The multi-layered wall system at the front slows down ground troops, giving your Inferno Tower and Giant Cannon more time to rain destruction. Attackers must break through multiple compartments before even reaching the core defenses.
The Inferno Tower and Giant Cannon form a deadly combination, melting through tanks and swarms alike. Their positioning makes it difficult for attackers to handle them without suffering heavy losses.
By placing air defenses forward and wide, you discourage aerial assaults early on. Any flying troops risk exposure to the full brunt of your throwers and Teslas. This forces attackers to deal with your ground defenses while slowly chipping away at the air threats.
