X2, You can't get thru mission 3 without at least 2 DCA'* imo.
I never ever used DCA'* until mission 6. and DONT UPGRADE THOSE WEEK TOWERS (turrets) use them only to set up your maze.. Upgrade the Plasmas all the way. thats all I did until like mission 6 lvl 40 or so. I got up to lvl75 cant go anyfurther though.

Really? A fully upgraded Sniper Tower is slow to fire, but does 400 damage. It is also relatively cheap to fully upgrade. I use these in conjunction with fully upgraded plasma turrets and they seem to compliment each other pretty well.
However, the fact remains that you have progressed WAY further than I have in level 6
