I did all the challenges, the last one was only hard because energy gets REALLY scarce. Disable the plant, build three windfarms, and defend the hell out of the base. After that night, branch out and go for metal and oil Defend the mines with one flame turret, defend the derrick/well with two normal turrets. Build two farms and protect those as well.
Best of luck, may the wind be at your side.
Only time I died was on level two, and that was because my computer lagged and raped me over on the boss fight. Guys, it isn't too hard. I suck at these types of games.
At first we were kicking ass, winning two to one, two minutes later they all died and I was screaming "OH SHIT OH SHIT OH SHIT!" never underestimate destroyers...
How is it a rip off of COD? The concept has been used infinitely, the only resemblance is the weapon choice (Even then it is slight). Probably one of the better flash shooters.
