ARC Raiders Just Added Permanent Weather Monitor System Project | Defeating New Enemy Types Is Key to Obtaining the Rewards!
Category: ARC Raiders Posted: Feb 25, 2026 Views: 631
Most of the time, ARC Raiders includes a complete project with major updates. These projects involve various specific tasks, requiring you to defeat enemies or collect items to unlock rewards.
The last such project was Flickering Flames event during Cold Snap, which required collecting the limited-time material Candleberries. Yesterday's Shrouded Sky update brings Weather Monitor System project.
So, what materials do you need to collect for this new project, and what rewards do you get upon completion? We'll provide a detailed overview.

Weather Monitor System Project Overview
Unlike Flickering Flames, this project is a permanent feature, meaning you can continue playing even if you don't have time to play for a month for any reason.
From a narrative perspective, this project was established because of the dangerous winds caused by the new map condition, Hurricane. Building a weather forecasting system to provide early warnings is essential.
While the map conditions aren't necessarily triggered by this forecast system, you can unlock massive rewards by collecting specific materials, and you might even obtain extra ARC Raiders blueprints during the collection process - why not?
The entire project is divided into five stages. You only receive the rewards after collecting all the items in the current stage. Some materials can be found directly through scavenging. Others may require defeating ARC enemies to obtain them as drops.
Stage 1: Atmospheric Pressure
- 25x Plastic Parts
- 15x Metal Parts
- 5x Arc Alloy
- 3x Oil
We've listed all the materials needed for each stage to help you start farming immediately after understanding how to obtain them. But if you're unsure how to obtain certain items, don't worry, we'll explain each one.
Unsurprisingly, as the initial stage, the items required for Stage 1 are easy to obtain. You can find plenty of Plastic Parts and Metal Parts almost anytime you go out and complete raids, and defeating any PvE enemy will yield Arc Alloy.
The only slightly tricky item is Oil, but it's easy to find if you're familiar with its main spawn locations, such as the mechanical zones on various maps. Alternatively, you can obtain it by recycling other items.
After completing the collection, Stage 1 rewards the following:
- 5x Durable Cloth
- 5x Great Mullein
- 5x Antiseptic
- 3x Vita Shots
Stage 2: Sunlight
- 1x Snitch Scanner
- 3x Wires
- 3x Sensors
- 1x Comet Igniter
The difficulty of this stage lies in defeating the new ARC enemy, Comet, introduced in this update to obtain Comet Igniter it drops.
Comets can be found in most areas. They are large metal spheres with a light on the front and a light strip above them. They constantly move and patrol, and their light turns from yellow to red when they spot a target.
The key to defeating this enemy is to run away immediately after being spotted to avoid the explosion damage they create - your attacks may accelerate their self-destruction. After the explosion, you can collect the loot.
As for other materials, Snitch Scanners can be obtained by killing Snitches. Wires can be found directly in electrical and technological areas, or you can obtain them by dismantling electrical appliances.
Sensors have a wider range of sources. Scavenging in security and technological areas, recycling other items, and killing Snitches or Surveyors can all drop Sensors.
- 10x Processor
- 5x Advanced Electrical Components
- Zipline
- Raider Hatch
Stage 3: Precipitation
- 5x Arc Powercell
- 12x Canister
- 3x Steel Spring
- 1x Fine Wristwatch
Arc Powercells drop from most common PvE enemies. Canisters and Steel Springs can be found in commercial and industrial areas respectively, and are also sold by vendor Celeste.
Fine Wristwatches can be found in commercial and residential areas, but we recommend farming them by looting bird nests on the map after Bird City map condition appears.
- 3x Medium Gun Parts
- 2x Complex Gun Parts
- 3x Advanced Mechanical Components
- 1x Renegade III
Section 4: Humidity
- 10x Duct Tape
- 3x Rusted Bolts
- 1x Water Pump
- 3x Wasp Driver
Duct Tapes can be found directly in Residential and Commercial areas, or you can obtain them by recycling mods or trading with Celeste if you have enough weapon mods or coins.
Additionally, you can quickly find some Rusted Bolts and Water Pumps by carefully searching mechanical and industrial areas. Wasp Drivers will drop after you kill Wasps.
- 10x Explosive Compounds
- 3x Showerstoppers
- 3x Trailblazers
- 1x Extended Barrel attachment
Section 5: Temperature
- 3x Camera Lens
- 1x Damaged Heatsink
- 1x Firefly Burner
- 3x Voltage Converter
Firefly is the other new enemy added in Shrouded Sky update, Firefly Burner is its drop. The key to defeating it is to aim for the two rear rotor fans or the armor on the front fan.
The difficulty of this encounter lies in Firefly's ability to breathe fire, which is difficult to dodge. Therefore, it's best to eliminate it quickly or find cover before attacking. Having grenades will make the fight much easier.
Camera lenses and Damaged Heatsinks are commonly found in security areas and technological areas, respectively. As for Voltage Converter, it can be found in electrical areas or obtained by recycling specific items, such as Ion Sputters or Signal Amplifiers.
- 10x Explosive Compounds
- 3x Showerstoppers
- 3x Trailblazers
- 1x Extended Barrel attachment
Summary
Collecting these materials shouldn't be difficult for someone familiar with ARC Raiders gameplay; it just requires a significant time investment. You can choose to complete each stage individually or submit them all at once after acquiring all the materials.
Regarding the rewards, while there aren't many finished weapons, the large amount of high-level crafting materials will help you craft the gear you want more easily - provided you have the corresponding blueprints.
That's all the information you need to complete Weather Monitor System project. Although it's not time-limited, we still recommend completing it as early as possible to enjoy the benefits of the rewards sooner!
