Have them on the bottom of the vault to ignore all of the incidents happening there.Ī variant of the above, so that the events happening in each room does not propagate. Storage rooms, living quarters and Science/Medlabs are almost always empty. You could remove the learning rooms or have half of them depending on how many children you plan to have at any given time. Use the empty space here to build more power rooms as needed. The following design is the most effective. This means all rooms you do not use activily, group them together and separate them from activly used rooms. Molerats only spawn in rooms connected to dirt, elevator block spawning chances.If all rooms have been effected once, incident will end.Incident spread to nearby rooms if unchecked.The best defense is to guide the enemy through the rooms containing the dwellers with the highest STR and END which means your power rooms have to be the first in line and on the top floors. using this default elevator placement allows building 3 rooms to the left of.

On new floor, go left, then right if possible the default layout is 3 levels of elevators immediately in front of the vault door.If no elevator is at the end, move back until one is found.

Move through all rooms on one floor to the end.
