In Sons of the Forest, you will need to find the golden armor to head to the final cave.
You can also get the katana and the putter / golf club in the same building.
Here’s how you can find the golden armor, katana and putter (location) in Sons of the Forest.
Cave entrance location
To find the golden armor, katana and putter, you have to find the same cave.
The cave is located near a big lake just below the snowy mountain. You can look at the GPS in the image below. It’s the green blip near the lake.
Enter the cave and proceed ahead.
Use the keycard to open the door.
At one point, you’ll see a cutscene.
How to find the putter
You will find the putter in one of the rooms on the first level you’re in. There are also golf balls in the room.
How to find the katana
You will then find the katana on the lower level in one of the rooms as well.
Golden armor location
After the katana’s room, continue ahead and look for the other rooms. The golden armor is on the couch in one of the later rooms.
Exit the area
You can then exit the area using the keycard door. Follow the cave until you exit.
