Below is a guide on the 5 artifacts, 1 journal entry, 3 trading cards and 1 workbench that can be found during The Tunnels chapter in The Last of Us Part II.
Artifact – Subway Note
As part of the story, you and Dina will need to open a train car door. Head through the train cars to the very end to find the artifact in the last train car on a wall next to a window.
Trading Card – The Imp
After entering a train car to escape some Clickers as part of the story, follow the path further down to exit the train car then follow the traintracks towards an open doorway emitting red light. This card can be found alongside a blue train car to the left of the doorway. It will be underneath the train car door next to some trash bags.
Workbench
After entering the red lit room, you will need to climb a ladder on the right side to reach a walkway containing a rope. Head to the right side of the walkway to find a door leading to a storage room that contains this workbench.
Journal Entry
After defeating a new enemy, inspect the body to receive a new journal entry.
