I have 3 stars on all missions up to level 11, cant even get 1 star on level 12. I have tried different upgrades with no success, the last wave (10th) is impossible.
Try not to spend a lot of money, but to save. Approaching the 10 wave, you should have about $ 10,000 (maybe a little less). When will be the boss, he'll tear down your towers and you will need to buy them quickly
