Airstrike

Airstrike is the third Defense in ScrapTD and costs 200 bricks to unlock.

Strategical use
Airstrike is the weakest defense and costs a lot, 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 be able to defend it, but not this defense. It can help quite a bit to clear out Banana Hole, but usually you just skip this one and use Shooting Box instead.

Trivia

 * It got named by Schrottii in 0.4, inspired by the Airstrike article in the english wikipedia.
