I finished with Punisher, Bad Boy and Beast. Bad boy was not fully upgraded. Don't really think having trucks are all that important. I think mostly have 2 miniguns for air crowds and 1 railgun for grown crowds should be enough. The UAV helps but doesn't need to be fully upgraded (about 3 should be enough to last you the whole game).
It would be cool if Epic War 6 had a map and you can be attacked as well as attack. Also maybe put the castle system back in, but to make it more realistic, make that castle a supply tent when you attack someone. And make individual upgrades for both castle and tent. o.o
