The new Close Scrutiny map event has gone live alongside Flashpoint update. This event doesn't significantly alter the environment itself; instead, it focuses on introducing a special type of ARC device known as Assessor.
You must locate and activate these devices to reap the event's most valuable rewards; however, doing so will inevitably attract a swarm of enemies, as well as rival PvP players, all vying for the same loot.
So, how exactly does this event work? How can you survive until the end and make off with the prizes? We're here to show you how.

Close Scrutiny mechanics
Periodically, this event will trigger across any of the outdoor maps, meaning Stella Montis is excluded. While the event is active, the drop rate for standard loot across the map is reduced; however, the quality and quantity of loot obtained by eliminating ARC enemies are significantly boosted.
Therefore, your primary objective is to locate as many Assessors as possible, which spawn exclusively during Close Scrutiny events, activate them to claim their internal rewards, and eliminate any additional bots that are drawn to the area by Assessors' activation.
Common rewards found within Assessors include ARC Raiders blueprints, ARC materials, and supplies that can be submitted toward the new High-Gain Antenna project.
Compared to other methods, the likelihood of finding blueprints for the newly introduced weapons, Canto and Dolabra, is significantly higher within Assessors, making them an opportunity you won't want to miss!
However, given the inherent dangers of the map event itself and the heavy combat focus of Close Scrutiny, we strongly recommend participating only if you are sufficiently well-geared. And ideally, if you are playing as part of a squad with friends.
It is also worth noting that while Close Scrutiny is active, all locked doors across the map become unlocked. This means you can freely loot locked rooms and areas, even if you don't possess the corresponding keys!
How to utilize Assessors?
A few minutes after Close Scrutiny begins, Assessors will begin to spawn periodically across the entire map. Unlike smaller bots or those adept at camouflage, Assessors are massive, tripod-mounted devices that descend from the sky emitting a distinct red glow, making them quite easy to spot.
Once you've located an Assessor, rest assured that it will not attack you directly. Simply wait for it to deploy its internal platform, then climb up one of its legs (the structural supports) to access its loot pool and claim your rewards.
However, once an Assessor is opened, it immediately triggers a piercing alarm that draws in other combat-class ARCs from the vicinity. And naturally, alerts any other Raiders currently venturing through the area.
If you are playing solo, or if your squad lacks sufficient overall combat strength, we recommend using proximity chat to establish friendly communication with nearby strangers; cooperate to defeat ARC enemies, and then split the loot evenly.
As long as you remain in the area, Assessor will continue to attract incoming enemies. Therefore, the optimal strategy is to designate one or two team members to handle looting the device while the others focus on eliminating the bots; once all supplies have been secured, extract immediately.
If you still prefer a solo playstyle, or wish to minimize risk as much as possible, consider equipping a Photoelectric Cloak from the outset to approach the device undetected. Once the alarm sounds, deploy smoke grenades and set up Surge Coils.
Enemy types to watch out for
Theoretically, once the alarm sounds, any type of enemy present in the vicinity of Assessors will be drawn toward the source. However, particular attention should be paid to two specific threats: the newly introduced Vaporizer and Shredder, which is now making its debut across all maps.
Vaporizer
Introduced as part of Flashpoint update, Vaporizer is a large, airborne ARC unit boasting formidable offensive and defensive capabilities. It specializes in attacks utilizing a line-of-sight laser beam, which ignites intense fires at any location it makes contact with.
The moment you land a hit on a Vaporizer, regardless of the method used, it will passively activate a shield capable of blocking all projectile damage. Note, however, that this shield operates on a cooldown timer.
Consequently, the best strategy for dealing with a Vaporizer is to first move quickly to find cover, then avoiding its laser sweep attacks. Next, use any projectile weapon to land a hit from a safe distance, thereby triggering Vaporizer's shield.

Once the shield deactivates and enters its cooldown phase, aim your high-damage weapon at the small rectangular panel located on the underside of Vaporizer; firing at this specific point will force its core components to become exposed. Continue firing at the exposed core to bring the enemy down.
Besides the rewards found within the Assessor itself, Vaporizer drops other loot upon destruction; furthermore, the quantity of ARC materials dropped increases during Close Scrutiny event:
- ARC Powercell
- ARC Alloy
- Electrical Components
- Advanced ARC Powercell
- ARC Flex Rubber
- Energy Clip
- Heavy Gun Parts
- Vaporizer Regulator
Shredder
This enemy previously spawned exclusively in Stella Montis, but it can now be encountered across all maps. Although it is not a true airborne ARC unit, it hovers slightly, granting it superior mobility compared to standard ground-based enemies.
Shredder's primary attack involves firing multiple shrapnel projectiles in all directions, followed by periodic charge-ups to unleash a larger, explosive blast.
Currently, the most effective strategy for defeating a Shredder is to bombard it with grenades while simultaneously using firearms to target its thrusters or propulsion units (the blue jet vents or propellers).
Potential loot drops include:
- Shotgun Ammo
- ARC Powercell
- ARC Alloy
- Mechanical Components
- Simple Gun Parts
- ARC Synthetic Resin
- ARC Thermo Lining
- Shredder Gyro

PvP strategies
The appearance of Assessors inevitably attracts other players roaming the vicinity, either to compete with you for the loot or simply to lie in wait and ambush you once you have finished clearing the area.
Therefore, in addition to bringing reliable gear, your squad should designate one member to serve as a dedicated lookout during the latter stages of the encounter.
This individual should focus on preventing rats from approaching and ensuring that a sufficient number of Surge Coils are deployed.
That concludes our guide to ARC Raiders Close Scrutiny event. If you and your friends are confident in your abilities, gear up and embark on your adventure now!
