Every Outpost Location in Arknights Endfield

Outposts scattered across Talos-II represent pockets of civilization struggling to survive in harsh conditions. In Arknights Endfield, these settlements offer far more than narrative flavor—they function as critical economic hubs and expansion sites for your manufacturing empire. Whether you’re generating Stock Bills or need additional construction space, Outposts become essential to your progression.

The first Outpost practically announces itself during your early playthrough, but subsequent locations require more deliberate exploration and quest completion. For players new to base management systems, our Arknights Endfield guides hub covers the fundamentals before diving into advanced Outpost optimization.

All AIC Factory Locations and Unlock Requirements

Six buildable factory locations exist in Endfield’s launch version, with more expected in future updates. Most unlock through story progression, though some require completing side missions that only appear after reaching specific campaign milestones.

PAC/Outpost	Region	Unlock Mission
Valley IV Core AIC	Valley IV — The Hub	Valley Reboot
Refugee Camp	Valley IV — Refugee Camp	Building an Outpost
Infra-Station	Valley IV — Originium Science Park	Outpost: Infra-Station
Reconstruction HQ	Valley IV — Power Plateau	Outpost: Reconstruction HQ
Wuling Core AIC	Wuling — Wuling City	A Breeze Away
Sky King Flats	Wuling — Jingyu Valley	Where Danger Sleeps

The Infra-Station and Reconstruction HQ Outposts won’t appear until you’ve completed specific questlines in their respective sub-regions. Check your quest log regularly—these missions sometimes wait quietly without obvious notifications. After finishing the Paving The Way quest, you’ll have the manufacturing knowledge needed to make full use of these additional sites.

Strategic Uses for Outposts

Outposts serve dual purposes that become increasingly important as your operation scales. First, they function as trading posts where excess production converts directly into Stock Bills. This currency funds gear crafting, PAC upgrades, and countless other progression systems.

Second, Outposts provide precious real estate for secondary production facilities. Your main PAC eventually runs out of space when you’re juggling multiple complex manufacturing chains. Outposts solve this problem by hosting specialized production lines away from your primary factory.

Ideal Production Lines for Outposts

Consider dedicating Outpost space to these operations:

• Agricultural plots for farming operations that require minimal oversight
• Component manufacturing like Origocrusts, Amethyst Parts, and Ferrium that feed into larger production chains
• Resource-specific refinement when certain materials cluster in particular regions

By distributing production across all available Outposts, you maintain efficiency in your main PAC while maximizing total output. This becomes particularly important when crafting aerospace materials or managing battery production across multiple sites.

Outpost Prosperity and Leveling System

Every trade transaction with an Outpost generates Prosperity points. Accumulate enough Prosperity and the Outpost levels up, increasing its Stock Bill cap. Higher caps mean you can conduct larger trades per cycle, directly boosting your income potential.

There’s a catch: Outposts won’t level beyond their initial tier until you complete associated Outpost-specific quests. These missions typically involve helping the settlement with construction projects, resource deliveries, or security concerns. Prioritize these quests when they appear—the economic benefits compound rapidly.

Think of Outpost leveling as a long-term investment. Early trades might feel modest, but as caps increase and your production scales, these settlements become significant revenue streams. Players focused on economic optimization should review our blueprints guide to streamline production feeding these trading relationships.

Regional Development Benefits

Outpost prosperity contributes to broader Regional Development metrics, which unlock increasingly valuable perks:

• Enhanced ore purity means better yields from mining operations
• Increased Regional Stock Bill caps allow larger economic transactions
• Higher zipline limits improve traversal efficiency across territories
• Expanded combat facility placement for better defensive infrastructure

Regional Development milestones also shower you with rewards. Expect Headhunting Permits and Oroberyls—both currencies that fuel Endfield’s gacha system—as you hit progression benchmarks. These freebies add up substantially over time, potentially saving you significant resources when building your ideal roster.

The system creates a positive feedback loop: trading with Outposts generates income, which funds better production, which enables more trading, which pushes Regional Development higher. Players who invest early reap compounding benefits throughout their playthrough.

Maximizing Outpost Efficiency

Smart Outpost management involves more than just unlocking locations. Consider these optimization strategies:

Regional specialization works because Stock Bills remain region-locked. Focus Valley IV Outposts on materials abundant in that region, then replicate successful designs when establishing Wuling operations. This prevents resource bottlenecks caused by trying to ship materials between regions.

Production timing matters when juggling multiple Outposts. Stagger your manufacturing cycles so different sites finish production at different times. This smooths out your trading schedule and prevents long periods where you’re waiting for materials to finish processing.

Quest completion directly impacts earning potential. Those Outpost-specific missions aren’t just narrative content—they’re economic investments. Completing them unlocks higher prosperity tiers and better Stock Bill caps, so treat them as priority tasks rather than optional content.

For players struggling with inventory management across multiple sites, our Quick Stash guide explains efficient material handling techniques that scale across your entire operation.

Connecting Outposts to Broader Systems

Outpost development intersects with nearly every other progression system. The Stock Bills you generate fund character upgrades, equipment crafting, and facility expansion. Regional Development perks improve combat effectiveness and resource gathering. The manufacturing space enables specialized production that supports your best team compositions.

As you push into endgame content and optimize builds for characters like Laevatain, Endministrator, or Ardelia, you’ll find yourself constantly circling back to Outpost production chains. The materials flowing through these sites directly enable the gear and upgrades that define high-level performance.

Understanding Outposts as economic engines rather than simple trading posts transforms how you approach resource management. Every facility placement decision, every production line design, and every trade transaction becomes part of a larger optimization puzzle that rewards careful planning and system mastery.
