Introduction

This guide outlines the actions and their sequence for completing Mountain Master Heist stealthily and the location of the main facilities for interaction.
This guide may be updated and supplemented.
At the end of the manual there is a section with layouts of all key facilities in the heist. If I haven't attached a screenshot of the location of any item, then you can find its location on these layouts.

Pre-Planning

In the pre-planning, the optimal choice for me was:

• Deployable - Body Bag Case - Terrace;
  
• Hacking - Overclocking;
  
• Insider help - Mark the correct bookshelf (will be highlighted in yellow);
  
• Backup - Spotter - Balcony.

Asset Body Bag Case caused by a large number of civilians and guards of the triad without pagers. In addition, I took 2 Body Bag Cases, which made a total of 11 Body Bags.
The second important asset - Mark the correct bookshelf - is needed soyou don't have to move them all, because the guards (as in the 3rd day of the Framing Frame) are triggered by the shifted bookshelves.
Other assets can be changed as you wish.

Hall

1. After entering the hall, Locke offers 2 options: passing through the office and turning off the metal detector with passing through the frames. We choose the second option, because in the office there can be 2 cameras at once and 2 civilians sit, and sometimes 1 woman walks in front of the (only one) box that needs to be hacked.

It looks like a standard GenSec alarm box and is located in one of three places:


2. After getting into the passage with elevators, we need to turn off 3 boxes, but do it sequentially. You can turn off only the one that is green, and they will light up in turn, after turning off the previous one. That is, the shield that was inactive can become active after the previous one is turned off.
Each floor has 1 guard and 2-3 cameras. On the lower floor with a guard, you can disperse in the center using a cart with boxes, on the upper floor - you can’t.
All the places where the box appeared are indicated below:





3. When turning off the box in the garage (if there would be one), you should take the equipment (crowbar and glass cutter) from the trunk of one of the 3 vans, since you will still need to take it later.

The garage has 1 guard patrolling the entire area, 2 triad guards without pagers and 1-2 civilians. Don't leave corpses in the garage, the guard will find them.

4. Then we call a certain elevator to the lower floor.

After his arrival (10 seconds), you need to find an electrical panel (in one of the two rooms) and secure the elevator.

After we need to go up to the upper floor, open the elevator doors with a crowbar and go up on the zipline. If you're playing solo, stick to the left side (farthest from the wall) to make it easier to pass the guards in the penthouse.

Penthouse (entry)

1. After we went upstairs, unscrewed the grate - we need to get to the steel door to the pantry.

A civilian may walking nearby. So he can immediately be placed in a blue bag and left to rest in the pantry (no one enters it).
If you nevertheless rode the zipline on the other side, then after exiting the elevator shaft, a guard will walk on the left, and on the right is the path to the aforementioned civilian.

2. The next step is to turn on the floor lamp, which always appears in one place, so that the cradle will come to us (5-7 seconds).

There are always 2 men sitting next to the curtain, 1 guard with a pager and a woman running around, who you can bring along in body bag, since only she can detect us.

Penthouse (main part)

The largest and most difficult part of the heist. I recommend not to waste pagers until you reach this stage.
Not all guards in the Penthouse have pagers, but it's hard to tell them apart from those with pagers (unlike the Black Cat Liner), so it's best to avoid any of them.
Don't throw the Body bags or corpses off the balcony - now it raises the alarm!

1. The first thing I did during the passage was to look for the camera guard. In total there are 2 spawn locations for the camera room:
On the left side of the corridor closest to the cradle.
(sometimes the door appears from the side of the Lounge)

In the corridor behind the Mustang, closer to the office of the Yufu Wang (the place from the picture or exactly opposite).


2. Then we need to find the hidden server room. It is located behind one of the bookshelfs that need to be moved to reveal it (due to the asset, you only need to look at the bookshelf).
In total there are 3 places with bookshelfs:

• Next to the triads playing poker - 1 bookshelf
  
• In the Lounge room - 2 bookshelves (there always is one woman and sometimes man in a white suit)
  
• In the Yufu Wang office - 2 bookshelves

3. After we have found the server room, you need to find a note with a password (it will contain Chinese numbers, so we take the it with us) or just drill through the grate, which will take 125 seconds (with pumped skills of drill improving).
Moreover, you can use OVER9000, but I don't recommend you this way
The choice of how to open a server room depends on its location: if it's in 1st or 3rd places I have mentioned, you can risk putting a drill, eliminating one guard each, who are necessarily located in this area. If the server room is in a Lounge room, it's better to find a note.
The notebook can be placed in one of 3 places: on the kitchen table, on a sun lounger on the terrace, or on a cart in the hallway. All places are marked on the map.


