In the dimly lit streets of a bustling metropolis, there was a legend whispered among arms dealers and mercenaries alike. It was about a weapon, not just any weapon, but a sleek and deadly MP5 SD known only as "Hot Coal".

Crafted by a clandestine group of weapon engineers with a penchant for the extraordinary, Hot Coal was no ordinary firearm. Its matte black body resembled the darkest coal, a fitting disguise for the inferno that lay within. But what truly set it apart was its fiery tip, a blazing ember of red that flickered like the glow of a coal set ablaze.
