Fallout Shelter is a game that was released in November of 2016. It is a post-apocalyptic shelter where the player can play as one of four characters. The game has been praised for its graphics and gameplay, but it has also been criticized for its lack of features. One of the main complaints about Fallout Shelter is that the player cannot upgrade the Vault Door. This means that the player cannot add new rooms or mods to the shelter, and they are also unable to use any other features to improve their experience. One possible solution to this problem would be to add an upgrade system for the Vault Door. This system would allow players to purchase new upgrades for their Vault Door, and they would be able to use these upgrades in order to improve their experience in Fallout Shelter. Another solution could be to add new rooms into the shelter, which would allow players more opportunities to explore and play with their characters. This would give players a more varied and interesting experience in Fallout Shelter, and it would make it easier for them to find what they are looking for when they are playing.
