Firecrackers are the Builder Base version of Air Defense. Like the Air Defense, they attack flying units; however, they are slightly less powerful while also being slightly smaller covering a 2x2 space.
Firecrackers can only target and shoot one air troop at a time. However, it attacks 3 times every time it fires.
They cannot harm ground-based units, or interfere with them in any way other than potentially distracting them from attacking a more valuable target (e.g. the Builder Hall).
The Firecrackers is unlocked at Builder Hall Level 3.

At level 1, the Firecrackers appears to be a wooden box with ropes with fireworks pointing out.
At level 2, the box is reinforced with steel on all of the edges.
At level 3, the box is moved on top of a base composed of five wooden planks resting on four stone blocks.
At level 4, the four stone blocks in the corners are replaced by a solid stone base reinforced with steel.
At level 5, the box and the planks are replaced by a square "fence" of wooden planks embedded into the base.
At level 6, additional steel reinforcements appear on the corner edges as well as the top of the wooden planks.
At level 7, it develops a small stone platform on the bottom which wraps around the box.
At level 8, gold plating is added to all four corners and the fireworks develop a black and yellow striped pattern.
