The first time I queued into a topside run after Shrouded Sky, I realised the sky isn't just scenery anymore. Weather has teeth, and it can shove you off your usual routes fast. That's why the Weather Monitoring System matters, and the opening step, Atmospheric Pressure, is basically the game's way of saying "learn the loop first." If you've been stashing ARC Raiders Items and components without thinking too hard about it, you're already halfway there, because this phase leans on everyday scavenging rather than hero plays against high-tier ARC threats.



What You Actually Need
The checklist is simple and, honestly, kind of refreshing: 25 Plastic Parts, 15 Metal Parts, 5 ARC Alloy, and 3 Oil. None of that screams "endgame grind." You'll pick most of it up by doing normal laps through industrial yards, loading bays, storefront back rooms, and all the little side rooms people usually rush past. Plastic and metal come in steady if you're looting containers instead of only chasing gunfights. Oil's the one that can trip people up, but it's still common enough that you don't need to plan your whole run around it. Once the stacks are there, you just open the Raiders tab, find the project UI, and donate—no timers, no weird hand-in animation, it just completes.



Why This Phase Feels So "Free"
Atmospheric Pressure is forgiving on purpose. It nudges you into the new rhythm: loot, extract, sort your stash, then invest in long-term projects. And because the station doesn't expire, you can play it casual. A lot of squads do the same thing: they'll keep a "project shelf" in the stash, dump spare parts there after each extraction, and only hand them in when it's convenient. That habit pays off later when the weather starts forcing tougher choices—do you push through a storm for one more crate, or cut losses and get out?



Rewards That Actually Matter Early
Finishing the phase kicks back a small care package: Durable Cloth, Great Mullein, Antiseptic, and Vita Shots. It doesn't look flashy, but it's the kind of kit you end up wishing you had when a run goes sideways. Vita Shots let you stabilise quickly, antiseptic helps keep your healing and crafting options open, and the cloth plus plants are great for keeping your medical pipeline moving. The best part is how this ties into the bigger weather chain—Sunlight, Precipitation, Humidity, Temperature—where you'll need that stash discipline and those quick recovery tools to stay consistent.



Keeping It Smooth for the Next Stages
If you treat Atmospheric Pressure like a warm-up, you'll hit the later steps with less friction. Don't overthink it: loot like normal, tag what you're short on, and keep rolling until the piles build up. If you're the type who doesn't have time to grind components every night, it can also help to top up gaps through trading services like U4GM, so you can spend your sessions actually raiding instead of running the same shelves for one missing stack.Welcome to U4GM, where ARC Raiders feels smoother from your very first raid.
