The Last of Us 2 Big Win safe is just one of the various hidden chests and caches squirreled away in this post-apocalyptic world.
It's common to come across secret loot and hidden treasures in a world as expansive as the one in TLOU2. Naughty Dog certainly did their part in giving players a reason to head out and explore the wilderness all around them.
The Last of Us 2 Big Win Safe Code
You'll be able to find the safe while playing through the On Foot part of Seattle Day 1.
Once you leave the building with the hanging boat — exiting from the roof — you'll find yourself standing in front of an old MS Corp. soda distribution plant. Head around the building to find a hole in the wall next to some wood pallets. It's inside this crack that you'll find the safe among other helpful items.
To save you some time, the code for the safe is "17-38-07."
If you want to find the location of the code, look no further than the trailer across from the building. You'll need to break in, of course, but once you do you'll find an artifact called "WLF Gun Cache Not." It's a letter to someone named Marta explaining another person called PaulPS has set the combination of the safe to "the big win."
The Last of Us 2 Big Win Safe
This big win actually refers to a lotto ticket pinned to the notice board outside. The combination is the numbers circled in red ink.
Inside the safe you'll find a Hunting Pistol, ammunition, a medical kit, and some supplements.
