ARC Raiders Stash Prep Guide With U4N for Better PvE Farming

The upcoming ARC Raiders PvE Matchmaking Toggle Beta is set to run from October 13 through October 20, 2026. It offers a noticeably different way to approach raids because players will not be able to damage one another during the test. However, the safer environment comes with reduced loot value and restrictions on several high-tension locations. That means the best preparation is less about carrying expensive gear and more about creating a stash that supports fast, repeatable farming.

If you have been collecting ARC Raiders BluePrints, weapons, attachments, ammunition, and crafting resources, now is a good time to sort everything out. The PvE test rewards consistency, so having free inventory space and a small collection of reliable equipment can make each run much smoother. Instead of preparing for every possible PvP situation, you can build around fighting ARC enemies and bringing useful resources home.

Start With a Stash Cleanup

I would begin by trying to create around 10 to 15 free stash slots. That gives you enough room to handle the steady flow of materials coming back from repeated farming runs without immediately hitting the inventory limit.

Look for obvious clutter first. Duplicate blueprints, novelty items, and partial ammunition stacks are all worth reviewing. If you have several copies of something that you have never used, keeping every copy is probably not helping your preparation.

Loose attachments are another easy way to waste space. If an attachment is useful, mount it directly onto a weapon you intend to keep. This is much cleaner than having individual attachments spread across multiple inventory slots.

Augments and shields can also be reduced. Keeping fewer than five stacks of each is a practical target. Anything beyond what you regularly use can be crafted or prepared when you actually need it.

Consider More Inventory Capacity

After cleaning the stash, you may still find yourself running out of room. In that case, inventory expansion is worth considering. Players can use accumulated Coins to add 24 slots at a time, with the stash eventually reaching a maximum capacity of 280 slots.

However, more space should not be the first solution. Expanding a cluttered stash simply gives you more room to store things you may never use. Clean out the unnecessary equipment first, then decide whether additional capacity is genuinely useful for your playstyle.

A well-organized smaller stash can often feel better than a huge inventory where important materials are buried between old equipment.

Prioritize Crafting Bottlenecks

The reduced loot value during the PvE test makes material selection more important. You will probably collect a lot of ordinary resources during repeated runs, but not everything deserves permanent stash space.

Common materials that Scrappy can provide easily should be kept under control. If you have excessive amounts, recycle or sell some instead of allowing them to fill multiple slots.

Use your available space for materials that are harder to replace or regularly needed for progression. Batteries, springs, and processors are useful examples. Keeping around 30 of each as a basic reserve can give you enough flexibility for upcoming upgrades without filling the entire stash.

The main idea is simple: make your inventory reflect what you actually need rather than what you happen to find.

Keep Your Weapon Selection Small

The absence of player damage changes weapon preparation considerably. In a normal match, you need to think about both ARC enemies and other Raiders. During this test, that second concern disappears.

For farming, three or four dependable weapons should be enough. Choose guns that you already understand and that perform reliably against ARC enemies.

Before the test starts, check your Research Workstation and consider focusing upgrades on one primary weapon. Taking a dependable weapon toward rank five can make more sense than spreading your resources across several guns that rarely leave the stash.

Test recoil, heat buildup, and ammunition consumption in relatively safe areas. A weapon with slightly lower burst potential can still be a better farming choice if it handles consistently and uses ammunition efficiently.

Rethink Ammunition and Keys

There is also less reason to keep large ammunition reserves. Since another player cannot eliminate you and take your equipment, you can reduce stored ammunition toward zero stacks and craft or purchase what you need immediately before a run.

This frees up valuable stash space for materials. After an extraction, simply replace the ammunition you used before launching again.

Keys deserve a similar review. If you have accumulated a large collection of unused keys, consider using relevant ones during your remaining PvPvE runs rather than allowing them to occupy permanent storage.

Keep the PvE restrictions in mind, though. Night Raids, the Hidden Bunker, Locked Gate, and the Frigate are unavailable in the test queue. Keys associated with those locations may therefore have limited value during the event.

Build a Repeatable Farming Loop

The most useful mindset for this test is to stop judging every raid by the value of a single item. Loot values are reduced, so consistent extractions should be the focus.

A simple farming loop can work well: enter with a lightweight setup, target specific materials, avoid unnecessary pickups, extract, sort your stash, and prepare for the next run.

The absence of player damage gives you more freedom to follow a route without constantly changing direction because another Raider is nearby. You can spend more attention on ARC enemies and resource locations instead.

That makes the test a good opportunity to identify which materials you actually use most and which parts of your normal inventory can be removed.

Avoid the Stash Bug

There is also a known issue involving large and small inventory augments that has allowed some players to push overflow items into an overloaded stash. It is an unintended behavior rather than a legitimate inventory feature.

I would not build your preparation around it. Even if the trick works temporarily, relying on a stash exploit can create unnecessary problems when the goal is to establish a stable farming setup.

Keeping your inventory within its intended limits also forces you to make better decisions about what deserves space.

Make Every Slot Count

The PvE test gives players a chance to approach farming in a much more controlled way. Clean out duplicates, organize attachments, reduce unnecessary ammunition, limit your stored weapons, and reserve open slots for useful materials.

Once the stash is ready, the week-long event becomes much easier to approach as a resource-gathering exercise. Players who need additional equipment for their progression can also use the extra preparation time to consider whether they want to buy ARC Items before starting a series of farming runs.
