This game really needs some kind of aim - it's just a bit endless at the moment!!
Also... they all seem to be men... no wonder this takes so much manual intervention!!
I don't get it... first time I played this game I just chose random stuff and got a character that dealt about 3 damage and the fights weren't too easy. This time however, I chose all the first options to make a solider... who deals about 45 damage each time with a 95% hit rate... I haven't had a fight take more than 2 hits yet! I hoping it gets a bit more difficult very soon!!
To those struggling and asking for advice...
To complete every level money is the key, so keep building salvage yards and sending 5 men when needed. If you are getting hammered, build an extra trailer and send more men.
Don't bother building the 'still', just build farm, garage then the chapel - once you can make a preacher you have pretty much won the level.
Oh and the harvester is funnier than the airstrike, so always use that!
