While traveling around Boston, you may come across the Cambridge Polymer Laboratory building in Fallout 4, where a small side quest awaits you. Immediately as you enter the building, the robot secretary Molly will rush towards you, who will inquire whether you have come by chance to advertise a job. If you decide to cheat and answer that it is so, then the secretary will give you a task to determine your professional suitability. With the help of dialogue options and the possibility of persuasion, you can claim a better place.

Walkthrough

This will be followed by a short dive into the history of this place, after which you will suddenly be asked to complete a certain experiment. You will not have the choice to refuse, so you will have to follow the instructions. As soon as the door closes behind you, there are only two ways to solve this problem - complete the experiment or find a cunning alternative.

Now you have to kill the ghouls that the dead employees have turned into and explore the terminals to understand what exactly happened here.

Way out of the situation 1. This is to install all the reagents + radioactive isotope in the correct order. In fact, in different parts of the building and in different places there will be many different reagents that you will need to scan as you go through to understand which one you need.

Cambridge Polymer Laboratory in Fallout 4

When everything is completed, Molly will say that you must show the results to the director and will take him to his office - naturally, the director has also turned into a ghoul and you need to kill him.

Way out of situation 2. We are looking for Bergman's terminal, which is located in laboratory C3, and we remove the blocking, but in this case, protective systems are activated and Molly becomes hostile and turrets also appear. After killing the secretary, we take the key to the director's office and go there.

Reward

For this task in Fallout 4 - Cambridge Polymer, in addition to loot from enemies and surrounding chests with cabinets, you will receive unique power armor, or rather a breastplate, which will have a special name and some of the non-standard effects.

Complete walkthrough of the Cambridge Polymer Laboratory quest for the Underground in Fallout 4 | The fastest The way to remove the lock is not to leave the terminal and select “Defensive systems of the factory.” Now you can leave the laboratory without any problems.

Return to headquarters

Next, you will again need to talk with the synth, who will advise you on the next steps. You will have to spend some time with the Father, completing two Institute tasks - “A New Look for Humanity” and “Mass Fusion”. After completing these quests, the synthetic will ask you to return to the room. In it you will meet Z1-14. He received a message about the Brotherhood of Steel's planned attack on the Underground. Return to headquarters and talk to Desdemona. Be prepared to defend. This will begin the next quest “War End”.

Collection route

We go to the Cambridge Polymer Laboratory and talk to Molly, who will invite you to participate in some piezonuclear research. Now we follow her to a huge room with terminals.

It should be noted that there are a lot of mobs everywhere throughout the back. Your goal is the terminal at the observation window and among the computers. According to him, you should collect: Unknown sample 3111, Unidentified sample 611, Isotope U-238

We go to the left room on the other side of this room until you see a large hall with stairs on the right. Go to the far left room and pick up a protective suit and a jar containing Sample 3111 with green lines on the body.

Now exit and go into the next room, and go to the Isotope Storage Department terminal to unlock the door where the isotope will be located.

In the main hall, to the right of the stairs, go through the door and along the corridor into the next room with radiation. Put on a protective suit if there is no other protection, and on the opposite side take the Isotope from the shelf.

Now return to the main hall, go up the stairs and turn left, walk along the broken cornice and hack the terminal by the door. The lock is complex, so if you don’t have the Skill, open the console ~, left-click on the terminal and enter unlock and the terminal number along with brackets, which will be reflected in the center of the console, unlock (0017660e)

Enter the room and take the unidentified sample 611 from the table near the terminal.

In general, there are a lot of unidentified Samples in the laboratory, but only these two and an isotope are required for armor. We return to the room with computers and a terminal. Place two Samples in the holders to the left of the terminal itself, and the Isotope in the holder on the right at the far end.

Open a terminal and click first “Scan downloaded items” and then “Run program”. We approach the far window behind the computers on the right against the wall and take the torso.

But that's not all. You won't be able to use it. Return to Molly and tell her the project is complete. She will take you to the director, praise you and... find out for yourself, just search his office thoroughly;). After this, the quest will be completed, you will gain experience, and then you can return and put on the torso. This is what it looks like as part of the T-60 armor. Let him be happy :)

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 easy).

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