Circuitry too — occasionally. Intact probes drop it consistently, sometimes multiple pieces if you crack every panel.

Rule of thumb: don't hunt a probe. Hunt an intact one.

1. Confirm it just landed — not scorched, not smoking.

2. Clear the area first (loot pulls players like a magnet).

3. Pop every side panel — one panel ≠ full loot.

4. Grab the Circuitry, then decide: push your luck or bail.

↖ How to Actually Find Probes

↖ Follow the Sound

Probes emit a high-pitched beeping that gets louder as you close in. Broken ones sound glitchier, more damaged. If the beep fades — you're going the wrong way. Turn around.

Sound tracking beats sightlines every time. Probes hide behind buildings, terrain, and firefights constantly.

↖ Know the Timing

In tested runs, probes started dropping around the ~25-min remaining mark — roughly 5 minutes into the raid. Not gospel, but a solid window to start scanning.

↖ Take High Ground

Roof, ridge, tower — anything above ground level. From up top you can spot:

• Falling probes and smoke trails
• Open landing zones before anyone else gets there
• Enemy or player traffic converging on the same spot

Ten seconds of scanning from a rooftop beats two minutes of blind sprinting.

↖ Farm During Prospecting Probes

This event straight-up increases probe spawn density across the map. More probes = less walking, more looting, faster runs.

Loop that works:

1. Spawn → scan sky/open ground immediately

2. Push to high ground

3. Track by sound

4. Hit intact probes first, broken ones only if free

5. Extract once you've banked enough — don't get greedy

↖ Best Map: Spaceport → Rocket Assembly

Open desert, long sightlines, minimal clutter blocking your view of falling probes. Rocket Assembly specifically gives you a massive landmark to navigate around while scanning.

Solo? Check your six before sprinting across open sand. Valuable loot attracts company.

↖ Intact vs. Broken: Know the Difference

If you're already extracting and pass a broken probe, glance at it. Don't detour hard for one — that's not the play.

↖ Crafting ARC Circuitry (Refiner Level 3+)

Once your Refiner hits Level 3, you can convert ~6 ARC Alloy → 1 ARC Circuitry. Values may shift with patches, but the ratio's roughly there.

Translation: early game, you farm manually. Post-Refiner-3, you top up with Alloy conversion instead of raiding probes every time. Both paths matter at different stages — don't skip probe farming trying to unlock your way out of it.

↖ Mistakes That Kill Your Runs

• Muting your audio. You're throwing away your best tracking tool.
• One panel and done. Multiple panels = multiple rolls. Check them all.
• Overstaying a good haul. Got 3+ Circuitry? Extract. Don't chase a 4th and lose everything.
• Relying on broken probes. They're a bonus, not a strategy.
• Recycling too early. You need Circuitry more than Alloy until Refiner Level 3 is done.

↖ Quick Priority Checklist

↖ FAQ

↖ What's the fastest way to farm ARC Circuitry?

Hit intact ARC Probes during the Prospecting Probes event. Nothing else comes close in reliability.

↖ Which map is best for farming?

Spaceport, especially around Rocket Assembly — open sightlines make probes easy to spot and track.

↖ Do broken probes drop Circuitry?

Yes, but at a noticeably lower rate. Treat them as a bonus, not your main plan.

↖ When do probes usually spawn?

Around the 25-minute remaining mark in most tested runs — roughly 5 minutes after raid start. Timing isn't fixed, but it's a strong window to start scanning.

↖ Can I craft ARC Circuitry instead of farming it?

Only after Refiner Level 3, using roughly 6 ARC Alloy per Circuitry. Before that, you're farming manually — no way around it.

↖ Bottom Line

Farm intact probes. Do it during Prospecting Probes. Do it on Spaceport. Track by sound, scan from high ground, crack every panel, extract with your loot instead of pushing for one more probe.

Save your first batch for Refiner Level 3. Once that's unlocked, crafting picks up the slack. Until then — probes are the entire game.
