For everyone wondering how to get more towers: Beat the challenges, they are all fairly simple early and unlock new towers and more of existing towers.
I'll try to get something like this done in the next update.
For now, please just start a new game to revisit the intro story mode.
Thanks for playing! glad you like it!
Archers, Archers, Archers... were archers meant to be this overpowered? Seems odd that your second unit is nigh unstoppable with its aura burst.
A few archers in your aura = you win 95% of the levels for free.
Kamikaze Badge: If anyone is having trouble with it, try and max your laser wingmen. When they are maxed just try and stay near the bottom of the screen. They alone will almost get you to 10,000,000 points with minimal dodging.
Just got ~27mil without much movement from the bottom of the screen.
