Besides the +xx% dmg that don't work, It's like metroid on steroid, I like it !
And you should put a warning sign before the giant-yellow-glowing-lazershooting-butterfly with something like "beware, over 9000 billions hp !"
The easiest way to get the medium (and the hard too) badge :
-Make a red turret
-Max damage (and upgrade 4 times rate and range...)
-Place 2 blue turret near the red, and max damage ONLY.
Once it done, a nuke (every 7 seconds) with 60 millions damages is shot.
-Make another nuke combo
-Place 2 yellow turret (tazer) near the road and max it (rate+damage)
-Make 5/6 nuke combo
Cover the map with BigDamage turret (combo benefits for it...)
In medium >>>> 4500 kills EASY (but do not forget to add....more nuke x) )
In extreme >>> 1600 easy =)
