The Medium has a number of collectibles for you to gather. One of those are the Groundskeeper Postcards, and finding all 11 nets you the secret All That’s Left Unsaid achievement, which is worth 40 Gamerscore. However, you need to collect them all in a single playthrough, so follow our guide to ensure you don’t miss any.
Niwa Says Hello
Look at the front gates, to the resort. Head into the guard’s office after the motorcycle cutscene and look for the postcard on the floor in a suitcase.
You find this postcard as you search for an item to help and gain entry to the hotel building. Find the car above on the left side of the car park. Interact with it to grab the postcard from the seat.
In the hotel lobby, approach the locked gate at the far end. But before you reach it, turn right into a small waiting area. Look for a small table — on it is a postcard surrounded by cigarette stubs.
Search in the swimming pool changing rooms. After you squeeze through a gap in the wall, walk around to the room’s exit. Before you leave, look right for a stack of boxes with the postcard on top.
A Scenic View
Find the next one during the sequence where you have to find two spirit face masks. After you return to the real world through the mirror, grab the examination room key from the floor by a trash can. Open the door, take a right, and follow the path to a cigeratte trash can. The postcard is on it.
You’ll find the next postcard following the Child Eater cutscene. Walk down the steps onto a narrow pathway. At a junction, take the left path to find the postcard on a bench.
Go back on yourself and follow the path to a lookout area with a telescope. The postcard is on a bench next to it.
Harder and Harder
On the branching path in the forest, take the left trail. The postcard is on a bench.
Whispers in the Dark
Find this one after you encounter the dog and have to follow it. At a junction, take a path to the right that leads to the river. The postcard is on a bench behind a bush.
A New Companion
Before you inspect the tent at the campsite, walk towards the fire that is going out. The postcard is on a bench just right of it.
Check inside the tent next to Frank’s dead body. Look next to his boots for the postcard.
