The "Police Control" upgrade doesn't seem to prevent corrupt cops on survival mode. If you are going for the hard badge, don't waste your money on that.
@Daemonwolf You've reached the maximum output capacity of the city. The Deficit bar measures the "starvation" of the weapons/structures, not the completion/depletion ratio. It goes up every time you cant deliver enough packets to the structures. You can countermeasure that by spacing better the weapons on the front line but, nonetheless, it's still a major problem after 100 or 120 minutes.
to "beat" the survival mode, don't be to hungry. stay back where the creeper layer is shallower. create a line of mortars with a line of blasters behind them. the blasters will keep the creepers away from the mortars and the mortars will reach the more concentrated layers. don't send more than one drone to a single point; it's useless. move the city closer to the lines to speed the packets delivery. upgrade the reach when possible but not the fire rate. don't pack the lines too tightly or you will starve; the city has a limited output.
