Now talking about the gameplay, as the players explore the north side of the Bailey Family Cabin, they will come across the Mysterious Caves. Inside that, they will find a door with a keypad punched beside it. To enter that door, the players need the code. So the players are searching for a way through it, and hopefully, that’s why you are here. Today we will discuss how to find the mysterious cave code and enter Vault 79. So let’s get started with our guide.

What is the Mysterious Cave Code?

Unfortunately, there is no quick answer to this question. This is so because it is random to each player, so it’s unique in that matter. Thus players need to obtain the code themselves. To do this, they have to collect six mysterious map fragments from different locations, and then they need to place them on a Board. That Board is found in the Grafton Pawn Shop. Here you will find six spots for the six mysterious map fragments in Fallout 76. We will discuss the six locations below.

  1. Morgantown High School: Next to the broken terminal and on the second floor
  2. Red Rocket Mega Stop: In the station to the east on a counter
  3. Haven Church: On a hallway counter
  4. The General’s Steakhouse: On a south-facing bar
  5. Uncanny Caverns: On the Welcome building counter
  6. Mothman House: On the front desk

These are the items or map fragments that you have to collect. Follow the next section for more information.

After collecting the special map fragments, you then need to head back to Grafton Pawn Shop. And visit the apartments that are located above.
