Prison loot route: K9 cores, armory key and security cells

Four cores lead to the armory route; South Wing controls open an optional security-cell detour.

In short

Collect four K9 Battery Cores in the Citadel East Wing to reach the Main Control Room key, then collect the Legendary South Block Armory key from the control-room counter. The optional South Wing loop leads to a Secondary Control Room key, camera gates and a selectable loot cell. These pickups are shown in one edited run; availability and rewards are not guaranteed.

  • Four K9 cores at the East Wing terminal
  • Three separate key pickups in the recorded route
  • South Wing exterior access is a separate key

Approach the Citadel prepared

The 14th Political Prison contains the Citadel, a Critical-threat area. Bring armor, healing and ammunition. The route includes robot dogs, armed guards and radiation; it can become dangerous even before the armory.

The recorded approach selects Operation Iron Citadel for a closer starting point, then drives to Prison instead of the Air Base objective. This does not establish a mission requirement or fixed spawn. Approach the rear of the prison building, take the zipline, enter the door and descend to the East Wing dog area.

Four cores to the Main Control Room

Defeat the robot dogs and take K9 Battery Cores before they explode. Put four into the four-slot K9 Core Terminal. In the opened room, take The Citadel Main Control Room key from the desk beside the monitor and military case. Its full card is Uncommon; the differently worded Executioner notification is an uncertain alias, not another key.

Collect and use the Legendary armory key

Cross to the officers-only door and unlock the main control room. The South Block Armory key lies on the long counter beside radio equipment and telephones. Its full card reads Legendary. Leave by the front, pass the ammunition supply, enter the nearby window and unlock the inner armory door.

Search the weapon and equipment containers. A recipe is reported in this run, while the weapons are described as disappointing. Neither Legendary weapons nor a specific recipe or Weapon Manual are guaranteed. All three key cards display value 100; that is not a shop price.

Optional South Wing controls

Use The Citadel South Wing key at the exterior door. Prison guard drops are reported, without a measured rate. Inside, operate the lever and cell-control button, then take The Citadel Secondary Control Room key from the opened side room, beside two monitors. It is Uncommon; the creator already carried another copy.

A longer notes-and-keypad alternative is described for reaching the controls. The visible note contains 53 and another fragment is mentioned across the cells. The complete solution is not demonstrated: 53 is not a full or universal code, and the interior keypad must not be confused with exterior keyed access.

Cameras, fences and one loot cell

Return toward the central Citadel and climb to the landing described as labelled floor 2. Use the secondary key and security station. Switch camera views to operate two fences; LT selects the previous camera on the recorded controller, but bindings may differ. Use the existing map reference as an approximate area, not an exact door pin.

Leave the station, climb one more level, then cross to the loot cells. This corrects the earlier instruction to cross immediately. The creator says only one cell can be unlocked: inspect containers before choosing. Two large lockers are his preference, not a measured better-drop chance. Radiation affects this run; reassess protection and the exit before staying.

Extract without promising a fixed return

Use an available vehicle and an extraction point. Nearby cars are described as usual and a helicopter as occasional, not guaranteed. The narration reports Nylon Cloth, a recipe and three extracted keys; the reviewed helicopter footage does not show a results list proving three retained keys. Key uses and stash persistence remain unknown.

The 8:12 video contains cuts, so it is not an eight-minute farm benchmark. This detour does not complete Iron Citadel, establish cash per hour or guarantee unopened rooms. Compare other key routes in the Key Finder if the Prison is already looted.

Quick questions

Is the Legendary Prison key guaranteed every game?

The creator says it appears every game, but one edited run only establishes an observed pickup. Availability, key use counts and extraction persistence remain unverified.

Is 53 the complete South Wing keypad code?

No. The visible note contains 53, and another fragment is mentioned across the cells. The full code-entry solution and a universal code are not established.
