Return to headquarters

Return to the Underground Headquarters and speak with Desdemona. Move to the Institute and meet with Liam to give him the password. Follow to synthetics for updates. Z1-14 will take 24 hours to think about the next step, so you will have time to complete other missions. But you can just take a break or sleep.

How to complete the task "Cambridge Polymer Laboratory" in Fallout 4?

16/02/2016

In Fallout 4 "Cambridge Polymer Laboratory" the passage of the quest is to collect a unique Piezo-nuclear power equipment. Travel to Cambridge (Commonwealth) and enter the laboratory. Find the room in which the terminal is located and see what components you need to get to create the armor. Gold, lithium hydride and an isotope of uranium-238 are hidden in the laboratory, so they are not difficult to find.

All of these materials are inside the laboratory and are not difficult to find. Then you need to go to the device for working with isotopes and insert the found metals in the following order:
- gold (object no. 611) - in the left slot;
- uranium - in the right socket;
- lithium (object no. 3111) - in the left socket.

This will create a Piezo Nuclear Armor that can be picked up. Now the secretary will let you out of the laboratory without making too much noise. But the director will have to be killed. At this point, the task will be considered completed.

Collection route

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

It should be noted - there are a lot of mobs all over the back. Your goal is a terminal at the viewing window and among computers. According to his data, you must collect: Unknown sample 3111, Unidentified sample 611, Isotope U-238

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

Now exit and enter the next room, and head to the Isotope Storage 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 take Isotope from the shelf on the opposite side.

Now return to the main hall, climb the stairs and turn left, go along the broken cornice and hack the terminal by the door. The lock is complex, so if there is no Skill, open the console ~, click LMB 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)

Go into the room and take the unidentified 611 sample from the table at the terminal.

In general, there are many unidentified Samples in the laboratory, but only these two and an isotope are required for the 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 to the right at the far end.

Open the terminal and click first "Scan loaded items", and then "Run the program". We approach the far window behind the computers to the right of the wall and take away the torso.

But that's not all. You cannot 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 quest is over, you will get experience, and then you can return and put on your torso. This is how it looks in the T-60 armor. Let her be happy 🙂

You will be prompted to download the "Virus" at any of the terminals of the Institute. This, in turn, will launch the new Underground and Undercover mission.

Step by step guide to download virus:

1. Find any terminal in the Institute
2. Insert holotape ([R] button)
3. Select "Virus" from the list
4. Click all the items in the menu - Network Scan / Message from Volume / Copy encrypted message.
5. Return to the main menu. A new line should appear in it about an urgent answer - open - done.

The answer will say the meeting place. We follow the marker on the compass and meet Liam:

After the conversation, he will offer to meet with "his synth", we communicate, we find out that they have 13 more synths who want to escape from the Institute. And Liam has an idea how to send everyone to the surface at once, but this will require our help - to get the details of access to the old security system of the Institute of Technology - "Code Defender", which are located somewhere in the Commonwealth.

We go to the subway, talk to Desdemona.

She will ask you to leave a report at the PAM terminal - let's go to it.

We select "Open report about the Institute". Then we talk to the PAM robot, it stands nearby (note: the PAM terminal and the PAM robot are different things).

We are told the place of the next visit - "Cambridge Polymer Laboratory" ", we go there.

In the building we are met by the robot Molly (a rather funny robot who will give an additional task “Cambridge Polymer Laboratory”). After talking with the robot, we are looking for such a room:

To get there, you will need to either hack the "Difficult" level terminal, or run a little more around the building, and find a passage to the room through the upper floor (there will be a hole in the floor).

We get to the desired terminal - there will be many items, we need a "Request for a password (archive)".

To leave the room - open the door using another terminal in the room.

We return to Desdemona, we talk. Then we return to the Institute and talk to Liam and Z1-14.

The latter will say that he needs time to talk to friends. We sit on a bench next to it and scroll through it for 24 hours. Talk to Z1-14 again.

He will say that synths are ready to fight for freedom, but they need weapons that they, in general, can make themselves, but they need materials.

We leave for the tunnel and kill the guards.

Going back to Z1-14, he will tell you that they are starting to assemble the weapons, but it will take time.

Further, the task will be "on pause" until the Run task is completed. After completing this task, immediately after the meeting of directors, a synth will come up to you and say that in your room later - you urgently need to go there. It is clear that there is no flood, just Z1-14 needs to meet with us.

He will say that the Institute has secretly transferred the location of the subway base to the Brotherhood of Steel, and they urgently need to be warned. We leave for the subway and speak with Desdemona.

This completes the task.

Reward

• 400 (?) Experience
• Nail gun
• Rail Nail (56)
