Airstrike

(Defense 3) is the third Defense in ScrapTD. It's the third pursachable in the game and costs 200 bricks to unlock.

Strategical use
Defense 3 is very strong and this one costs a lot. It takes some time until it's pursachable. It's the first that can attack flying barrels, perfect against Lurid Layered which costs 500000. It's suggested to buy the first three at the beginning.
