The Sabotage quest inStarfieldis the penultimate mission for Ryujin Industries. Along this journey you’ve participated in corporate subterfuge, stealth missions to investigate a possible mole, and eliminating Ecliptic mercenaries. On each of these missions you’ve had to make choices that directly affect the NPCs involved.
Sabotage is one of the most difficult missions in the Ryujin Industries quest line. There are key moments where your actions have consequences, and how you proceed through the quest will decide the fate of either Masako or Ularu. Who will win and who will be sacrificed? It’s up to you.

How To Start The Sabotage Quest In Starfield
After completingThe Key Ingredientmission,Veena Kalrawill leave to work on theProject Dominion Internal Neuroampand Masako will send you to meet with Dalton,who has information about the mole.
His response regarding the mole will differ depending on the choices you made earlier in theGuilty PartiesQuest.

Dalton will tell you his findings, and then lead you to a meeting with Masako. Once the meeting is over, head down to Research and Development (R&D) and talk to Veena.She will get you fitted for the Internal Neuroamp, which unlocks the Manipulation ability.
How To Complete The Neuroamp Test
At the end of the meeting,head to R&D and talk to Veena. If you remember from the previous quest, you are Ryujin’s guinea pig for testing the neuroamp.
When you wake up after the procedure,talk to Veena,and she’ll have you test out the neuroamp’s abilities on DeMarcus.Head up to the platform above, and DeMarcus will be standing in the room below, waiting.

Open up your Scanner, select your target, then activate Manipulation.While it’s still active, direct DeMarcus to first pick up thekeycard on the table behind him. Use the neuroamp one more time tomake him open the door.
Veena warned you that the effects are temporary, so if you wait too long,the manipulation will fail, and you’ll have to start over again. However, if Manipulation fails in the field,you won’t get another chance.

Once the test is complete, discuss with Veena and DeMarcus briefly about the neuroamp,then head back to Masako.
How To Infiltrate Infinity LTD
Meet again with Masako and Ularu. They’ll go over your options forgetting inside Infinity LTDon New Atlantis and acquire any and all research they have done on Project Dominion. Whichever path you decide on,you’ll have three main objectives to complete:
There will be three main ways to break into the building:stealth using the roof access, go undercover using an alias,orkill everyone

Whichever option you choose during the conversation, Ularu gives you some gifts for your assignment:
If you want toprove that Ularu is the mole, you must first take the slate to Dalton. He’ll find that she plans to use her program to frame Lucas Drexler and Masako, so hegives you a replacement slate with a revised program to use instead.

Otherwise,if you’re siding with Ularu, head straight to New Atlantis.
How To Complete The Quest Using Stealth
Put on theOperative Suit and Helmet, which makes you25 percent harder to detect, and head to the roof access to the side of Galbank,leaving your companion behind.
We recommendupgrading your Stealth to at least level threeand saving your game should you get in a tight spot and need to reload. You can also use aids like the Reconstim that grants you -30 percent movement noise for ten minutes.

How To Disable The Heating System
To shut off the heating system, first go straight ahead and through the vent. In this room you’ll find a large spinning fan.You need to drop below the fan, so use your new neuroamp tomanipulate the guard downstairs to turn off the fan.
Now you can drop safely and head towards the heating system.There will be no guards between you and the heating system controls, so this part should be simple.

How To Infiltrate Lucas' Office
Now you can start making your way to Lucas’ office.His office is on the Executive Floor, which is down just one level. Use the ventilation shafts,keeping low and quiet so you don’t get detected.
If you sabotage the heating systemhis door lock is only Novice level, but if you don’t,it becomes Expert level and much harder to pick.

Go inside, grab thedigipickon the whiteboard, then unlock his computer andrun the Overseer program.
Descend To The R&D Floor
After you’re done, you now need tostart your descent to the R&D floor. This may be trickier as it’s more floors to traverse,but attempt to utilize the ventilation vents and platforms as much as possible.
You can also use the clouds of gas as cover, butmake sure you have aids that cure lung damage with you, as the suit doesn’t protect from corrosive gases.

Open Lucas’ door and to the left, while in stealth mode,jump down to the rafters below you. Go right across the beam to an air vent. Head inside and down till you’re in a bathroom.
This part is very difficult to pass, even with level four Stealth. There are at least two guards that patrol outside the bathroom, and a few more on the other side of the hallway,and they’re all trigger-happy.
If you have trouble sneaking past the guards here, your best bet will be tomake a mad dash down the hallway, into the cafeteria, then sprint left, and go into the vent.
The guards will yell and give chase, but once you’re in the ventthey should no longer pursue. Head down through the vent and drop onto another platform.
Look for theoffice with the birthday decorationsand go that way, then turn right. Keep following the paths to the right, then left again till you find anair vent with the quest marker on it.Go inside then down into the elevator shaft.
Look for your quest marker - that’s where you need to go.Descend slowly to avoid any broken bones, then go through the vent to get out of the elevator shaft. It’ll be dark and hard to see, but the quest marker will be on it.
This next part is tricky. You have tojump across from the vent to the pipes. There is a guard below you,but it’s super dark, so he shouldn’t see you.
You can useManipulation on this guardto make him go away. That way he definitely won’t see you.
You are now on the R&D floor. You have two objectives here:Run Overseer on Faye’s computer and steal the prototype.
Go left, sneaking across the pipes, thenjump over the hallway againand go into the vent.At the end of the vent is a hatch. Drop down, then keep crouching as you go up the stairs to the right.
The guards on the other side of the glasswon’t see you as long as you stay in stealth mode. At the top of the stairs isFaye’s computer. Run the Overseer program,grab the R&D ID card off her desk, then head back down the stairs, and go through the door on the left.
Go through the door at the end of the hallway slowly. Look up, and you’ll see a turret across from the red secure door. Beyond that door is the prototype,but you have to disable the camera first.
You can eithershoot it with a silenced weaponor useManipulationon the guard above to turn it off.
If shooting the turret alerts the guard,run back and hide in the vent till the coast is clear.
Once it’s clear, go into the room with the prototype using the R&D keycard,closing the door behind you. Before you grab it, however,close the blinds and disable the alarm, otherwise you will get caught.
Once you’ve done that, take the prototype, andget out of there. Make your way back through the vent, over the pipes, and to the elevator.Take the elevator down to the lobby, leave Infinity, and head over to SSNN.
How To Complete The Quest Going Undercover
If you would rathertalk your way throughto your objectives, after disabling the heating system head back outside, andspeak to Dezi at the front desk.
She’ll direct you to go up toMarketingto meet withAelys Ortiz. After your brief meeting with him, he will leave which gives you freedom to walk around.
If you didn’t sabotage the heating, you’ll have more NPCs to deal with, so it may take a lot of talking to get to where you need to go.
Once you’ve talked your way through and completed your tasks,give the information to SSNN, then head back to Neon.
Secret Third Option To Complete The Quest
There is a third task thatwas not discussed in your meeting with Masako and Ularu. Although they prefer that there isn’t a body count, you do have the option to go in and just kill everyone.
The consequences will be minimal,and you may end up getting more XP and credits due to being able to loot freely.
Either way, once you’re done, and you have the information,head over to SSNN.
Who Will Be The New CEO Of Ryujin Industries?
After speaking giving the information toDavid Barron at SSNN, head back Ryujin Tower on Neon to watch his broadcast. Depending on the choices you made,either Masako will remain as the CEO or Ularu becomes the CEO.
