Actually, I take that back. Sniper shot and death ray is very useful vs a few enemies with very high hp. Especially those forest trolls, they don't get the chance to regenerate hp.
Tesla towers look a bit overpowered. Fully upgraded tesla deals tons of damage, on later levels I am able to pwn everything using only tesla and paladins. There is no need for archers or mages.
Very nice game, thumbs up!
Looks like some upgrades aren't working in the challenges - although I have all the Magic upgrades, the towers cost 100, instead of 90.

Go with the policeman and the paramedic, take the motorcycle, take the crowbar, let the looter go, barricade the house, kick the attacker off your wife, cut her fingers.
