ARC Raiders Guide: Where to Find All Resources and Items for Quests, Plyushkin, the Workshop, and the Expedition

If you’re as fed up as I am, we’ll help you get to the heart of the matter. This guide lists all 62 unique items needed for quests, upgrades to Plyushkin the Rooster and the Workshop, and the “Expedition” project. Altogether, that amounts to a staggering 1,195 pieces of materials you’ll need to haul to Speranza. I hope my math skills are up to par. However, while I was crunching the numbers, a few interesting points came up.

First, you’ll have to search almost every ARC vehicle in the game except the Queen. As you might expect, you’ll need more parts from regular ARC vehicles than from more dangerous enemies, but you’ll need 6 Bastion and Bomber Drivers, 6 Observer Safes, and 8 Jumper Pulse Modules. It’s safe to say that Jumpers are the most annoying mobs, and Observer drones are so skittish that they’re difficult to track down, much less destroy.

Therefore, if you manage to obtain these items before the corresponding upgrade quest appears, keep them in storage and don’t sell them! Otherwise, you’ll later complain about not being able to obtain the items you needed or selling them for next to nothing.

I also noticed that you need a small collection of broken items. These are versions of things that at first glance seem completely useless: burnt-out motherboards , rusted medical kits, and a damaged heat sink.

I used to completely ignore them, but it turns out they’re required for important upgrades to the Toolbox and Weapons Station. Now I’ll have to keep in mind that these things need to be picked up. They’re among those materials that are incredibly difficult to find just when you need them.

Aside from these specific resources, the rest is what you’d expect in a post-apocalyptic world : medicine, metal, fabric, and electronics. Well, that is, unless you consider Plyushkin’s demands for items like fruit, a dog collar, a cat bed, and pillows .

And yes, I have some disappointing news: with a maximum storage capacity of just 280 units, you’ll never be able to keep all your items in stock at once. And you don’t need to—just spend them whenever you see an opportunity to upgrade.
