Airstrike

(Defense 3) is the third Defense in ScrapTD and costs 200 bricks to unlock.

Strategical use
Defense 3 is very strong and costs a lot, and It takes some time until you can build it.. It's the first that can attack flying barrels, but isn't really strong against Lurid Layered. Double Pain will do best against it, neverthless it helps quite a bit to clear out Banana Hole and Billboard.
