Read about how not to fail your research at the Cambridge Polymer Laboratory. Complete this Fallout 4 mission as efficiently as possible and get your well-deserved reward.

Fallout 4: Cambridge Polymer Laboratory quest

Fallout 4 quests sometimes include the most diverse tasks. Maybe that's why this game attracts the attention of lovers of various types of entertainment. Those who like to shoot enjoy fighting powerful and heavily armed opponents. Those who like to solve riddles and find secrets wander for a long time through the farthest corners of locations until they figure out all the features and crack all the secret places. The Fallout 4 Cambridge Polymer Laboratory mission takes place in a limited space, but nevertheless includes combat and many puzzles during the passage.

The quest poses certain difficulties, and not everyone manages to complete it the first time. Some players are complaining that the Cambridge Polymer Laboratory quest in Fallout 4 is not completed.

Chamber of Secrets

The mission begins by entering a laboratory where the protagonist is greeted by a robot named Polly. He conducts an introductory briefing and offers to work in the organization as a laboratory assistant. The conversation and slide show about the history of the laboratory take place against the backdrop of the devastation reigning in it. In total, the quest gives out two main tasks. You need to find a way out of the laboratory, since when you get there, the entrance is blocked due to radiation, and conduct an experiment using two reagents and an isotope.

In the Fallout 4 Cambridge Polymer mission, the secret room is located on the second floor of the laboratory. When you get to it, you will have to fight a little with ghouls, of which there are too many in the laboratory. The door of the room is blocked, and if the main character is not leveled up in the Hacker skill, he will have to get into it through an inconspicuous rise near the wall leading to the ventilation system. After going through several turns, you need to find a crack in the floor through which you can get into the room. Here you need to take a sample for research, unlock the door at the terminal and go outside, completing the first task. When leaving the room, beware of the electronic trap and wall-mounted machine gun turrets.

Conducting research

Traveling through the laboratory premises, we find three more unidentified samples. The U288 isotope is in a room with a glowing ghoul on one of the shelves. After collection we head to the test bench. We insert the samples one by one into the racks and enter the command to determine their composition on the terminal. The player's task is to find lithium hydride and gold. After determination, we insert lithium hydride into the left rack, and gold into the right one. We insert the isotope into the rack on the right side of the terminal and launch the production program on the terminal. We wait a little, and at the exit window we get piezonuclear power armor. This is how you can complete your research in the Cambridge Polymer Laboratory in Fallout 4.

The quest itself can be completed in different ways. If you kill the Director, an angry Polly will appear, and after his destruction, the passage of the Cambridge Polymer Laboratory Fallout 4 is marked completed. In this case, the experiment may not be carried out at all. But it’s still better to complete all the tasks, find the isotope and reagents, and make armor. Otherwise, the Fallout 4 Cambridge Polymer research will fail.

The correct ending to the quest will be a meeting with the robot Polly at the exit from the rehabilitation room. After talking with him, the doors will be unlocked and all tasks will be marked completed. This option for passing the Cambridge Polymer Laboratory in the game Fallout 4 will be optimal.

The Cambridge Polymer laboratories are located in the Boston-Cambridge area, and the story quest from the Underground “Underground and Undercover” or simply wandering aimlessly around the Commonwealth can lead you here. When you enter Cambridge Polymer, you will be greeted by the robot Molly and asked to interview for an employee of the company. You can refuse.

Charisma

You can try to convince her that they can’t do without you (persuasive level - easy). This way you can avoid a bunch of unnecessary questions.

Molly will show you the way to the laboratory

Complete the research

The essence of the quest is that you will not be allowed to leave the Cambridge Polymer laboratories until the polymer coating research is completed, but you can try to find another exit from the laboratory, which is described below.

The quest will begin when Molly takes you to the recovery room and locks you inside, there is no turning back, so go forward. Go through the crack in the wall of the rehabilitation room and from now on beware of wild ghouls.

