Polygon’s The Last of Us Part 2 Seattle Day 1 – On Foot collectibles walkthrough begins after the Scar ambush. It ends when the crew arrive at the WLF base. There are 1 Artifact, 4 Coins, 1 Workbench, and 1 Safe to find in On Foot.
Kentucky Quarter Coin location
On Foot Coin 1 of 4
After the Scar ambush, enter the warehouse and take an immediate right. Walk to the folding table and score the Kentucky Quarter.
Massachusetts Quarter Coin location
On Foot Coin 2 of 4
After pushing into the Garden Center, walk down to the far left corner. Grab the Massachusetts Quarter at the checkout below the “Garden Center” sign. It should be at a diagonal to the Aisle 16 sign.
Workbench 1 location
On Foot Workbench 1 of 1
After rappelling into the building and moving the fallen shelving to let Mel in, advance to the next room. Run straight until you see a white refrigerator to your left. Next to it, there’s a Workbench.
Ohio Coin location
On Foot Coin 3 of 4
In the warehouse housing the boat, boost Mel up when prompted and she’ll unlock the second story door giving you access to the ladder. Stay on the platform where you found it, and place the ladder along the wall to gain access to the smaller third floor. Here you’ll find a gray card table. The Ohio Coin is on the left corner, on the side closest to you.
Indiana Coin location
On Foot Coin 4 of 4
After climbing down from the roof with Mel, approach the trailer in the middle of the lot. Throw a brick through its window, then climb through. In the next room over, investigate the computer desk to find the Indiana quarter.
WLF Gun Cache Note Artifact location
On Foot Artifact 1 of 1
Opposite the desk where you found the Indiana Quarter, on the filing cabinet in front of the coffee pot, pick up the Paul to Marta letter artifact, with a reference to a lockup and a hint that “the big win” is the combination.
Safe 1 location
On Foot Safe 1 of 1
To open the safe referenced in the Paul to Marta letter Artifact, you’ll need to ignore the most obvious clue in the trailer. While, on the framed fishing picture, there’s a prominently displayed date that fits the combination 08-15-12, it doesn’t unlock the safe. Instead, look at the numbers, circled in red, on the lottery ticket displayed next to the computer desk. You’ll probably need to physically get off the couch and walk over to your TV to read the winning numbers.
I’ll save you the trouble. The combination is 17-38-07. Exit the trailer and cross over to the MS Corporation Soft Drink Distribution Center. The door’s locked, so walk over to the side of the building that faces the train tracks and slip inside through the crevice in the wall. The safe is located on your left as you shimmy in. Punch in the combo and a few packs of ammo are yours.
