Fallout New Vegas DND Player's Guide, a comprehensive 120 Page handbook for a homebrew 5e Campaign! Introducing my homebrew DND 5e Fallout New Vegas Player's Guide, featuring 120 pages detailing the backstory of the Mojave, 13 unique classes, and extensive background on the various factions that inhabit New Vegas.
Once you unravel the mystery of Valkyrie's past, the plot will advance into the Fallout 4 main story, where you can work with a familiar face and some new ones as well to complete the Fallout 4 main story line in your own way and reform the Institute if you want. The mysterious serumis a semi-unique consumablein Fallout 4.
A serum unique on a wasteland scale, this container contains a retrovirus capable of returning the super mutantBrian Virgil back to his human form. Although such a cure was theoretically possible before the Great War, reversing the mutation was believed to be an unachievable goal, as the counter-virus would require both a preserved sample of the original DNA and a way to neutralize the FEV. Neither were believed to be possible to achieve, as FEV eliminated the original DNA and no method existed to remove the virus. At least, until Brian Virgil worked on the Institute's FEV project, advancing the understanding of FEV's capabilities beyond pre-War knowledge.[1]
The serum is a retrovirus,[2] using recombinant counter-intron sequences and transcriptive exon strands[3] together with a genetic resequencer to counteract the specific strain of FEV that Virgil was infected with, restoring him to a human state not by reverting to the original DNA, but recreating it using the mutated DNA as basis. The experimental state of the serum and a buggy resequencer do not result in a perfect restoration, leaving portions of the mutated code untouched: Virgil retains some muscle mass after the transformation.. And his baldness being apparently cured. However, the cure's effectiveness is limited to the single specific strain Virgil infected himself with and generalizing the formula would take years, if not decades.[4]

ZAX 1.2: '{157}{}{My research into the Forced Evolution Virus, or FEV, indicates that it is a shifting-absorptive virus. It copies DNA patterns much like RNA, storing these patterns in exons.}'
'{158}{}{These exons, combined with the FEV, are re-injected into the host cells in typical viral infectious fashion. This causes the host cells to 'regenerate' their DNA.}'
The Vault Dweller: '{159}{}{How do you catch FEV?}'
ZAX 1.2: '{162}{}{FEV is not 'caught', per se. It is not air-transmittable. Typically, infection is through injection, or direct physical contact with an FEV sample.}'
The Vault Dweller: '{164}{}{Why isn't FEV affected by radiation?}'
ZAX 1.2: '{166}{}{The FEV is a megavirus, with a protein sheath reinforced by ionized hydrogen. It is therefore capable of absorbing neutrons without becoming radioactive.}'

ZAX 1.2: '{169}{}{The FEV is pre-programmed with introns of corrected DNA appropriate to the proper type of species. It therefore attempts to correct the DNA of the individual.}'
'{170}{}{However, as the FEV is partially reliant upon the DNA of the individual, and also includes portions of its own recursive code, the effects can be unpredictable.}'
'{171}{}{When inoculated into an individual with significant genetic damage, such as through radiation, it will cause the body's systems to suffer massive overhauling, leading to organ failure and death.}'
'{172}{}{In a genetically viable individual, it re-writes portions of DNA, causing accelerated mutation, usually leading to recursive growth due to the FEV's own patterns.}'
'{173}{}{This recursive growth leads to an increase in muscle and brain mass, but is often accompanied by disfigurement and damage to existing neural patterns, causing loss of memory.}'
The Vault Dweller: '{174}{}{What potential long-term side effects exist?}'
ZAX 1.2: '{178}{}{As the FEV causes constant regenerative update to DNA, it would effectively render the subject largely immortal, as cell death would be offset by augmented growth.}'
'{179}{}{Additionally, as the gametes of the reproductive system consist of 'half-cells' using split DNA, they could be perceived as 'damage' by FEV, which would 'repair' them, rendering the subject sterile.}'
'{180}{}{However, as my laboratory facilities are damaged beyond repair, this is conjectural. I cannot offer physical proof. You will have to, in human terms, 'take my word for it.'}'
The Vault Dweller: '{181}{}{Could FEV mutation be corrected with a counter-virus?}'
ZAX 1.2: '{184}{}{No. FEV does not retain unaltered original copies of the subject's DNA. Only a virus which re-infected the subject with original DNA could reverse the effects. Additionally, there is no known way to remove the FEV itself.}'
(ZAX.MSG) - ↑Sole Survivor: 'It'll work. Don't worry.'
