hard badge just..isnt hard, use the bad pipe level, place 2 blue turrets next to it, buy damage untill it costs 1100 to next, then buy rate untill 450 to next. *stay of range* Then, max damage, when that's done, place a red turret close to them, and max out *damage* and *range* It will ocassionally shoot a nuke, now, move them by using *m* untill the blue turrets can't hit the path. Spam in 20 waves, and buy a second nuke. Then, spam in groups of 10-20 waves and buy *;arge damage up* and place them so that they boost one of the 2 nukes. Do it untill you get 1500 kills. Easy enough.
Xzer, I´ve been improving my scores recently, and I have one question...how did you jump all the way to the top on baby steps in easy? I just can't pull it off in under 6 secs, and it ruins my score :(
At last :D I finished a level, i call it..."So close yet so far..." XD

Good luck :)
havent gotten the badge yet, but i think yur best shot is at the level with the pipes (and the floor crack at the left), get on the highest platform and dont come off again, youll probabbly make it. (though the little beans might get you)
4/5 the blood health is WAY WAY WAY too disruptive, 9/10 times i die because i cant see where im shooting, simple as that, make it more subtle or remove it.
