Detailed walkthrough[]
首次进入劍橋聚合物研究所后, the Sole Survivor is greeted by a Miss Nanny robot named Molly. She asks if the Sole Survivor has come to fill a job position. Answer yes and Molly will give the player character a one question survey for qualification, asking whether or not the player character has any research experience. She will assign a job and provide a uniform (set of clothing and items) based on the answer given:
- Expressing confusion: Janitor, a mop and a green mechanic jumpsuit.
- Yes: Researcher, a lab coat and clipboard.
- "You need me" (Charisma check): Sales Coordinator if successful, a dirty tan suit and a pen. Lab Assistant if failed.
- Threaten: Security, dirty army fatigues, a baton and a pair of patrolman sunglasses.
Molly will then ask if the Sole Survivor would like an orientation, which is optional. If they agree, she will move into a side room with a broken slide projector and relate the history of the company. The Sole Survivor is asked to change into suitable attire and Molly leads the player character through a changing area with sets of lockers, then the Survivor is told to proceed to the clean room.
- Note: 这是最后的不做任务离开的机会。 居礼 has a significant affection boost (35 points) for completing the research, 所以强烈建议找她过来。 另外，好感度的增加需要完全完成研究，所以不要破解安保系统。
As soon as the Sole Survivor enters the clean room, Molly locks the door and informs the player character that Director Elwood has issued a mandatory overtime edict to the staff and that no one may leave the laboratory until the project has been completed. The room will then fill with high-level radiation, though Molly will decontaminate it shortly. The player character may then ask Molly questions, but her responses are generally that the player character should look at the research already done and see if it can be moved forward.
Just past the clean room, the player will come to a room with a terminal directly in front and a large machine called the Polymer Coating Applicator filling the right side of the room. The terminal will have the research data of the experiment that's been performed up to this point.
To complete the project, the Sole Survivor must supply the applicator with the reagents lithium hydride and gold in addition to the radioactive material, U-238. Sitting right on the applicator is a silver canister that contains unidentified sample 11317, which when inserted into the applicator will identify it as hydrochloric acid. The Sole Survivor must explore the rest of the facility and find the components for the project.
There is a door leading from the room with the applicator out into the main atrium, which is filled with feral ghouls. Roughly 8-10 ghouls will attack at once, but once they are dead, the Sole Survivor is free to explore with only occasional interference from stragglers.
Entering the atrium there are two doors straight ahead. The storage room on the left contains unidentified sample 3111 (lithium hydride). The adjacent door leads to another small lab containing unidentified sample 413 (gallium). In this room is a hole in the wall leading into the next lab, which contains unidentified sample 65 (tungsten), a window to view into the containment room, which contains the U-238, and a wall-mounted terminal that opens the containment room. Opening the room causes alarms to sound and a glowing one to rise out of the standing water in the containment room. The containment room can be accessed via the door on the ground floor at the bottom of the stairs, to the left of the door leading back to the applicator room.
Up the stairs on the second level and turning around, there will be two doors at the end of walkways on either side. At the end of the left walkway is an office space in which the player character will find unidentified sample 49 (cobalt) sitting on a desk. Near this desk is a ramp leading into the ceiling ducts, which will grant access to the aforementioned right hand office, if one is unable to hack the Expert-level terminal at the door outside. Deal with the ghoul inhabitant, disable the tripwire and mines before they can go off, then look around the lab.
This is Wilfred Bergman's lab and the final reagent, unknown sample 611 (gold), can be found sitting on a desk next to a terminal. At this point, one has two options:
选项一：完成实验[]
Return to the applicator room and insert the components. Insert unidentified sample 3111 (lithium hydride) and unidentified sample 611 (gold) into the chemical reagent slots on the left and U-238 into the isotope sample slot on the right. Use the terminal to start the fabrication process by selecting "Run loaded fabrication routine".
Watch the polymer lining be applied to a piece of power armor, producing the Piezonucleic power armor, a unique Legendary power armor piece. Collect it on the far right and present it to Molly.
With the project completed successfully, she will unlock the clean room, adding that the director will be impressed and will want to meet the Sole Survivor. Following her will lead to the director's office on the second floor of the main entrance area. Upon opening the door, the director, now a feral ghoul, tries to attack the Sole Survivor. Molly intervenes, re-informing the director of company policies about assaulting coworkers before killing him with her saw arm. If the Sole Survivor has already killed the director before this, 她会带老冰棍前往管理者的办公室，并向已经变成尸鬼的管理者汇报，付清薪水（战前货币），之后关机自杀。The piece of power armor remains available for the Sole Survivor to use as they see fit.
选项2：强行离开[]
玩家可以在伯格曼博士的实验室内激活终端机并访问设施防御系统目录，这将使用紧急通道，从无尘室打开一条离开实验室的路。但同时这也将激活实验室内的所有防御设施，包括炮塔和茉莉，消灭它们就可以离开了。

Quest stages[]
Notes[]
- The player character can choose to destroy Molly before entering the clean room. Subsequently entering the clean room will cause Molly to respawn, lock the door and activate the decontamination process.
