There are quite alot of glitches in the game, For example, after moving around my galaxy turret from one spot to the next, damage went up from 72 to 154, and the rate of fire from 0.6 to 0.3. This makes it almost instakill most easy bosses.
For the How? badge (4 nice tries) you need to do this at the beginning of the game, right at your first match. During that match grab just enough coins to unlock the vira healer and aegis barrier, along with the 500 gp upgrade for two extra units. Build only aegis barriers, and 10 healers surrounding your base. Place at least 5 aegis barriers at the far top of the map. enemies should attack these. When the boss arrives build only 4 core blasters, and destroy them each and every time they lose even 2 lives, so that they count as a unit loss. When the boss goes into rage keep replacing the core blasters with new ones as they die. I passed the level with 45 units lost, 4k gold picked up, and a boss time of 130 seconds. I killed 15 units, and got the nice try badge
Fml... my titan barrier got the first level X upgrade after 20 hours of gameplay.... useless, an update should be made that barriers cannot get Level X, because all it does is add 120 Hp, which is an utter waste of 20 hours of gameplay
Easy way to make money, do the 450 vault challenge and always choose the bottom one. On my game this was the vault with diamonds 2/3 times. Enjoy and +
The bosses, once you get passed the first three waves, all you need to do is to continually press (Hold down) the space bar and have the Knight as your only unit. Then press "S" also continually and have walls and catapult upgraded to the max. This will kill all bosses without any effort.
+ to keep alive
For the 25000 budget try using omega sledge with longest ramp, then buy a glider. The speed from going down gives u 13k points, glide out the rest, i got close to 20k that way :)
