i got up to the last level in the game (havent played it yet) and i did it using damage-upgraded vulcans, range-upgraded frost towers, speed-upgraded dissipater's and damage-upgraded skybeams. the trick to beating ANY defense game is to make the enemies run around your cannons so they have 2 chances to shoot them, which almost doubles your damage output.
i preferred the vulcans because they attack super fast, low cost and can end with very high damage per shot. since frost stacks per cannon, its a ridiculous amount of damage.
the problem i have with this game is that both laser and skybeam cannons miss, air flies out from random locations and the maps are a little small.
