The Flashpoint update added the High Gain & Turnout project, and the good news is that it’s much faster than it looks once you understand where each component drops and how to route maps efficiently. This guide breaks down every required item across all phases, which Ark types to target for each material, and the single most time-saving trick: prioritizing the Close Scrutiny map condition and racing laser-beam spawns before other raiders arrive.

High Gain & Turnout Rewards (What You’re Working Toward)

Completing the project grants a bundle of gear and attachments, including a Torrene, Bobcat, Snap Hook, Padded Stock, Extended Barrel, Raider Coins, and additional weapon attachments. The exact value depends on your current loadout, but the attachment spread is especially useful if you’re still stabilizing recoil control and effective range on your main weapons.

How the Project Works (Phases and Turn-Ins)

The project is split into multiple pages/phases with specific turn-ins. Most requirements are scavenged from Arks you kill and loot, while two key items are tied to specific spawns that are easiest to force in Close Scrutiny.

• Most materials: drop as scavengable parts from common Ark enemy families.
• Assessor Matrix: only appears in Close Scrutiny via red-laser spawns.
• Surveyor Vaults: tied to Surveyor kills, best tracked by white-laser spawns.

Phase 1 Turn-Ins: Core Ark Materials

Phase 1 is primarily about building a “kill-and-scavenge loop” on Ark-heavy routes. If you’re missing multiple items, don’t tunnel on a single enemy type; instead, target zones where several listed Ark variants overlap so you progress multiple turn-ins at once.

Arc Alloy

How to get it: commonly found on many Ark enemies you take down. If your stash is cluttered, you can also recycle items into Arc Alloy to close small gaps.

Best approach: treat Arc Alloy as a passive pickup while you farm the more specific materials below.

Arc Flex Rubber

Drops from: Baron Husks, Bastions, Bombarders, Leapers, Matriarchs, Queens, Sentinels, Ticks.

Tip: if your route has consistent Leaper/Tick pressure, it’s often an efficient rubber farm because those encounters chain quickly and keep your scavenging momentum high.

Drops from: Baron Husks, Bastions, Bombarders, Hornets, Leapers, Matriarchs, Queens, Surveyors.

Tip: Surveyors contribute to Phase 3 as well, so any area with Surveyor spawns is effectively “double dipping” your time.

Advanced Arc Power Cells (15)

Drops from: Comets, Couriers, Bastions, Bombarders, Leapers, Queens, Rocketeers, Rocketeer Husks, Sentinels, Surveyors, Matriarchs.

Threat note: Rocketeers and their Husk variants can punish greedy looting. Clear angles first, then loot cores/armor when you’re not exposed.

Phase 2 Turn-Ins: Cooling, Lining, and the First Assessor Matrices

Phase 2 introduces the project’s first “gated” component: the Assessor Matrix. You can still make strong progress on coolant and lining while you hunt matrices, but your completion speed will hinge on how well you run Close Scrutiny spawns.

Arc Coolant (15)

Drops from: Baron Husks, Comets, Fireballs, Pops, Queens, Sentinels, Arc Surveyors.

Tip: because several of these are also common in Ark-dense conditions, you’ll often finish coolant naturally while pursuing matrices.

Arc Thermo Lining (15)

Drops from: Baron Husks, Comets, Fireballs, Pops, Queens, Sentinels, Snitches, Ticks, Turrets, Wasps.

Tip: Turrets and Wasps can slow you down if you fight them head-on. Use cover to break line-of-sight, then re-peek to finish quickly before scavenging.

Assessor Matrix (6)

Where it comes from: only from the Close Scrutiny map condition.

How to find it: when you load in, look into the sky for bright red laser beams. Those beams mark where Assessors spawn.

How to loot it: the Assessor is heavily guarded by Arks. Once you win the fight, you’ll need to reach the top layer, breach, and search to find the matrix inside, often alongside other valuable parts.

Loadout advice: bring extra healing, strong shields (a big shield if possible), and a weapon setup that deletes Ark targets efficiently. You’re likely to get surrounded quickly if you hesitate at the container.

Phase 3 is where routing matters most. You need a sizable chunk of matrices and a separate set of items that are easiest to gather by forcing Surveyor activity.

