you should add two things: 1. is a building that covers all the levels under it (like the normal collector, but more expensive, and covers EVERYTHING under) 2. an award for "green map", when the player covered in green more then 99% of the map.
i mean ... sc**w the score, everyone just wants to OWN those emitters.
If ever there's a v3.0, the buildings should be completely demolishable (i just hate missing appartments, and having 7 labs), also you definitely need to add a smart training system (assigning people to a school for 2 days is just silly). Also, people that don't do anything should automatically be assigned to the defense incase of a zombie attack. and last, but MOST important, people should be allowed to take items from the warehouse, the current items assignment system is so hard to use (TOO MUCH crolling up and down) ... OVERALL the game is awesome, and i give it a 5/5
