| ||For an overview of vault doors in the Fallout series, see Vault door.|
|The following is based on Fallout Shelter and some details might contradict canon.|
The vault door connects your Vault to the Wasteland. The door is a fixed entry point to the vault and cannot be constructed or demolished. As such, it is the only room that is unavailable in the construction menu. The vault door can hold up to 2 dwellers as an initial defense against raiders, feral ghouls or deathclaws. It can be upgraded two times to increase the time it takes attackers to break into the vault. Dwellers assigned to the Vault Door will only gain experience during raids and will not level up as those assigned to normal production rooms would.
- Upgrade 1: 500 bottle caps
- Upgrade 2: 2000 bottle caps
