High level room suggestions akin to the cost of the Nuka-Cola plant, maybe more.

1. Security Office - Assign dwellers to patrol the vault for on demand response to rad roaches, and raiders. Upgrade to increase number of floors traveled. Effectiveness of security dependent on skill, gear, etc.


2. Logistics Office - Assign dwellers to automatically collect vault resources. Upgrade to increase resource types collectible, lvl 1 - power, lvl 2 - water, lvl 3 - food, etc. Frequency of collection depended on dweller skill levels.

Those two rooms I think would be great additions to the game and very well received by players, adding a level of much needed functions along with them.
