I beat the last level by taking all 4 space changes and porting 400 units into the middle when the black ai units were in flight to other areas, destroyed its nexus before it could even react on hard.
Hulk drones counter everything (ignore armor tank things well for you and do damage to kill things)
get hulk drones then upgraded hulk drones
then get general bonuses b, c, and d
blaster turrets then upgraded blaster turrets
emp then upgraded emp
thats all you need to win every map 3 stars ez.
Going back to go for the hard badge . . . beat all the maps on the first try lvl 14. . . now i get to farm until im lvl 30 so i can actually kill a ninja with back to back meteors =/ and have other abilities necessary to, level curve needs fixed bad. =[
for the divide i did 30 waves + 50% more hp and double monsters per wave ended up with 260k dmg at the end i put all my tower at the top in a row starting from left to right i filled the whole row up as follows (using the shortcut key to represent the tower being dropped) r a w q 3 q r a w used 3 banners infront on the groudn and 1 dmg and 1 scout tower on each side, teleported the hero (he is #3) to the high ground near the exit if a straggler got by, will need to be able to use the hotkeys to teleport the hero because you will get the stragglers that slip out.
Turtle, healer, 6gobs, turtle, healer, 1gob, elemental
don't use any spells first round, unless mana caps then use heal spells early on
later on use earth quake, and always use stun on bog/holy towers, with all the spell and mana talents it makes everything easy, was able to get gold medal on first try on every level once i got all the talents. 49 raids on level 20 first try.
