Combat, factories, exploration, and how they all connect. Here is what you need to know before your first session.
Arknights: Endfield combines real-time squad combat with a factory automation system, and at first glance it can feel like two different games pushed together. Once you understand how the systems connect, though, everything starts to click in a satisfying way. This guide covers the core mechanics so you go in knowing what you are doing rather than spending your first few hours confused by systems the game does not explain very well.

How combat works
You control a squad of four operators in real-time. You directly control one at a time and can switch between them instantly mid-fight. Each operator has basic attacks that build toward a finisher, plus skills that charge during combat.
The key system to understand early is combos. When your operator’s combo meter fills, they can trigger a combo skill. Here’s a simple way to think about it: the combo skills are where most of the real damage happens, and they synergize between teammates. If you trigger one operator’s combo skill, it can chain into another operator’s automatically, creating a burst window that melts through enemy health. Most new players miss this at first because the basic attacks feel fine on their own, but learning to set up combo chains is what separates smooth play from struggling.
Elemental reactions are the other layer to understand. Different operators apply elements like Heat, Cryo, Physical, and Electric to enemies. When you stack the right combinations, reactions trigger: Combustion from Heat overlap deals massive AoE, Solidification from Cryo plus Physical creates damage windows for physical dealers. Once you understand this system, everything makes more sense about why certain operators are paired together in team recommendations.
How the factory system works
The Automated Industry Complex (AIC) is Endfield’s most unique feature, and the game introducs it gradually rather than all at once. The basicly idea is that you build automated production facilities in the open world that generate resources while you are offline and between sessions.
You place mining extractors at resource nodes in the world. Those extractors feed into processing machines via conveyor belts and ziplines. Processed materials flow into storage or directly into crafting stations. Your factories run continuously, and when you log back in, your stockpiles have grown.
The practical reason to engage with this early: most of the gear you want to craft requires factory-produced components. The faster you establish even a basic production chain, the faster your team gets stronger without any additional grinding. You do not need to build anything elaborate at first. A simple extractor connected to a processor is enough to start the material loop.
Later in the game, this becomes much more important as gear crafting scales in complexity. Players who ignored the factory in the early hours tend to hit a wall when they need upgrade materials that require multi-stage production chains.
Exploration and how it feeds everything else
Talos-II is organized into semi-open regions. Each region has resource nodes you can use for your factory, hidden collectibles that reward exploration points, and obstacles that require specific tools or progression milestones to unlock.
The connection between exploration and your factory is direct. New regions mean new resource types, which unlock new production chains, which enable better gear. The world is designed to make exploring feel productive rather than optional. When you find a new ore deposit in an area you have not fully mapped, that is a potential upgrade to your factory network and therefore to your combat effectiveness.
Environmental puzzles and locked areas give you reasons to return to earlier regions as you unlock new traversal tools. The drone you get in the Wuling region, for example, opens up elevated areas you could see but not reach on your first visit. This kind of design rewards thoroughness without forcing it.
The loop in practice
Combat unlocks story progression and opens new regions. New regions provide factory resources. Factory resources enable better gear. Better gear makes combat smoother and harder content accessible. The three systems reinforce each other so that engaging with any one of them feeds back into the others.
If you’re just starting out, here is what matters most: build your first factory chain early, learn the combo system before you need it in harder content, and explore each region reasonably thoroughly before moving on. You do not need to optimize anything in the first few hours. The game is designed to teach you by doing.
