The higher the SPECIAL stat of a Dweller is, the longer it takes to train them to the next level. Multiple Dwellers training together in the same room decrease the training time for all Dwellers in the room. Rooms can be upgraded to increase their performance. Each room type save the elevator can be upgraded twice. Upgraded rooms produce more resources, increase storage capacity, train faster etc. Upgrading merged rooms is significantly cheaper in the long term.Three merged production rooms triple the output and provide an additional 4 resource units.Two merged production rooms double the output and provide an additional 2 resource units.Merged Rooms let you assign more Dwellers to the room (up to six), while also becoming more efficient, however, they consume more electricity and increase upgrade cost.Īdditionally Rooms can be merged by placing them next to each other, up to 3 Rooms of the same type and level can be merged into a larger version of the room.

Two merged rooms cost 25% less caps to upgrade as opposed to two single rooms. Fallout shelter 3 rooms together upgrade#.
