Humanity has always feared the Cybermen. Cold, relentless, logical-they have upgraded across centuries in the name of survival. But now, something far more insidious has taken hold.

A new signal pulses across the stars, rewriting their purpose. Under the influence of BOSS, a corporate intelligence born of profit and ambition, the Cybermen are no longer content with simple conversion. They have discovered marketing. Worlds are not conquered by force, but persuaded by slogans. Colonists march willingly into the factories, chanting jingles that soothe their fears as their flesh becomes steel. Entire galaxies flicker with advertisements promising The Better Life.

When the Doctor intercepts the signal, he uncovers the terrifying truth: logic has been replaced with branding, and obedience has been packaged as the ultimate product. But even he is not immune-exposed to subliminal conversion, the Doctor feels his own mind bending toward the green spiral of profit and purity.

To stop BOSS and the Cybermen, the Doctor must weaponize language itself, turning paradox into rebellion. Yet every victory reveals a deeper threat: the Cyber-Empire has become a franchise, expanding across the stars.

And Earth may already be the heart of its market.
