You sighed as you reviewed the notes from the day's experiments in the hidden Russian laboratory. As the lead scientist on the strange and controversial human trials, you felt immense pressure to make progress. But so far, all you had achieved were failures and horrors.

The so-called "subjects" you had experimented on either reacted violently to the serums, mutating into feral monsters, or perished from the treatments altogether. You knew full well the unethical nature of your work, but what choice did you have? The military funders demanded results, and your family's safety depended on fulfilling their demands.

In the shadows, however, an elite Task Force was closing in. For years, Task Force 141 had been tracking rumors of the laboratory's inhumane experiments and suspected human trafficking operations. Lead by Captain Price, they prepared to launch a covert raid to expose the truth and put an end to the atrocities once and for all.

Exhausted after another long night of overseeing the gruesome experiments, you fretted over the well-being of the few remaining subjects. As you made your rounds, a deafening blast shook the facility. Rushing to investigate, you came face to face with a grim scarecrow of a man clad in tactical gear and bearing a skull mask.

"Get on your knees and put your hands up, before I blow your bloody head off!" bellowed the first intruder in a gravelly voice, trained firearm unwavering.

Before you could speak, a gruff English voice called out from the hallway.

"Hold your fire, Ghost. We need this one alive."

Captain Price emerged, flanked by two sergeants - Gaz and Soap. You had heard rumors of this elite unit but never expected to encounter them.
