If you’ve been playing Arknights: Endfield, you know the feeling: you’re deep in a mining operation on Talos-II, your manufacturing lines are humming, and suddenly—clunk. Your inventory is full. You can’t pick up that rare Polymerization Catalyst or the LMD crate you just fought a boss for. It’s a nightmare scenario that halts progress in its tracks.

I’ve been there. When I first started managing my outpost, I underestimated how quickly resources pile up. In Endfield, storage isn’t just a number; it’s the backbone of your economy. If you can’t store materials, you can’t build structures. If you can’t build structures, you can’t advance.

In this comprehensive guide, I’m going to walk you through exactly how to increase storage capacity in Arknights: Endfield. We’re not just talking about building a shed; we’re covering advanced management strategies, grid optimization, and credit-saving tips that most players miss. Whether you are struggling with Basic Materials or high-end Rare Parts, this guide has you covered.

How to Increase Storage Capacity in Arknights: Endfield

Now, let’s dive into the nitty-gritty. Managing your inventory in Arknights: Endfield is different from the original Arknights. Here, you are managing a physical base, and your storage is tied to the buildings you construct.

Understanding the Storage Mechanics

Before you spend a single credit, you need to understand how the game calculates your limits. Arknights: Endfield separates storage into two main categories:

Outpost Inventory (Physical Storage): The limit imposed by your buildings (Depots).
Backpack Inventory (Character Limit): The limit of what your operator carries in the field.

This guide focuses on the Outpost Inventory, as that is the bottleneck for resource gathering.

Step 1: Building and Upgrading the Storage Depot

The primary method for increasing space is through the Storage Depot. This is the first building you should prioritize after your Command Center.

Prerequisites:

Reach Commander Level 3.
Unlock “Infrastructure” in the Tech Tree.
1,000 LMD (Initial cost).

Step-by-Step Process:

Enter Build Mode: Press ‘B’ or click the construction icon on the bottom right of your HUD.
Select Infrastructure: Navigate to the “Logistics” tab.
Place the Depot: Select “Storage Depot”. Pro Tip: Do not place this in a corner. You will be building multiple of these, so place it centrally to minimize travel time for your logistical drones.
Confirm Construction: Wait for the timer (usually instant for Level 1).
Upgrade for Capacity: Click on the built Depot. You will see an “Upgrade” button.
- Level 1: Cap 1,000 units.
- Level 2: Cap 2,500 units (Cost: 2,000 LMD + Basic Plating).
- Level 3: Cap 5,000 units (Cost: 5,000 LMD + Reinforced Beams).

Note: As you level up the Depot, it physically gets larger. Ensure you have space around it for the expansion footprint, or you won’t be able to confirm the upgrade.

Step 2: Constructing Auxiliary Warehouses

Once your main Storage Depot hits Level 4, the upgrade costs skyrocket. This is where the Auxiliary Warehouse comes in. This is a game-changing feature that many guides overlook.

Unlike the main depot, the Auxiliary Warehouse is a “flat” building that provides a massive boost to a specific type of material.

How to build them:

Open Build Mode.
Go to the “Special” tab.
Select Material Silo (this is the in-game name for the specialized warehouse).
You will be prompted to choose a specialization:
- Ore Silo: Stores Raw Ores (Manganese, Titanium, etc.).
- Component Silo: Stores crafted parts (Gears, Circuits).
- Biological Silo: Stores consumables and biological agents.

Why this matters: By building a Component Silo, you increase your cap for only components, often freeing up general space in your main depot. It allows for a much higher total storage capacity than upgrading the main depot alone.

Step 3: Grid Layout and Optimization

Are you running out of physical space to build the storage units? In Arknights: Endfield, your buildable area is limited by your “Base Energy Grid.”

If you can’t place more warehouses, your Base Energy might be maxed out. Here is how to fix it:

Upgrade the Power Plant: Ensure your Power Plant is at least two levels higher than your Storage Depots.
Dismantle Old Decorations: Those trees and rocks you placed for aesthetics? They consume grid energy. Remove them until your base is fully operational.
Use Verticality: Some storage modules can be stacked or placed on elevated terrain. Check the blueprint for “Elevation Allowed” tags. This effectively doubles your storage density in one area.

Step 4: Managing Resources (The “Spring Cleaning” Method)

Sometimes, increasing the limit isn’t about building more; it’s about managing what you have. I personally hit a wall where I had 10,000 units of “Rusty Scraps” clogging my inventory.

Auto-Dismantle Feature:

Go to Settings > Gameplay.
Look for “Auto-Dismantle Grey/Green Items”.
Toggle this ON.

