Below is a guide on the 6 artifacts, 1 journal entry and 4 trading cards that can be found during The Gate chapter in The Last of Us Part II.
Trading Card – Motivator
The card can be found in a bus stop in a pamphlet container on the inner wall. This will be shortly after starting the level when you reach a section with cars in the forest.
Trading Card – The Starfire Kids
When you reach the highway filled with cars in the forest, follow the road under the overpass to reach a construction trailer on the left side of the road. The card will be in the trailer on a bulletin board.
Artifact – Map of Seattle
This can be found in the same trailer as the above collectible in the back room.
Journal Entry
When you reach the military zone with the WLF Trespassers Killed on Sight sign, interact with the sign to receive the entry.
Artifact – Refugee Note
This artifact can be found on a table in the structure to the left of the WLF Trespassers Killed on Sight sign.
Artifact – Infected Infographic
This artifact can be found on a table in the structure furthest from the WLF Trespassers Killed on Sight sign.
Trading Card – Chessmaster & Artifact – Isaac’s Orders
After you climb over the wall, head across the narrow walkway to enter a room with a ladder leading down. If you turn left in that room, you’ll see another ladder heading up. Climb up that ladder to find the card and artifact in the lookout tower on tables.
Artifact – Checkpoint Gate Codes
From the above collectibles, head back down the ladder then take another ladder down to reach the ground floor. The artifact can be found in the military structure straight ahead in a filing cabinet.
Trading Card – Oozer & Artifact – Rooftop Note
After you start the generator and throw the yellow cable over to the other side, head to the other side of the military structure and climb up the cable you just threw over. The card can be found on a table next to a lawn chair on the roof.
