If you want thrills in tower defense games, then definitely try Merge Tower Defense. In this game, you do not just have to install turrets, you also have to merge them so that they become more powerful. And there is also a tycoon-style money system where you can earn money from zombies and build more turrets. Quite an addictive combo, isn’t it?
But yes, it can be a bit tough in the beginning. Less money, basic turrets, and zombies never stop. That’s why codes are quite useful. These codes give you free diamonds, with which you can get new weapons or upgrade them without extra grinding.
