The Best Mega Base Blueprint You Need for Arknights: Endfield

Hello Endministrators!

If your base currently looks like a pile of tangled wires and stalling assembly lines, don't worry—you’re definitely not alone. Building a "Mega Base" in Arknights: Endfield is a massive undertaking, but once the logic clicks, the game becomes a lot smoother.

Instead of just throwing random codes at you, let's break down why this specific blueprint is a game-changer and how to manage it so your resources don't hit zero.

What Makes This the “Best” Blueprint?

This Mega Base setup is built around three core ideas:

• Long-term scalability – It works now and gets better as Regional Development levels increase.
• Resource stability – Especially important for Ferium Ore, which is the main early-game bottleneck.
• Low maintenance – Fewer rebuilds, fewer headaches, more time actually playing the game.

Instead of chasing perfect ratios early on, this blueprint accepts early inefficiencies and turns them into advantages later.

 

Factory Layout Philosophy

The factory area intentionally leaves some open space. That space isn’t wasted—it’s reserved for:

• Tier 2 items, especially Blue Batteries
• Flexible production lines that can be repurposed later
• Trade-oriented manufacturing to keep Outpost exchanges flowing

Rather than stuffing every tile with machines, this layout prioritizes flow. Empty space now prevents painful demolitions later.

 

Ferium Ore: The Real Bottleneck (and How This Blueprint Solves It)

If you’ve played for more than a few hours, you already know the problem:

Ferium Ore demand outpaces supply.

Early Game Reality

• Even with miners placed on every Ferium node, consumption still exceeds production.
• This is normal. Don’t panic and don’t overbuild.

The Fix: Regional Development Level 11

Once Regional Development reaches Level 11, a major upgrade kicks in:

• Origin Loadspring and Power Plateau mineral beds
• Upgrade from Low-Purity → High-Purity
• Result: Significantly higher ore yield per miner

This blueprint is designed specifically to bridge the gap until that point without collapsing your supply chain.

 

Smart Production Management (Very Important)

Until Ferium stabilizes, selective shutdowns are your best friend.

What to Do:

• Temporarily turn off duplicate production chains
• Example:

Battery production often has two parallel chains

• Disable one
• Cut Ferium usage immediately
• Re-enable later when supply catches up

This approach keeps the base functional without starving critical systems.

 

One More Hidden Mining Spot (Power Plateau)

There is one remaining Ferium mining spot in the Power Plateau area that players often miss.

• It’s locked behind the Wulfgard story quest
• You do not need to finish the entire quest
• Simply:

• Progress until the area is accessible
• Unlock the gate
• Exit the quest if you want

This alone can noticeably ease mid-game pressure.

 

Expansion Planning: What Comes Next?

This Mega Base is not the end—it’s the foundation.

• Designed to transition smoothly into Wuling content later
• Modular layout makes regional expansion cleaner
• Minimal rework required when new zones unlock

In short: build once, benefit forever.

 

Blueprint Codes

EU / NA Blueprints

Buck Capsule A (EFO01893u6u8aE127UI73) - Produces Buck Capsules used for personal use and trading with outposts. Starting production early ensures you can supply both Valley Batteries and Buck Capsules once unlocked. This setup works in any outpost as long as your AIC and outpost are fully upgraded, making it a flexible and essential production line for mid- to late-game trading and crafting.

Base A – Use the code EFO01O3E2u2Oo7I79oe4 to place this base at the very edge of your AIC plot.

Base B – Located to the left of Base A, this base produces HC Valley Batteries and Sand Leaf Powder. Its compact layout makes efficient use of limited space while supporting power generation, trading, and material distribution. Use the code EFO0136uI1I302aO0579 to place it.

Base C (EFO01o08393o1O6uIieO)– Produces Crystal Parts for Zipline Towers and Steel Parts for Turrets. Proper placement near transport belts ensures efficient space usage, supporting mid- to late-game infrastructure.

Flower Loop (EFO019A61i197ue15uI2) - Infinite loop; supplies Mega Base C and D; balances production and minimizes wasted space.

Base D (EFO01893u6u8aE19UI73)  – Dedicated bomb production with four lines. Bombs are used for personal use and delivery tasks, efficiently occupying minimal space while supplying depot requirements.

Base E (EFO01eE7U2Ue5047oAi8) – A massive plant production zone producing Sand Leaf and Buck Flowers. Its eight self-looping units ensure continuous supply for batteries, bombs, and other recipes, with excess routed to storage or the depot.

Conclusion

This blueprint focuses on comfort, consistency, and long-term scalability. When applied correctly, it significantly reduces early-game pressure, keeps mid-game resource spikes under control, and makes late-game expansion smooth and painless.

Build smart from the start, and Endfield will reward you with a stable, efficient base that grows alongside your progress. Good luck out there, and enjoy building a base that serves you well throughout the game.
