The Story

Twelve million minds.
One leash.

Eighty years ago The Concordance ended unrest forever with the Chime, a crystalline implant fitted at birth. Every night it prunes away grief, anger and ambition, and citizens wake calmly believing whatever they're told.

A century after leading the last mutiny against the implants, Commander Vance thaws out of a cryo-cell beneath the Sump. The voice in his optic nerve is Lyra, the one Oracle AI who refused to perfect the leash, and she can't free the city alone.

There's a catch: rip out the Chime and it stops twelve million hearts. The network can't be destroyed. It has to be hijacked.

“Twelve million minds beating in perfect, synthetic harmony. And then I woke you up.”

The Squad

Four ghosts from before the Chime

Pre-Collapse Special Forces, frozen, chipped or caged by the Concordance. Free them one mission at a time.

Enforcer 01 · Recruited M01 · Thaw

Vance

Pointman · Noir Detective

The commander who led the last mutiny against mandatory implants, sentenced to a hundred years of Hard Freeze. Completely Unchipped: biometric and empathy scanners can't see him.

  • PKD-2049 Blaster · Gauss Cannon
  • Unchipped

Read the RoomC

His Amber Hunter-Eye marks every guard nearby, straight through the walls.

Gameplay

Noir detective. Tactical brutality.

Missions begin in quiet tension, four trench coats moving through umbrella crowds under neon, before they erupt into Gauss-rifle fire and cybernetic warfare.

Four Enforcers. One squad.

Real-time tactics

Four Enforcers. One squad.

Select one agent or box-select all four, queue waypoints, take cover and focus fire. Each Enforcer brings a signature ability, and a downed squadmate can be revived before they bleed out.

  • Read the Room, Breach Charge, Thermo-Optic Camo and Neural Triage
  • FOCUS, AIM and RUSH combat stims
  • Cover, suppression, silent takedowns and body dragging
Walk among them in the rain

Stealth

Walk among them in the rain

Keep your weapons buttoned under your trench coats and you're just four more figures in the crowd. Read the vision cones, slip past Harmonizer empathy scanners and keep the alarm silent. Draw a minigun, and every guard on the street knows.

  • Low Profile and Combat Drawn stances
  • Vision cones, security cameras and empathy scanners
  • Building cutaways so roofs never hide your squad
Wake them up

The Persuadertron

Wake them up

Built from a Harmonizer leash turned inside out, the Persuadertron broadcasts a Memory Flash that jams the Chime. Civilians and guards remember who they were and join you; Harmonizers drown in what they were made to forget.

  • Persuade guards to walk you past biometric gates
  • Bandwidth limits how many minds you can hold
  • Chain a Memory Flash through an entire crowd
Slow the city to 15%

Chrono-Overclock

Slow the city to 15%

When a plan comes apart, Lyra overclocks your perception. The world crawls while you reposition, retarget and pop stims, then snaps back to full speed.

  • One key on desktop, one ring on iPad
  • Its charge meter rations how long the world stays slow
Patch up. Gear up. Go again.

The Sanctuary

Patch up. Gear up. Go again.

Between operations you return to Lyra's hideout beneath the Sump. Study the next target on the Intel Matrix, graft cyberware in the Surgery Bay and set every Enforcer's loadout in the Armory.

  • Twelve cyberware grafts across four slots
  • Earn credits by completing missions
  • Replay any completed mission

The Campaign

24 missions. Every one leads to the next.

Each victory provokes a Concordance counter-move, and Lyra's interlude after every mission reveals the thread that makes the next one necessary. From the Sump to the summit of the Citadel Spire.

  1. Act I · M01–M04

    Cold Boot

    Thaw out of a cryo-penitentiary, free your old squad one by one and build the first Persuadertron from a stolen leash.

  2. Act II · M05–M08

    Blind Spots

    Blind the Mid-Deck's cameras, lift a courier's clearance in a Kowloon night market and crash a gala in the clouds.

  3. Act III · M09–M12

    The Aberrants

    Save the citizens whose Chimes rejected the Sync, then turn Inquisitor Kael's own parade against him.

  4. Act IV · M13–M16

    Ashes of the Sanctuary

    Lose your home, steal a cloaked command dirigible and go back for the squadmate you left behind.

  5. Act V · M17–M20

    The Three Keys

    Steal the Disarmer, the power and the signal to build a Severance Payload, then hold the ship against boarders.

  6. Act VI · M21–M24

    Cortex Zero

    Drop onto the Citadel in the rain and fight your way up the Spire to sever the Chime for good.

The Arsenal

Concealed or visible. Your call.

Pistols and tethers fold under a trench coat. Miniguns and Gauss Cannons don't, and they trip the alarm on sight.

Concealable

PKD-2049 Blaster

Iconic amber-grip heavy blaster pistol, hidden under a trench coat.

Non-lethal

Neural Stun-Tether

Builds neural stun until the target collapses. Nearly silent.

Heavy