Surveyor Vaults (10)

How to get them: kill Surveyors and scavenge their armor/core. Occasionally you may see multiple vaults from one Surveyor, but most kills yield one.

How to locate Surveyors fast: on spawn, Surveyors often broadcast a white laser beam into the sky. Use it as a navigation beacon to decide your first rotation.

Best condition: Surveyors spawn more frequently in Close Scrutiny, which is why it’s the best “one-stop” mode for finishing the entire project.

Arc Synthetic Resin (20)

Drops from: Baron Husks, Forerator Husks, Matriarch, Queen, Sentinels, Shredders, Snitches, Spotters, Turrets, Wasps.

Tip: resin is a classic “farm while moving” material. Prioritize targets you can kill without stopping your rotation for long firefights, then only commit to Turrets/Wasps when you have safe angles.

Assessor Matrix (18)

Reminder: this is the same Close Scrutiny red-laser mechanic as Phase 2, just a larger quantity. If you optimize your Assessor runs early, Phase 3 becomes mostly cleanup.

The Fastest Completion Method: Close Scrutiny + Laser-Beam Racing

If you want to finish High Gain & Turnout as fast as possible, structure your sessions around Close Scrutiny and treat laser beams as your entire routing plan.

• Queue Close Scrutiny repeatedly. It concentrates the exact Ark spawns you need for rubber, steel, power cells, coolant, lining, resin, and Surveyor Vaults.
• At match start, scan the sky immediately. Red lasers mean Assessors; white lasers point you toward Surveyors.
• Be first to the red laser. Assessors are guarded, but clearing them yields a dense pile of relevant parts, and can accelerate multiple phases at once.
• Loot discipline wins time. Clear the immediate swarm, then breach/search quickly. Hanging around invites third-party pressure and extra Ark waves.

Survival and Efficiency Tips for Assessor and Surveyor Hunts

Assessor sites can collapse into close-range chaos. Stack enough healing and shields to survive a sudden push while you’re locked into breaching/searching. If you can’t sustain, you’ll lose time re-kitting and re-queuing.

Use a weapon that deletes Arks quickly

Time-to-kill matters more than ammo efficiency at these objectives. The faster you clear the initial guard pack, the safer the breach becomes and the less likely you are to get pinned while looting.

Prioritize overlapping drop tables

When you’re choosing which fights to take, favor Ark types that appear on multiple lists (for example, Queens, Sentinels, Baron Husks, and Surveyors). This reduces “dead runs” where you only progress one requirement.

Know when to disengage

If you arrive late to a red-laser site and hear heavy fighting, it’s often faster to rotate to the next beam than to force a risky third-party engagement. The goal is consistent completions, not heroic holds.

Quick Checklist: What to Farm First

If you want a simple priority order that matches the project bottlenecks:

• Assessor Matrix (Close Scrutiny red lasers) whenever you see it
• Surveyor Vaults (follow white lasers, kill-and-scavenge)
• Advanced Arc Power Cells (broad drop list, easy to finish while doing the above)
• Arc Coolant and Arc Thermo Lining (usually finish naturally in Ark-dense runs)
• Arc Synthetic Resin (cleanup via common Ark families)
• Arc Alloy (passive + recycling to top off)

Frequently Asked Questions

No. The Assessor Matrix is tied to the Close Scrutiny condition, and you should use red laser beams to locate the spawn quickly.

What’s the easiest way to find Surveyors for Surveyor Vaults?

Look for the white laser beam into the sky at the start of a run, then rotate directly to that position and scavenge the Surveyor’s armor/core after the kill.

Why do I keep getting swarmed at the Assessor site?

Assessors are heavily guarded and can pull additional Ark pressure while you loot. Bring more healing and shields than usual and clear the immediate area before breaching.

Which items can I realistically finish “passively” while farming matrices?

Arc Coolant, Arc Thermo Lining, and many Advanced Arc Power Cells tend to complete naturally because their drop tables overlap with common Close Scrutiny Ark spawns.

I’m short on Arc Alloy at the end. What should I do?

Farm a few Ark-dense runs for quick scavenges, then recycle spare items to top off the remaining Arc Alloy without changing your route.
