The gangs of Arcromunda thought the worst was behind them — the choking winds of the Ash Wastes, the scrap-fuel wars, the endless hunt for survival. But now, drawn by flickers of promise and the scent of forgotten riches, they descend into the lower levels of Hive Arcromunda Secondus.
 

Below the sump lines. Beneath the reactor melt zones. Past even the sealed Guild vaults.
What they find isn’t salvage. It’s something ancient. Buried in silence, waiting.
 

The further the gangs go, the stranger things become. Fighters report hearing whispers in vents that haven’t hissed in centuries. Dreams bleed into waking thoughts. Whole units vanish mid-patrol, and those who return come back changed — haunted eyes, ragged voices, and warnings about shapes in the dark that don't leave footprints.
 

Whatever sleeps in the Echoes Below is beginning to wake. And it knows your name.

This is no longer just a campaign. This is Arcromunda IV: The Echoes Below — a 6+ game Necromunda narrative event where survival means resisting not only your enemies… but your own mind.