In the first room - the laboratory, you will find a research terminal with two compartments for reagents and one for a radioactive isotope. You need to find the correct reagents (which you can learn about from the nearby terminal) and isotope to complete the research and create a unique piece of power armor. Unidentified samples are scattered throughout the laboratory. Once you find the samples, you will need to scan them for the terminal to detect the reagent.

Let's go looking for samples. You will find the first unidentified sample 11317 right next to the research terminal.

Go up to the second floor first to ensure a more optimal path. In the corner on one of the desks you will find a working terminal (level - easy), with which you can deactivate the lock on the safe (level - difficult) standing next to it.

On the second floor there are two laboratories C3 and C1. Go first to laboratory C1. There, in a small room with a chemical laboratory, you will find some medicines on the shelves, and on one of the desks there is an unidentified sample 49.

Climb the rise in the ceiling and follow the ventilation pipe to the very end and jump down the hole. This will take you inside Laboratory C3. Of course, you can enter through the main door, but then you will have to hack the door control terminal (the level is difficult) and try not to fall into the traps behind the opened door. In laboratory C3 near the Bergman terminal you will find an unidentified sample 611. By the way, this particular terminal is necessary for the Underground quest “Underground and Undercover”.

Also on one of the pedestals you will find a holotape “Password for the storage of radioactive materials”, which is needed for the isotope storage terminal located on the first floor in laboratory C5.

Find another exit from the laboratory (optional)

There is another way to complete the quest and exit the Cambridge Polymer laboratories. In the Bergman terminal in laboratory C3, select the line “Complex security system”, and then “Emergency replacement - penetration into the complex”. This will reset the isolation mode, but now you will have to be on your guard, as this will activate the turrets and the Molly robot to guard the Cambridge Polymer. After killing Molly, take the key to the director's office from her.

Let's continue the search for samples and go down to the first floor. In the small room to the left of Laboratory C4 you will find an unidentified sample 3111, as well as some medical supplies and a radiation protective suit that you may need in the isotope storage facility.

Go to laboratory C4 and take the unidentified sample 413 standing near the window. Then go through the hole in the wall in this laboratory to the next one - C5. On the cabinet opposite the wall terminal is the last sample 65.

Hack the wall terminal (level - easy), which will open the door to the isotope storage. The terminal can also be accessed using the password found in the C3 laboratory (read above). The entrance to the vault is located next to laboratory C2. There, on a shelf on the far wall, the U-238 isotope needed for research is stored. But before you approach him, you will have to deal with the glowing ghoul. Be careful, as he has the power to revive ghouls you have already killed.

Return to the terminal to conduct research in laboratory C2. And scan the samples one by one, after inserting two into the reagent compartments.

• Unidentified Sample 11317 - Hydrochloric Acid;
• Unidentified Sample 3111 - Lithium Hydride;
• Unidentified Sample 413 - Gallium;
• Unidentified Sample 65 - Tungsten;
• Unidentified Sample 49 - Cobalt;
• Unidentified Sample 611 - Gold.

We load lithium hydride and gold into the reagent compartments, and U-238 into the isotope compartment, and then select the line “Run loaded production program” on the terminal. After production is completed, pick up the unique item from the pick-up window.

Return to Molly and report on completion of the research. She will release you and ask you to follow her to the director's office.

Follow Molly and talk to the director

Exit the laboratory premises and go up to the second floor, passing through the kitchen and grab Yader-Cola in the refrigerator. Then the following will happen, either Molly will open the door to the director's office and the ghoul director will kill her, or you will kill the ghoul and Molly will attack you. Either way, finish them off. If you have already killed Molly earlier, then you probably took the key to the director’s office from her, if not, then go back for it, since the level of lockpicking is very difficult. Inside, on one of the display cases, you will find a nuclear unit for power armor.

Clue

Another number awaits you on the director's desk. "Massachusetts Surgical Journal" issue 6. It will unlock a new perk or enhance an existing one, and you will deal 2% more damage to limbs. The entire list of magazine perks and their actions can be viewed.

In the office, also located on the second floor, there is a box of ammunition on one of the desks (lock level is light).

The quest is completed, and you have a new unique item.
