Walkthrough
  1. 1
    Make your way to the nearest Hideout.

    Analyze William Marshal's Memoirs to unlock the Antidote formula. The required ingredients are William Marshal's Blood, King Arthur's blood, and a Dose of insulin.
Tips
  • If Dr. Swansea died, the health of the Pembroke Hospital district will drop from Sanitized to Critical.
  • If you have the Small Key from Dr. Swansea, use the lift in the hospital to go down to the area where you fought McCullum. This key unlocks a chest containing medical components and Swansea's Diary.
Walkthrough
  1. 1
    Return to Usher Talltree in Temple Church and give him his notebook.
  2. 2
    Examine the Origin of the Brotherhood document in your inventory and pay attention to the sketch in the top right of the page. This sketch corresponds to the pressure plates near Usher's base.
  3. 3
    Look for other documents penned by Usher that contain a doodle and a die-face to determine the order of the pressure plates. The documents hint at the order: The Crime of Lost Knowldge (fish), Laughing at the Guard (circle), The Myth of the Horned Vampire (square), Rare Species of Vampire (oval/circle), Origin of the Skals (fish), Blood as Addiction (diamond).
  4. 4
    Deduce your specific sequence of pressure plates based on the sketch in Origin of the Brotherhood and the hints from other documents. For example, a sequence might be: Top (fish), Left (circle), Bottom (square), Left (circle), Top (fish), Right (diamond). Your sequence will differ.
  5. 5
    Face the solid wall opposite the stairs and activate the plates in your deduced sequence.
  6. 6
    When the sequence is correct, a secret room will open.
  7. 7
    Examine the paper on the pedestal inside the secret room to obtain the Recollections of Paulus Aurelianus.
  8. 8
    Pick up the sword to obtain the True Dragonbane sword.
Tips
  • The True Dragonbane sword is the most damaging single-handed weapon.
  • The arrangement of shapes on the pressure plates is different for each playthrough.
Walkthrough
  1. 1
    Make your way from district to district, draining every citizen.
  2. 2
    Note the following citizens who drop unique weapons: Charles Albright (Charles' Truncheon), Louise Teasdale (Louise's Machete), Clarence Crossley (Clarence's Parabellum), Giselle Paxton (Giselle's Dagger), Ichabod Throgmorton (Ichabod's Stake), Rodney Grader (Rodney's Scythe), Archer Woodbead (Archer's Hatchet), Seymour Fishburn (Seymour's Bludgeon), Sabrina Cavendish (Sabrina's Dagger), Tom Watts (Tom's Revolver), Booth Digby (Booth's Axe), Edwina Cox (Edwina's Double-Barrelled), Newton Blight (Newton's Saber), Clay Cox (Clay's Hatchet).

    Gwyneth Branagan drops Gwyneth's Surgical Knife.
  5. 5
    Thoreau Strickland drops a key which opens a cabinet in the Doctors' office containing Thoreau's Surgical Knife.

  11. 11
    After draining all citizens, rest in a Hideout.
Tips
  • Embracing everyone in London will make the endgame significantly more difficult.
  • Acquiring the unique weapons will unlock three related trophies.
  • Fetching Samuel Connor's Mace from the Morgue Basement requires fighting many Priwen; use firearms and ranged attacks to avoid aggroing all enemies at once.
  • When you rest in a Hideout, the status of all districts will collapse, unlocking the Anarchy in the UK and London's burning trophies.
  • You will likely want to restore your backed-up save after completing this to continue your game normally.
Walkthrough
  1. 1
    Fight your way to Lady Ashbury's House.
  2. 2
    Head upstairs.
  3. 3
    Engage in a scene where you tell Elisabeth everything you know about the Skal epidemic, including that she is a carrier.
Tips
  • The Priwen guards encountered on the way to Lady Ashbury's House are in the mid 30s.
  • If you have a long Stamina bar, you can evade past guards and keep moving until they lose aggro.
  • A Chaplain and a Brawler with a Fire Executioner can make the fight difficult.
