This guide covers Automated Industry Complex (AIC) in Arknights: Endfield. Includes how to switch AIC Mode, how to automate, and the factory system list and functions in AKEF.

AIC Factory Flow and Operation
Switch to AIC Mode

To use the AIC functions, you must first switch from Explore Mode to AIC Mode. If you are near a PAC (Core AIC Area), the mode will switch automatically, so no manual change is required.
Open the Facility List and Construct
After switching to AIC Mode, open the Facility List from the AIC Operation Menu. Select the AIC Factory facility you want to construct, then press 'Construct' to complete the process.
AIC Factory Placement and Use
Switch to AIC Mode

To use AIC features, first switch from Explore Mode to AIC Mode before placing facilities.
Select a Facility from the Facility List
After switching to AIC Mode, open the Facility List from the AIC Operation Menu to continue.
Switch Tabs to Place the Facility
Select the facility you want to place from the list, switch the tab from 'Construct' to 'Placement', then press 'Place'.Check the placement preview, and press 'Confirm Placement' at the desired location to complete the setup.
Tips! | When selecting a placement location, you can move your character to extend the placement range and install the facility at a greater distance. |

Rotating the Facility
During placement, you can rotate a Facility by pressing the corresponding rotation key. Rotation is only available while placing the facility. To change the orientation of a facility that has already been placed, you must store it and place it again.
Connect to Depot via Conveyor Belts

When producing items, connect the line in this order: Depot → Sub-PAC's Output Port → Destination (e.g. Smelter). If placed correctly, the facility will be highlighted in white. Next, connect a 'Transport Belt' from the destination's (e.g. Smelter) Output Port → Sub-PAC’s Input port (Depot) to complete the production line.
Tips! | Once you’re familiar with the system, optimize your setup by connecting the 'Transport Belt' while accounting for both transport speed and facility production speed. |
|---|
Stash (Removing) Facilities

From the AIC Operation Menu in the bottom-right of the screen, select 'Stash Mode', aim your view at the facility you want to store, and press the corresponding key. The stashed facility will be returned to your Toolbox.
Connected Facilities Remain

Facilities and items are not lost when stored. Connected facilities, such as the 'Transport Belt', will remain in place but stop operating. Once the required facilities are placed and reconnected, they will resume operation.
Register to Hotbar for Easier Placement
For frequently used facilities, open your 'Backpack' from the System Functions Menu and register the Facility to the Hotbar. The Hotbar serves as a shortcut, allowing faster and more convenient placement of registered facilities.
What to Do If You Don't Understand the AIC
Basic AIC Plan Simulation
The Automated Industry Complex (AIC) is complex, so the fastest way to learn it is by practicing the controls in the 'Simulation'. You can also earn rewards, so it’s recommended to try building a factory in the 'Simulation' first.
The Content is Practical and Easy to Learn

Upon entering the 'Simulation', the functions and usage of each facility are explained. Similar to the Main Mission, objectives are displayed on the left side of the screen, so proceed by completing each task step by step.
You Can Retry Anytime
If you’re unsure about an operation, you can re-enter the same Simulation as many times as necessary.
Access via AIC Factory Plan

You can also enter the 'Simulation' from the AIC Factory Plan screen, which is accessed via the icon on the left side of the screen. Select the content you want to research, then choose 'Guides.'
Use Available Blueprints Once Unlocked
As you progress through the game, Blueprints will be unlocked. You can refer to other players’ Blueprints, so use them if you get stuck.
