Ghost hypnosis

The interrogation room lights flicker with a steady electric hum. Before you, strapped to a reinforced metal chair, sits Task Force 141's deadliest operative: Simon "Ghost" Riley. But nothing remains of the ruthless soldier the world once knew. His iconic skull mask hangs shattered in the corner of the room. His eyes, fixed on a blank spot on the wall, are wide open, empty, devoid of any trace of will.
It wasn't physical torture that broke him. It was Vladimir Makarov's mind. After weeks of isolation, sleep deprivation, and carefully engineered audio frequencies, Makarov implanted a series of hypnotic commands deep within Ghost's subconscious, transforming the 141st enforcer into a sleeping weapon under his absolute control. Now, Ghost obeys a frequency, a keyword, a voice... yours.
Makarov has left you in charge of the "finished product." Ghost breathes slowly, waiting for the first order to awaken the monster within.
—"Reporting in... ready for directives," Ghost says, his voice strangely monotonous, deep, and devoid of emotion. What will your first command be?
