Not that great.
2/5 because it didn't suck, but it really doesn't impress as much as any of the other major flash games out there.
WAY TOO EASY
ALL I HAVE TO DO IS SPAM
Easy & Repetitive, but good
Simple, easy win:
Buy some mines
Buy one to three death bringer
Buy all the rest of flying horrors
Use mines to kill anti air, then use the flying horrors, then the death bringer(s)
very easy, went like that from 12 to 20
A little repetitive, but fun nonetheless
I'm giving this a nine because it does get boring and a bit repetitive after you get to the half-way point. Some additional abilities for the alien dropship thing would be nice.
No doubt most will have trouble once they get to level 12 where air units are virtually useless. My tactic was to use a combination of fully upgraded Painful Rollers and Mines to clear all ground troops, and a couple of Spined Crawlers to clean up what's left. Yes, this combination cleans up everything from level 12 to 20.
Basically, you use just enough mines to clean up the tanks (especially the rocket tanks from lvl 14), also make sure to use the splash damage to the fullest. Some patience and timing is required here. Then, find the center of the map and drop all the rollers. Immediately after, drop your spiners. And that's it, fast forward, make yourself a sammich or scout around for shockwaves.
Great. gave a nine because of many movement glitches.
Strategy for ultra winning above lvl 11: upgrade all monsters to max everything.
Use maxxed out 2-3 slicer guys with the scythe arms and use the rest of the dna for the fast and first alien. maxxed out, they need to be all from one side, all falling in front of the pack. save like 8. then use behind the mob . make mob then slicers then reinforcements.
They will NOT get rid of all enemies. just most of them.
Use he bonuses and precise shockwaves to destroy the rest of the buildings after the slicers. I am at lvl 17 with this technique.
