vector td on out of ba page (in Off-topic)

can anyone beat any of the hard maps?
i cant get past level 30 on each of them

I've gotten up to lvl 40 on the frog, and beaten it on no left turns. The key is a strong early game. Liquid assets and interest worked for me. My first bonus was interest and then I saved my next 3 bonuses until later. I ran a mass smart rockets with mass slows strat. The slows worked so that when I ran up against green and yellow vectors, my rockets had enough time to do enough damage. I found the purple twrs to be mostly useless and same with the upper greens (green 3 is bad unless fully upgraded and masses which is expensive as hell) Also spending money at the right time is key to maximize your interest. GL!

ya i ran mass slows and smart rockets on all the ones ive beaten, but i figured it would take something else to beat the hard ones. how did u start frog? red laser for 2 rounds right?