- Occasionally Molly will become hostile when opening the clean room doors. The key to the director's quarters will be in her inventory when searched. This can complete the quest, but one can still complete the research project afterward and get the power armor piece.
- 玩家进入劍橋聚合物研究所后 the Piezonucleic power armor chest piece model is set as dependent on the player character's level from the moment the player character steps in the interior cell (the "labs" collectively).
- A segment of the Railroad quest 地底潛入行動 sends the Sole Survivor to Cambridge Polymer Labs to retrieve a password from Dr. Bergman's terminal.如果这一任务尚未完成，玩家将难以逃离实验室。
- 攻击炮塔将会导致茉莉的敌对。
- If the player does not follow Molly to the director's office after completing the research project, Molly can be heard making apologies for the director's condition, but no fight will be heard, nor will she comment on him attacking the player character. Upon entering the director's office after Molly's shutdown, he will be dismembered on the floor anyway.
- Curie loves it if the player character opts to complete the research.
- If the player character chooses option 2, but does not loot Molly's body, her corpse may despawn after leaving, making it impossible to enter the director's office without picking the door.
- If the player character hacks Molly and shuts her down prior to entering the clean room, this may cause the quest to remain uncompleted despite obtaining the unique power armor. This can be fixed by destroying Molly and collecting the key to the director's quarters from her inventory.
Bugs[]
Rarely the player character will be unable to pick up the radioactive isotope U-238.[已验证]- The player character will be unable to pick up the unidentified sample 3111, which is required to successfully complete the experiment. While the model for the sample canister (base ID 000a50f8[PP]) will appear correctly and hovering over it will display the correct name, actually picking it up will not raise the prompt message "Unidentified Sample 3111 added" nor trigger the correct audio cue for the picking up of the item. No unidentified sample 3111 (base ID 000a50f7) will be present in the Miscellaneous tab of the inventory, nor will it be presented as one of the options to be placed in the reagent tubes. A solution is to use player.additem 000a50f7. That command will place the item in inventory and allow placement of the sample in the reagent tubes for identification. Note however that doing so will not remove the item from the inventory, and it will still be presented as a choice for the second tube. Using player.removeitem 000a50f7 will solve the subsequent issue, but note that taking the canister (which remains base ID 000a50f8 when placed in the tube, both before and after identification) back out will once again not add the sample item back into inventory. [已验证]
- If the player places unidentified sample 611 into a receptacle, scans it to turn it into gold, but then picks it up out of the receptacle, the item can change into a misc item called "NONE." Thereafter it does not appear as gold, and thus the player is left unable to complete the quest. The solution is to re-add the gold sample to the player's inventory with console command player.additem a50f5 1, and to remove the "NONE" item with player.drop 9c2cb 1.[已验证]
- After completing the quest the player character will be stuck with the rest of the components (Gallium, Cobalt, Hydrochloric Acid and Tungsten) in their inventory. The solution is to ask a companion to inspect the reagent in the tube then Inspect Chemical Reagent will appear. One can then place another reagent in the tube while the first reagent is still in the tube. Keep asking a companion to inspect the tube, then place another reagent in the tube until all reagent quest items are removed from the player character's inventory. Another solution on PC is delete the items through the command console, using the command player.removeitem <base ID> 1.[已验证]
- After Molly shuts down when completing the quest, the quest log will mark the research portion of the quest as failed. The player character will still have the Piezonucleic chest armor. One can open console and use the commands CompleteAllObjectives 284bc or CompleteAllObjectives DN015 to complete the quest, but one will be need to used before Molly shuts down, or the quest will still be marked as failed.[已验证]
- If the dialogue with Molly is bypassed (e.g. from sneaking past her or ignoring her) and the terminal in the Director's office (master locked) is accessed and the lockdown cancelled, the first stage of the quest will no longer be able to initiate and the only option to complete the quest will be to trigger security and kill Molly.[已验证]
- When closing the door to the containment chamber after retrieving the uranium (e. g. to silence the alarm) a companion may get stuck in the chamber, even after opening it again, refusing any movement command through the (theoretically open) door.[已验证]
- After creating a prototype, a quest notification for "Complete the research project" may appear, but the quest stage will not be marked as completed or "greyed-out" in the Pip-Boy. One can still speak to Molly (if not hostile) and proceed to the Director's office to complete the quest, but this will cause "Complete the research project" to be marked as failed in the quest summary in the Pip-Boy.[已验证]
- It is possible to complete the quest without doing the research project. Kill the first Molly that appears, and another Molly will appear from a normally-inaccessible room. Collect the CPL Director's key from the first Molly, unlock the director's room on the second floor, and kill the director, then go back and kill the second Molly. The quest will then complete.[已验证]
- When Molly starts the intro, if one walks straight to the lab door and unlocks it via picking or hacking, gets all the substances and manufactures the prototype and then goes back and completes the tour, they will not be able to complete the mission.[已验证]
