Endfield AIC guide: Optimize your factory fast
By Liam STIM, 48 years old — author of this Endfield AIC guide
Endfield AIC guide: Overview
Endfield AIC guide: Arknights: Endfield adds a fresh layer to its gacha formula. Beyond characters and combat, it introduces a production system called AIC. This system is not a simple add-on: it shapes progression, resource management, and long-term play. Players who master AIC cut down farming time and gain a steady advantage. That leaves more time for events and banners. I write guides because I value clear steps and practical setups. This guide walks you through everything from your first blueprints to late-game optimization. It is aimed at players who want to build efficient loops and avoid wasting resources. For a broader strategy connecting AIC to the economy and live-service operations, see the complete player guide.
What is the AIC factory, and why does it matter?
Core concept in this Endfield AIC guide
AIC is a modular factory. You place modules that extract, refine, and assemble resources. Each module has inputs and outputs. Some modules run continuously, others need maintenance or rare materials. The factory connects to your base and shipping systems. It can produce upgrade materials, crafting parts, and event tokens. Mastering AIC shortens your path to gear and reduces reliance on random loot. This Endfield AIC guide breaks down every step needed to build this factory efficiently.
Why this changes progression
Most gacha games focus on combat loops. Endfield adds a production loop on top. This loop rewards planning: a well-run factory delivers predictable output. That predictability is crucial for planning banner pulls and finishing time-limited events. It also opens up new playstyles. Some players favor factory optimization, while others spend more time on combat than production. Both approaches work. What matters is understanding the trade-offs involved.
Early-game goals
During your first week, focus on three goals: unlocking basic extractors, establishing a stable fuel supply, and building a refining chain that turns raw ore into upgrade materials. These steps give you breathing room. That room lets you avoid repetitive, tedious tasks. You can also test module placement without setting back your progress.
Initial setups: blueprints, resource loops, and bottlenecks
Early blueprints to prioritize
Start with these modules: an ore extractor, a basic refinery, a storage unit, and a fuel generator. The extractor supplies raw material, the refinery processes it, storage smooths out production spikes, and the generator keeps modules running. Place them close together to cut transport time, since long transport reduces throughput.
How resource loops work
A resource loop is a chain of modules that feed one another. A simple loop looks like this: an extractor produces ore; a refinery turns the ore into ingots; an assembler uses the ingots to craft parts; the parts feed a workbench that produces upgrade materials. This process repeats. The goal is to balance inputs and outputs so no module sits idle for too long.
AIC resource flow
[extractor] -> [refinery] -> [assembler] -> [workbench] -> output
Common bottlenecks and fixes
Power shortages: upgrade your generator or add a secondary fuel line. Transport delays: shorten distances or add conveyors. Storage overload: increase storage or reduce production. Module mismatches: adjust module tiers so outputs match inputs. Small early fixes prevent major slowdowns later on.
Mid- and late-game automation: scaling and meta
Scaling principles
Increase capacity through replication, not by overpowering a single module. Duplicate efficient chains. Two balanced chains outperform one oversized chain. Use parallel lines to boost throughput. Keep an eye on resource consumers. Events often require specific materials. Where possible, dedicate one line to event-related items.
Meta considerations
Some modules have synergies. For example, a catalyst module boosts refinery output when paired with a heat exchanger. These synergies change the optimal setup. Check the patch notes. The meta shifts as new modules arrive. Adapt quickly. Players who test new combinations early gain an edge during time-limited events.
Mid-game blueprint example
| Module | Level | Role | Notes |
|---|---|---|---|
| Ore extractor | 3 | Capture | Place near the resource node |
| Refinery | 4 | Convert | Pair with a heat exchanger |
| Assembler | 3 | Combine | Two parallel lines |
| Storage | 2 | Buffer | Avoid overflow |
| Generator | 3 | Power | Add backup fuel |
Practical blueprints and step-by-step builds
Starter blueprint
Place an extractor, a refinery, an assembler, a warehouse, and a generator close together. Connect them with short conveyors. Set the refinery to a low throughput to avoid overfilling the warehouse. Let the system run for 24 hours. Check production. Adjust refinery speed if the warehouse fills up too fast. This starter blueprint is a recommended foundation for any Endfield AIC guide.
Mid-game blueprint
Duplicate the starter chain. Upgrade the refinery to level 3. Add a catalyst module to one chain to test synergy. Keep the other chain as a baseline. Compare output after 48 hours. The chain with the catalyst should show higher output per raw material unit. If it does not, check power consumption and transport.
Late-game blueprint
Set up three parallel chains. Dedicate one to event materials. Use advanced storage with priority routing. Add automated maintenance drones to cut downtime. At this stage, focus on uptime and event readiness. Even short downtime gets costlier as demand grows.
Tips for efficiency and long-term planning
Daily routines
Check the factory once a day. Clear bottlenecks. Collect storage. Restart the production chain if needed. Small daily actions prevent major delays.
Resource allocation strategy
Prioritize upgrade materials for your main operators. Use factory output to fill gaps, not to replace core production. Build up a reserve of fuel and rare catalysts. These reserves help you handle sudden event-driven demand.
Team and community play
Share your blueprints in your guild or on Discord. Test different variants and track output. Community testing speeds up the discovery of best practices. Keep a simple log: note module tier, layout, and average hourly output.
Endfield AIC guide: Conclusion
Mastering AIC is a long-term investment. Start simple. Build balanced chains. Duplicate what works. Keep reserves for events. Follow patch notes and adapt. The factory rewards planning more than time spent. If you want a broader strategy linking factory output to banners and live-service operations, see the complete player guide for a deeper breakdown.
