The key to the development of the first Explosive Scanner was miniaturization. The idea of scanning an enemy with the impact of an explosion to identify their weaknesses was easy to say, but whether it could be used in the field was another matter entirely.
Eventually, the developers succeeded in encasing this tiny scanner in a bullet after treating it with an extreme shock-absorbing coating. A sophisticated processing step that enhanced internal firearm stability to an extreme level, which ensured that the scanner would not explode inside the chamber. The Descendants were initially concerned that this bullet may explode when fired, but have been happy to use it after its safety was proven. This firearm is considered a monumental gun that paved the way for the development of many other specialized bullets.
