Strategy content gives players a reason to read, replay, and explore similar games.
Survival depends on "Choke-Point DPS." Place your strongest towers in the "Middle Columns." They have the widest firing angle (can shoot left and right). A pro strategy: "Freeze-Delay." Use "Ice Towers" (if available) to slow down the high-HP blocks, giving your DPS towers more time to chip away the numbers.
