Quick Answer: Sarah Watson, Matthew Clark, and George McEwan are the three blood bags needed for Transfusion Machine in Silent Hill Townfall. Place the bags in the correct wall stations before activating the transfusion mechanism. The circular dial puzzle requires blood paths to T.F., H.M., and S.W. Once all three paths reach the center, activate ORDELL to open the passage.
The Blood Transfusion Machine puzzle appears in the Otherworld Medical Center section of Silent Hill: Townfall. It combines two connected puzzles: first, you must position three patient blood bags correctly, then you must manipulate a series of rotating rings to route compatible blood into the central Ordell container.
If you’re stuck at the metal doors and aren’t sure which bags go where or how the circular mechanism is supposed to look, the solution below takes you through the entire sequence.
| Puzzle section | What you need to do | Solution |
|---|---|---|
| Blood bag placement | Insert three patient blood bags | Sarah Watson, Matthew Clark, George McEwan |
| Left wall | Place the first two bags | Sarah Watson, then Matthew Clark |
| Right wall | Place the remaining bag | George McEwan |
| Transfusion switch | Activate the machine | Switch beside the double doors |
| Circular dial | Route compatible blood to the center | T.F., H.M., S.W. |
| Final interaction | Confirm the solution | Press/interact with ORDELL |
The important detail is that the first part and the circular dial are related but use different information. The blood bags open access to the next mechanism, while the final dial requires you to identify the compatible blood sources and connect their paths.
How to place the Blood Transfusion Machine bags
Before you can solve the circular dial, you need to correctly install the three blood bags. The required bags are Sarah Watson, Matthew Clark, and George McEwan. Current walkthrough information confirms that these are placed across the central transfusion stations.
Step 1
Go to the transfusion stations along the wall and find the first station on the left.
Insert Sarah Watson’s Blood Bag into this position.
Sarah Watson’s blood type is A+, which becomes important again when you reach the circular blood-routing mechanism.
Step 2
Move to the second station on the left.
Place Matthew Clark’s Blood Bag there.
Be careful not to confuse this with Sarah Watson’s station. The two bags are positioned next to each other on the left side of the room.
Step 3
Move to the first station on the right.
Place George McEwan’s Blood Bag into this slot.
George’s blood bag is the only one of these three that belongs on the right side of the central machine.
The completed arrangement is therefore:
| Station | Blood bag |
|---|---|
| Left, first | Sarah Watson |
| Left, second | Matthew Clark |
| Right, first | George McEwan |
Different walkthroughs describe the positions using slightly different numbering conventions, but they agree on the physical arrangement: Sarah on the first left position, Matthew on the next left position, and George on the right-side position.
How to activate the transfusion and open the vault
Step 4
Once all three blood bags are installed, return to the area beside the large metal double doors.
Look for the transfusion/control switch next to the doors.
Interact with it to start the blood transfer.
Step 5
The machine will transfer the blood and unlock the route forward. Once the mechanism has completed its sequence, proceed through the newly accessible area toward the next puzzle.
How to solve the circular blood dial
The next mechanism is the more complicated part of the puzzle. It consists of several concentric rotating rings with blood pathways running through them.
Instead, you need to create continuous paths for the compatible blood sources that the puzzle identifies. The required initials are:
| Initials | Patient | Blood type |
|---|---|---|
| H.M. | Hannah McGregor | O− |
| T.F. | Thomas Fergusson | O+ |
| S.W. | Sarah Watson | A+ |
These are the three sources that need to be connected to the central Ordell container.
Connect H.M. + T.F. + S.W. to the center.
You do not need to route every patient into the central container. The puzzle specifically requires these three compatible blood sources.
The blood types involved are H.M. = O−, T.F. = O+, and S.W. = A+. The other patients shown around the mechanism are not part of the final required connection.
What happens after the transfusion puzzle
Once the central mechanism has been activated, the passage opens and you can continue through the Medical Center. The blood puzzle forms part of the progression toward the end of this section, with a later locked door requiring the Room 204 Key.
The puzzle can feel confusing because the game presents a large number of patient initials and blood types, but the important distinction is that you are filtering the available patients down to the compatible blood needed by Ordell. Once you understand that, the circular mechanism becomes much easier to read.
