For the blue tint, go to data, actors tab, and find the firebat's flame. When you find it go to the events for that actor and create a new event for Actor Creation. Then under actions go to Set Tint Color annd make it blue with a little bit of HDR.
Also you can make a little trigger that will spawn those zombies for you. Just do Events > Any Unit Dies... Condition > unit type of unit = Builger... Actions > Create unit at position of triggering unit

Good luck!
