How to Obtain the Serum in Resident Evil 7

As you progress through Resident Evil 7, the serum plays a pivotal role in curing the mysterious affliction that affects the characters involved. The primary components required to synthesize the serum are the D-Series Arm and the D-Series Head. Let's explore where and how to find these crucial elements.

D-Series Arm in RE7

To acquire the D-Series Arm, you will initially find yourself in the Old House. After obtaining the Crow Key, return to the room where you previously acquired the crank. Use the Crow Key to unlock the door and proceed to your first confrontation with Marguerite, a significant boss in the game.

Once you've defeated her, enter the crow door, access the altar, and read the document titled Serum Documentation. Ascend the stairs to also collect Marguerite's Notebook. Next, head to the greenhouse for your second and final battle with Marguerite.

After conquering Marguerite once more, you can freely explore the Old House, as she will not reappear. Make your way to the cell by navigating through the children’s room and the contaminated area.

In the wall behind the bed, push the distinct section of the wall to reveal a passage. Inside, you’ll encounter a creature. After examining it, you will successfully acquire the D-Series Arm, which is the peripheral nerve you need!

D-Series Head in RE7

Next, we turn our attention to obtaining the D-Series Head. Begin in the main house after finding the two keycards that Lucas requests. The first step is to enter his "party" by going to the patio and placing the keycards into the illuminated door.

Upon entering the test area, watch the surprise that Lucas has prepared for you on the television. Follow the instructions he offers while navigating through various rooms, being careful to avoid traps and confrontations with molded enemies. When Lucas appears, make sure to use the final password and distance yourself to survive.

As you navigate through the barn, you'll face several molded enemies, including one particularly large foe. After this, collect the document titled Note on Charred Body to obtain a crucial password for your next step.

Once you complete the "Happy Birthday" puzzle, Lucas will throw a bomb at you. Position the bomb near the wall segment that has a patch next to the barrel so that it reveals a hidden passage upon exploding.

Upon entering this passage, you'll find a safe room where you can acquire both a map of the test area and the D-Series Head, which is the cranial nerve you need!

How to Create the Serum

With both the D-Series Arm and Head in your possession, head to the dock to release Zoe and Mia. Present them with the D-Series Arm and D-Series Head, and you will officially have the serum in Resident Evil 7!

We hope this guide serves as a valuable resource in your quest to obtain the serum in Resident Evil 7. Happy gaming!
