To complete the Node mission reported as “Repair any shared facility 1 time,” find another player’s shared facility, interact with it, and choose Repair if that option appears. Confirm the materials shown in the game. A successful repair is reported to complete the objective, but shared ziplines may behave differently: the developers announced automatic repair while using them, and the announcement does not confirm whether that change has shipped.
Repair a shared facility
- Find a facility built by another player. Look for a shared structure in an open-world region, rather than a structure in your personal base or one belonging to the story. A January 25, 2026 walkthrough lists zipline pylons, power relay nodes, logistics or transport structures, and utility facilities as examples. NerdsChalk’s walkthrough does not establish that every facility type can be repaired for this objective.
- Travel to it and interact. Approach the structure and follow the on-screen prompt to open its facility menu.
- Choose Repair if it is offered. Check the required materials shown in the current interface, then confirm the repair if prompted.
- Check the Node mission. The walkthrough reports that one successful repair completes “Repair any shared facility 1 time.” If no Repair option appears, try another shared facility; the structure may not need repair, or the current interaction may differ.
The walkthrough describes the repair as using basic in-game resources rather than premium resources, but exact current costs have not been confirmed by an official source. Use the material requirement displayed in-game rather than relying on a fixed cost.
What if a shared zipline has no Repair option?
On May 23, 2026, the Arknights: Endfield Team announced: “Shared Facility Repair Optimization: Shared zipline facilities will now be automatically repaired while you use them.” The notice presents this as planned content in an early preview for the “Sketches of Lost Heirlooms” version. It does not state the release version or confirm that the change is live. Read the developer communication.
Because the announcement concerns shared ziplines specifically, do not assume automatic repair applies to every shared facility. Follow the current in-game prompt: use Repair where the menu offers it, and if a zipline has no such option, try using it and then check whether the Node mission updates. The reviewed sources do not establish the current completion trigger for ziplines or whether using one completes this mission.

A March 12, 2026 third-party summary of version 1.1 documents other shared-facility changes, including removing other players’ shared facilities from the map and distinguishing shared from personal zipline styles. It does not explain the repair flow. Read the version 1.1 notes.
The manual steps above come from a January 2026 walkthrough; the later official announcement describes an optimization but does not confirm its release. Neither source establishes the exact game version or region for the current repair behavior. The game’s live interaction prompt is the best guide to what is available at your facility.