Brian Virgil: 'I hope so. We just have to let the retrovirus run its course. Virgil_Supermutant: I'm going to rest for a while. Come back in a few days, maybe a week, and.. well, I guess we'll see.' - ↑Brian Virgil: 'Retrovirus has matured nicely. Density gradient is high.. Recombinant counter-intron sequences look stable.. Transcriptive exon strands have formed..'
- ↑Brian Virgil: 'Welcome back. It needs some refinement, but I think we can consider my serum a qualified success.''
Sole Survivor: 'This is a 'qualified success'?'
Brian Virgil: 'There were some side effects to the process. I seem to have hair again. And I've retained some muscle mass. The genetic resequencer needs more work. Still, I take your point. This is a significant advance. But only for one strain of FEV. It will take years, perhaps decades, to generalize my formula.'
Mysterious Serum - The Fallout Wiki
Ready to reinstall Fallout 4 and experience a whole new quest line with a bunch of new companions? Project Valkyrie re-tools much of the end game and gives you a whole new storyline to work through.
In order to use Project Valkyrie, you need to have the Outcasts & Remnants mod to be installed first. The Fusion City mod is recommended, but not required. Your character also needs to be able to pick master locks or you can't complete the quests.
Because the mod quests intersect heavily with the main vanilla quests, there's possibility for conflicts to arise. If you run into a problem where a quest isn't finishing properly, talk to one of the new companions and pick the option to end or restart the current quest.
Besides the new quests and companions, Project Valkyrie significantly alters how the end games plays out. You no longer have to pick one specific faction to work with, and you aren't railroaded into help that faction annihilate the others.
Starting Project Valkyrie
This mod's primary quest line is tied closely to the vanilla game's Secret Of Cabot House side quest, which has to be started first to gain access to the new Project Valkyrie content.
If you've already completed this quest and can freely enter the Parsons State Insane Asylum, just head straight there to find Valkyrie. Talking to her begins the In A Darkened Room quest.
If you haven't started or completed the Cabot content yet, first travel to Cabot House, which is found north of Goodneighor and west of the Old North Church.
The door is locked and can't be picked, so talk to intercom on the left side. If you have the proper Charisma skills, you can persuade them to let you in.
If you fail the persuasion attempt, instead find the ghoul named Edward first and he'll tell you to meet him at Cabot House. He can spawn randomly at Bunker Hill, the Third Rail bar, or Dugout Inn.
Kick off this weird immortality-themed quest by accepting the job to track down a dead courier and pick up his serum. After the battle with the raiders, bring the serum back to start the Emogene Takes A Lover quest.
When Edward takes you upstairs, hack the computer on the back wall near the second staircase and read the entry labeled Patient Log S18. This entry updates the main Project Valkyrie quest In A Darkened Room.
Before you can actually get into the Asylum to meet Valkyrie, you need to have Jack unlock the doors. Keep completing tasks for Edward until you finally reach the Secret Of Cabot House quest. During that quest, Jack will unlock the Asylum.
Once inside, make sure to help Jack unlock the doors and activate the elevator, or you can get permanently stuck in the basement with no way to leave after finding Valkyrie. The only way to leave the building at that point is to use console commands to warp to a new location.
In A Darkened Room
For this first quest of Project Valkyrie, travel to the Parsons State Insane Asylum at the northeast end of the map.
Valkyrie herself is found in a locked room in the basement (you have to travel through the gap between walls and jump down the giant hole to reach this area).
Access Nurse Deesil's terminal to unlock the door, and then leave the Asylum. Note that have to actually walk by the front door to the Asylum to trigger the end of the quest, so just warping out isn't immediately helpful unless you walk back.
Be sure to talk to Valkyrie to get a dose of super charged Serum (and to give her some clothes and a weapon)!
Malpractice
Talk to Valkyrie again and ask how you can help to kick off the Malpractice quest, which will have you traveling to different medical centers in search of answers.
Travel to the Medford Memorial Center, which is directly next to the Malden Center station and southwest of Greentop Nursery. This area is filled with suicide bombing super mutants, so you'll want to wear your power armor. Pick the master locked door and head up to the top section to access the terminal and find out about Valkyrie's abduction.
