How to complete the task

Sources checked 27 Sept 2026

This route connects Customs to Factory through transit. The precision-tools case comes from the Customs laboratory, then goes to Factory’s laboratory storage room.

The current wiki also lists three Scav kills on Factory in the same run; that counter is absent from the data feed. Check your in-game task and finish it if shown before leaving Factory.

Before you start

Plan supplies for both maps and keep the case with you through transit.

Search the Customs laboratory
Check the second-floor storage and experiment rooms. The gallery shows six possible case spots; collect one case.
Use the Factory transit
Travel through the transit near Old Gas Station. A normal extraction followed by a separate Factory raid is not the transit objective.
Stash below the Factory lab
Enter the storage room beneath the laboratory, use the placement prompt and let it finish.
