Shooting Box

Shooting Box is the fourth Defense in ScrapTD and costs 200 bricks to unlock.

Strategical use
This defense has been buffed many times, now a single one can take out Banana Hole and Billboard easily. After placing Gatling Guns to defend Banana Hole, placing one Shooting Box is recommended if the opponent sends multiple Billboards, otherwise the Billboards will get to the end, eventually tanking for Banana Holes, which can do massive damage to the player. It does some damage against Coal, but not a lot.

Overall use
Shooting Box is not that bad of a defense, does better overall against ground barrels compared to Airstrike. However it falls off once It's Alive, Danger Zone and above gets sent out, and it doesn't target Air barrels which makes sense since ground-targeting defences don't target them anyway.

Double Pain will be much better overall because you'll only get 1-2 SBs for ground barrels before you get rushed by Lurids or It's Alives in general, so it does quickly fall off once you reach the midgame.

Trivia

 * It received a name in update 0.4 by the suggestion "Blue Shooting Box" from elmenda452 also known as The Staryard, in August 2018.