Next, travel to Kendall Hospital (north of the Institute and east of Cambridge Police Station). Be ready for raiders and deathclaws! In the basement, look for a terminal behind a giant hole in the wall and read the notes.
Finally, go to Mass Bay Medical (southeast of Vault 114 and Swan's Pond). Head up towards the top of the area and look for a back room with a terminal located above the power armor station. Read through those files to find out how Valkyrie was kidnapped.
Heir To The Throne
Anytime after reading the final terminal in the previous quest, talk to Valkyrie again and ask for another job to start this quest line.
Head to Back Street Apparel and look for the blue door labeled Valkyrie's Apartment (right next to Club Snuggle). Pick the novice lock and head inside to raid the apartment, which has work benches, a power armor station, and can now serve as your home. Reset printer epson l310.
Grab the Note From Vanessa on the dresser chest in the bedroom and then talk to Valkyrie again. Travel to the USAF Satellite Station (southeast of Robotics Disposal Ground).
Be on the lookout for laser tripwires in here! Talk to the H.A.L.L.Y robot to get the Liberty Prime overwrite codes and then grab the shipping receipt off the dead body. Talk to Valkyrie again to complete the quest.
From this point onward, Valkyrie will offer repeatable side quests if you initiate dialog.
Wag The Dog
This quest intersects with the Brother Of Steel end game state and sees you taking over control of the faction. Its best to start this quest after completing the vanilla Show No Mercy quest so Liberty Prime is already re-assembled.
With the Liberty Prime override codes in hand, travel to the B.O.G. Bunker south of Oberland Station and chat up Fiona McBride in the lounge area of the sub-level.
Talk to the kid named Owen in the next room and take him to the safe house marked on your map (and for the love of God, don't give that child a mini-gun when he asks for one). Talk to Owen's mom -- who it turns out is none other than Sarah Lyons -- and then fight off the Brotherhood invaders.
Read the info on the terminal and talk to Sarah again, then follow the map markers to kill the Brotherhood members. Read the note labeled Orders From Kells and then show it to Owen's mom.
Deal with the Brotherhood ambush situation, and then press the glowing red button above the toilet to open a secret back room. Read the terminal and then chat with Maxson.
From there, its up to you whether to go the peaceful or violent route with Sarah. Follow her around and talk to Captain Kells and then Proctor Quinlan. Chat with Fiona again to finish the quest.
At this point you can now talk to Fiona to initiate the Peace Through Superior Firepower side quest.. which has you recruiting Liberty Prime as a companion.
Yes, the insane Democracy-spreading robot Liberty Prime is now your companion. Have fun annihilating the wasteland! Obviously he can't enter buildings however, so he'll hang around outside when you enter an interior area.
The Revolution Will Not Be Televised
For the final main quest of Project Valkyrie, talk to Sarah again and then go chat with Carter at Club Snuggle next to Valkyrie's apartment.
Fallout 4 Give Serum
This quest has you taking control of the Institute, so its best to start before fully completing the main Institute quest lines of the vanilla game.
Fast travel to Hubris Comics and follow the map markers to get the teleporter gun components, then take them back to Carter Beckett. Walk to the pinup room in the basement of Club Snuggle and talk to Dr. Zimmer, then return to Carter again.
Go inside the Institute and load the holotape into the terminal in Dr. Ayo's room. With the teleporter gun equipped, initiate conversation with Clayton Holdren and decide whether to kill him or teleport him elsewhere. Repeat this process with Isaac Karlin and Alana Secord, then go back and talk to Carter again.
Now just follow the quest markers to talk to Sawyer, Sarah, Desdemona, and Preston to take control of the Institute (if you really hate Preston Garvey, be sure to teleport him to prison). From here on out you can use the Director's room as your home base.
After completing the main quests, repeatable side quests become available by talking to Sarah, Valkyrie, and Owen, and by opening the terminals in each area of the Institute.
You can also now recruit the following new companions:
Experimental Serum Fallout 4
- Synth Nate in the SRB Lounge of the Institute
- Synth Gloria at the firing range in the Advanced Systems room of the Institute
- Synth Nora in the steam shower section of the Director's room
