Arknights: Endfield Base Optimization: Mastering Industries and Factories

2026-01-30

Arknights: Endfield challenges you with more than just battles and gacha pulls. At the heart of your growth is the Factory system—your economic engine for advancement. To help you master it, we’ve created this complete guide to optimizing your bases and maximizing factory efficiency from the ground up。

What Is The Factory System?

A cornerstone of gameplay, the Factory System is Arknights: Endfield’s dedicated industrial management mechanic. Here, you will construct and optimize production lines to manufacture valuable goods. These products are fundamental to your progression, serving as a primary source of income through trade and as key components for crafting advanced equipment and items.

Building an optimal factory is about balancing high-value output with minimal resource input. Your production efforts should focus on critical endgame items: Blood Capsules (Operator healing), Batteries (factory power), and Cryston Components (gear crafting and augmentation). Without a sustainably efficient factory, you simply cannot advance to or compete in the game’s endgame content.

Main And Sub Bases

Industrial operations are structured within Main Bases and Sub Bases located in major regions. In the current version of the game, Valley IV contains one Main Base supported by three Sub Bases, while Wuling features one Main Base and one Sub Base.

The core distinction between a Main Base and a Sub Base lies in their scale and upgrade potential. Main Bases offer larger building areas and access to more advanced upgrades. Sub Bases are comparatively smaller with limited development options.

Therefore, the optimal strategy is to designate your Main Base as the primary hub for manufacturing high-value end products. Sub Bases should then function as supporting infrastructure, focused on producing raw materials and components to supply the main production line.

Initial Setup: Mining, Agriculture, and Power

To begin construction, you must first establish resource networks. This is done by placing Electric Relay Towers across the map. You must then manually connect these towers to each other and to resource nodes (such as ore veins), forming a pipeline that delivers raw materials to your bases’ depots.

These raw materials, primarily ores initially, form the essential foundation of your entire industrial operation. The majority of factory recipes require these processed basic materials to create usable products.

Beyond mining, you must also produce plants and seeds for complex recipes. While found via exploration, a permanent solution is to build an automated farm by linking 2 Planting Machines with 1 Seed-Picking Machine. Reliable access to large plant quantities is crucial for later-stage production.

Finally, no base can operate without power. Each added Relay Tower and factory machine increases consumption. If demand exceeds supply, all production stops entirely. To avoid this, prioritize building sufficient Thermal Banks to create a stable power surplus before any major expansion.

Core Loop: Depot Level & Economics

Your Depot Level is a central progression metric, raised by exploring and building. Leveling up increases your Depot Bill capacity, unlocks better goods, improves resource income, and grants valuable rewards like recruitment pulls.

To earn Depot Bills, you must use the Stock Redistribution Exchange (unlocked with Sub Bases). Here, you sell products to local depots. The Bills you earn are used to upgrade facilities and buy vital items. Importantly, leveling up each depot relationship allows you to sell more types of goods, creating a positive cycle of production and economic growth.

Planning for Depot Upgrades & Depot Bus

To advance your industrial operations, you must plan for major Depot Upgrades (including area expansions and the Depot Bus). Key facts:

• Unlock Condition: Progress through the main story.
• Currency Cost: Paid with a large sum of regional Stock Bills. Start saving early.
• Core Purpose: These upgrades provide the essential space and logistical capabilities to increase production speed and output, enabling a shift towards more profitable product lines.

Maximizing Income: Stock Exchange & Delivery Jobs

For rapid economic growth, prioritize the Stock Exchange and Delivery Jobs, both unlocked via story progression. The Exchange enables profitable arbitrage by buying low and selling high to other players, quickly amassing Stock Bills. Concurrently, Delivery Jobs offer sizable direct payouts for completing logistics tasks, together forming the most efficient funding pipeline for your late-game upgrades.

Arknights: Endfield Factories Guide – Essential Tips & Tricks

1. Prioritize Base Upgrades

To produce the volume of materials required for endgame, you will need ample space and efficient logistics. Upgrading your bases and Depot Buses should be your top priority, as this expands your production capacity and is foundational to all advanced setups.

2. Utilize Community Blueprints

If designing optimal layouts isn’t your focus, make use of shared blueprints from other players. This can save you significant time and effort, allowing you to focus on other progression aspects like character building.

3. Complete Daily Economic Activities

The Stock Exchange and Delivery Jobs are your most reliable daily sources of Stock Bills, which are critical for funding upgrades. Make these tasks part of your daily routine.