4. The next step after opening the server room grating will be hacking the hard drive. Hacking must be done using the laptop of the Yufu Wang. It can be placed in 3 places: the bedroom, the office (they are nearby) or on the table in the Lounge room.
Both rooms are patrolled by one guard with a pager, who can be bypassed in the bedroom using a column or in the office using a table.

5. After hacking the hard drive, we send it down using the kitchen elevator, which is located next to the office. It is not necessary to break the doors, these rooms are connected by a ventilation hole. A guard with a pager from the corridor sometimes comes into the kitchen and walks it around.

6. Then you need to raise the alarm using the Fire Alarm, which can be located on the wall in the room or corridor. The location is marked on the map.

After turning on the alarm (it's still stealth), the guards with pagers will remain in place, and the triad guards - without pagers - will go through various corridors and rooms, so it's better to hide yourself and wait 1-1.5 minutes. For the same reason, it is better to hide corpses either in a room with cameras or in a server room.

Penthouse (end part)

1. After waiting some time after turning on the alarm, we need to seep into the Yufu Wang office, where there is a ladder to the roof:


2. Climbing up to the roof, you can see a helicopter and 5-7 guards patrolling the area, or standing in certain places. Some of them have pagers, some haven't.
The easiest way to kill the Wang catch him when he descends from the helipad and goes to inspect the territory in solo. Catching him when he is alone and out of sight of the guards is easy enough.
After the murder - we raise his key card, which opens the safe with gold, which is hidden behind the mirror (the location of the mirrors is indicated in the map):

Gold (4 bags) must be dragged to the cradle, kitchen lift or zipline (if the corresponding asset was purchased).
Do this carefully, because there are guards with pagers left in the Penthouse, who continue to follow the same routes.
Also, another key card is in one of two places (next to the poker table or on the kitchen table). With it, you can open the second safe (4 more bags of gold).

The escape point is also located in the cradle, so there is no need to go down. You can even put in an ECM and do a KEKW run, declassing all the guards on the way.

Layout of key facilities

Achievements

The first achievement is performed on the difficulty of Overkill or above and only with a stealth passage. To complete it, you do not need to complete the level to the end.

To complete it, you need to get to the stairs to the helipad and find the Keypad, interaction with which will begin a two-minute countdown.

During these two minutes, you need (without raising an alarm) to press 3 of the same Keypads located on the roof:


The second achievement is completed on the difficulty Very Hard or above and with a loud hike (it will become loud anyway during the achievement).

The essence of the achievement is to find the Gnome statue in the trunk of one of the cars (black or white SUVs) located in the parking lot and bring it to the helicopter (necessarily to the helicopter, the kitchen elevator will not give the achievement).
When you take the gnome out of the car, he will start yelling loudly and call for help, its alarm will go off, which will turn the heist into a loud one anyway. Even with ECM.

Conclusion

I hope my English was no worse than my explanation and you, dear readers, understood everything.
I accept comments and criticism.

@VooDoo this is an excellent guide. I really hope you create more guide for other heists. I love that you used photos for where things are instead of walls of text or a video like other guides. Please please please keep up the great work.

[Stray Cat, General Overkill]

I've found that the two swords in the hallway are actually labelled as artifact loot. Could those swords be tied to the demon speed achievement?

[ViviTheDragoness]

I've noticed there is a set of keys you can find (like a key chain) in a safe or a random spot in the penthouse (don't know where my boyfriend found it the second time). What is that exactly used for?

[VooDoo]

@gameplayer3050 thanks a lot, your addition is very useful and i think might help somebody so much

[gameplayer3050]

First of all, a quick thank you for the guide, it served as the basic for the TMS guide.
Second, there are a few things that are missing. THe KC can spawn in three spots. The one you did not mention was the small table in the living room with the two civies.
Second, an ECM rush is NOT possible unless you already used the KC. Using an ECM deactivates the input for the kc, meaning that ECm rushing is only possible once you opened up the two gold shelfs.
Third, and although this was is a personal one, the easiest way to complete this Heist is by creating a safe room in the office/sleeping room by taking out the guard there. 50/50 that you get a fire alarm there which means that you can just wait out everything while also being close to the meeting room AND while also being in a spot that has a gold shelf in 2/3 cases.
Fourth, but that depends on the skill level, I found it the easiest if I took 2ecm, 1 bb case as main assets.
