Upgrading the room seems to have no noticeable effect on a room's pool size. So the pool in a double room is twice the size of a single room, and a triple room thrice the size of a single. When a room is merged the pool size is increased to match the new room size. When the pool is full the room is ready for the player to harvest its resource, after which the pool is emptied and the dwellers need to fill it up again. Every second all working dwellers in the room add their relevant SPECIAL stat to that pool, increased by the vault's happiness bonus. Resource rooms operate with a hidden time pool (hereafter simply referred to as 'pool'). Depending on the luck of the workers, collecting the resource may also yield a sum of caps.

Once a room has produced a batch of its resource, it will not produce any more until one collects the resource. Although it is not visible in their SPECIAL stat bars, wearing outfits that raises traits beyond 10 increases production rates. Production times are also modified by the room's size, upgrade level, and the working dwellers' happiness. four dwellers with Strength 5 in a double-generator room are as productive as 2 dwellers with Strength 10 in the same room.

Production time is dependent on the assigned dwellers' total trait level for the room's required trait.

Production rooms periodically yield one resource, except for the Nuka-Cola bottler, which produces both food and water. For example, the first medbay costs 400 caps, the second costs 500 caps, and so on. The cost of each new room is dependent on the number of rooms of that type already in the vault. The game begins with a stimpak and RadAway capacity of 5. The only exceptions are the overseer's office, which enables one to send their dwellers on quests the vault door, which acts as a first line of defense from invasion and elevators, which allow dwellers to navigate between floors.Įmpty rooms are vulnerable to infestation if one cannot move dwellers into an empty room to eradicate the problem, the infestation will spread to adjacent rooms. Rooms in Fallout Shelter typically split into two categories: production and training. The vault can have a maximum of 200 dwellers living in it. Adding more than two elevators per floor will sacrifice space for other rooms. In addition all floors can hold up to two elevators. There are 25 floors all floors can hold eight rooms.
