The backyard bunker is a small bunker containing bunkbeds, a restroom, and a common area. It is also the source of the Separated family radio signal. It contains a terminal that contains various logs and also controls the wall safe locking mechanism, which would otherwise have an Expert lock.
- Nuka-Cola Quantum on the table in a bucket.
- David's holotape which can be ejected from the terminal.
- A hazmat suit on one of the shelves.
- A Vault-Tec lunchbox on the kitchen counter.
Viewing the logs on the terminal in the bunker will add the Irish Pride Industries shipyard icon, as well as the Mass Bay Medical Center icon to the Sole Survivor's map if not yet discovered. This is due to the location of the missing mother of the bunker's original inhabitants.
The backyard bunker appears only in Fallout 4.