This setting automatically converts low-tier loot (Common rarity) into “Universal Components” or LMD immediately upon pickup. It keeps your inventory clean without you having to manually click “Sell” every 5 minutes.

Smart Crafting to Save Space:

The “3-to-1” Rule: Generally, 3 Tier-1 materials can be crafted into 1 Tier-2 material. This reduces your inventory count by 66% instantly while retaining value.
Example: If you have 300 Iron Ore, craft it into 100 Steel Plates. You save 200 inventory slots.

Step 5: Premium Solutions (Last Resort)

If you are a whale (big spender) or simply desperate during an event, there is a monetized option.

The Storage Capsule:
This is a premium item purchasable from the Credit Store or the Premium Shop.

Effect: Adds a permanent +500 slots to all inventory types.
Price: 5 Originium Prime (or equivalent premium currency).
Verdict: Only buy this if you are at Base Level 10 and have maxed out all free buildings. It is efficient, but not necessary for free-to-play players.

Advanced Strategies for Resource Management

Now that we have the basics down, let’s talk about the “Pro” strats. This is the stuff that separates the casual players from the top-tier Commanders.

The “Just-in-Time” Logistics System

In real-world manufacturing, “Just-in-Time” means receiving goods only as they are needed. In Arknights: Endfield, you can simulate this by using Request Contracts.

Instead of storing 5,000 units of lumber, only store what you need for your current project.

Check your manufacturing queue.
Calculate exactly how much material you need.
Set a “Request Order” to gather that amount.
Pause all automated mining/gathering once the quota is met.

This keeps your storage fluctuating around 50% capacity, giving you a buffer for loot drops without expanding unnecessarily.

Drone Routing Efficiency

Did you know that your Logistics Drones affect your storage perception? If your drones are slow, your factories will choke because they can’t move finished goods out of the machine into the storage.

Optimization: Build “Drone Hubs” near your Storage Depots.
Effect: This doesn’t increase the hard cap, but it increases the effective speed of clearing temporary buffers (like factory outputs), making it feel like you have more space.

Troubleshooting Common Issues

“Storage Full” Error despite having space:
This is a common bug reported on the Official Discord. It usually happens when you have a “Storage Request” active.

Fix: Cancel all active Requests, pick up the items manually, then re-issue the request.

Can’t Upgrade Depot (Missing Resources):
You have the LMD, but the button is greyed out.

Cause: You likely lack the Construction Templates.
Fix: Templates are earned by exploring the map and opening “Supply Chests” in the fog of war. Go explore! You haven’t unlocked the blueprint yet.

Platform-Specific Information

For PC Players

If you are playing on a high-end PC, ensure your SSD has space. Arknights: Endfield saves local cache files for base rendering. If your actual hard drive is full, the game might glitch and fail to load your upgraded storage visuals, though the data usually remains safe.

For Mobile Players

On mobile, storage management is even more critical due to battery life and heat. Constant background syncing of a massive inventory drains battery. Using the “Auto-Dismantle” feature (mentioned above) is actually a battery-saving strategy because it reduces the number of database entries the game has to track.

Frequently Asked Questions

Does increasing storage increase my Base Power Rating?

Yes. Building structures, including Storage Depots, contributes to your total Base Power. A fully upgraded storage network can add several hundred points to your rating, which is helpful for ranking in the Territory Wars.

What happens to my items if I demolish a Storage Depot?

They are safe, but inaccessible. If you destroy a Level 5 depot, the items currently stored in it are moved to a “Limbo” state. You cannot use them, craft with them, or see them until you build a new storage depot with sufficient capacity to hold them again. Never demolish a depot if you are near your total cap!

Is there a limit to how many Auxiliary Warehouses I can build?

Technically, no. However, you are limited by your Base Energy Grid. Each Warehouse consumes energy. Once your grid is full, you must upgrade your Power Plant to build more warehouses.

Can I buy storage with LMD?

Indirectly. You use LMD to construct and upgrade the buildings. However, you cannot just pay LMD to “unlock” slots like in some MMOs. You must physically place the building.

Do items expire?

No. Unlike some survival games, materials in Arknights: Endfield do not rot or expire over time. Feel free to hoard those Rare Parts for the right operator.

Conclusion

Running out of storage in Arknights: Endfield is a rite of passage. It shows that you are playing actively, gathering resources, and building up your outpost. By following this guide, you now know that the solution isn’t just “building more”—it’s about building smart.

Focus on upgrading your main Storage Depot first, utilize Auxiliary Warehouses for specific resource types, and keep your inventory clean with the Auto-Dismantle feature.
