I didn't expect the Shrouded Sky patch to mess with my raid routine as much as it did. One run it's bright and readable, the next you're stuck squinting through wind and rain, trying not to get dragged into a bad fight. That's why the Weather Monitoring System project matters, and why it's worth checking what you've already got in your stash from ARC Raiders Items and everyday scavenging before you even think about "grinding" anything.

Atmospheric Pressure Is Your Easy On-Ramp

The first stage, Atmospheric Pressure, looks like it's going to be some huge checklist, but it's honestly a soft start. You're handing in 25 Plastic Parts, 15 Metal Parts, 5 ARC Alloy, and 3 Oil. Nothing exotic. No "go farm a nightmare bot for a 1% drop" nonsense. If you're already hitting industrial spots, loading docks, or those commercial backrooms where you always find junk anyway, you'll probably tick this off without trying.

Where These Materials Usually Come From

Most people overthink the sourcing. Plastic Parts and Metal Parts show up everywhere once you start opening toolboxes, shelves, and storage piles with any discipline. ARC Alloy is the only one that might slow you down a bit, but it's still not some mythical item—you'll see it often enough if you're looting consistently and not sprinting past everything. Oil is the funny one: you only need three, so it's less "hunt" and more "don't sell it the moment you extract." A decent habit is to set a tiny stash rule for yourself: keep one stack of each project material, then stop worrying about it.

Turn-In, Instant Payoff, And Why It Helps

Once you've got the bundle, just drop it into the project screen under your Raiders tab. It's immediate. No timer, no waiting, no awkward "come back later." The rewards are the kind you actually burn through in Shrouded Sky: Durable Cloth, Great Mullein, Antiseptic, and Vita Shots. Those last two are huge when weather chaos forces you into messy skirmishes or longer rotations. People talk about weapons and armor all day, but healing and craft basics are what keep a run from turning into a panic extraction.

Setting Yourself Up For The Next Stages

The nice thing is there's no pressure to rush the whole Weather Monitoring System in one weekend. Later stages like Sunlight, Precipitation, Humidity, and Temperature ask more from you, and you'll feel it if your inventory habits are sloppy. So play normal, stash the common parts, and turn them in when it's convenient. If you're trying to smooth out progression for your squad, some players also top up missing materials or gear through trusted marketplaces like U4GM, which can save time when you're short on essentials and just want to get back into raids without derailing your night.
