Go to Ticonderoga Safehouse

Talk to Desdemona at the Railroad HQ. Glory has discovered an Institute Courser presence near the Ticonderoga Safehouse, which has since gone dark. Desdemona tasks you with eliminating the Courser threat to ensure the safety of the faction. Travel to Ticonderoga Safehouse, just south of Monsignor Plaza in Cambridge.

Kill All Coursers

When you get to Ticonderoga Safehouse, it seems you have arrived a bit too late to save the other Railroad members. Your task now is to eliminate the Courser threat to secure the area.

Enter the building and ride the elevator to the next level, where you will be met by one of the Institute Coursers. Speak with him to find out what they’re doing there. There are a couple dialogue options that allow for persuasion, if you wish to glean a bit more information regarding their orders.

Enough with the idle chitchat. Eliminate all of the Coursers, as well as any hostile synths you find throughout the safehouse. Watch out for a few machine gun turrets as you traverse the building. Be sure to kill the main Courser leader, X9-27, as well as the remaining hostile Institute Coursers outside the safehouse. Thoroughly loot the area, then report back to the Railroad HQ.

Report Back to Desdemona

Once the safehouse is secured and free of Coursers, fast-travel back to the Railroad HQ at the Old North Church. Inform Desdemona of the status of Ticonderoga Safehouse. She’s not happy about the news, but still rewards your efforts with a hefty 500 Bottlecaps, and a new weapon. Not bad for a day’s work.

Make sure to complete the Railroad Quest: Underground Undercover before moving on to the next quest Precipice of War . For more Fallout 4 features and tips, head over to USGamer’s

In this article we will look at the walkthrough of Fallout 4, provided that main character joined the Podzemka organization. The passage of Fallout 4 is not linear, so situations are possible when some quests for the Underground begin during the passage of the main plot of the game.

For convenience, use summary :

From the very beginning of completing quests for the underground, the player may have the feeling that pacifists are gathered in the underground; they, of course, enter into confrontation with the Institute, but do not carry out planned forceful actions against it, but simply kidnap synths and give them new life. But in fact, the Underground is a sleeping beast and is by no means a hamster, you just need to touch the Underground and the answer will be cruel! Both the leadership of the Institute and the leadership of the Brotherhood of Steel will find out this the hard way; these organizations will be completely destroyed by the Underground, but first things first.

Quest #1: “Dear Freedom”

This quest must be completed to get to the Underground headquarters. Without a hint from outside, you will have to rack your brains to find them. Let’s not bore you, in this quest we simply follow the markers found, the final goal of the journey is Old Northern Church. From this Church you can get into the catacombs, in which the entrance to the Subway headquarters is located, but that’s not all, to open the door you need to enter a password, turning the disk so that the mark points to a certain letter.

Password to the Subway headquarters: RAILROAD

Quest #2: “Undercover work”

In fact, this is the first quest that the main character completes as an agent of the Underground. And immediately he is given a difficult task: he needs to penetrate the former Underground base and pick up the necessary items from there. It seems from the description that there is nothing complicated, but as always there is one “but”. This old base has been uncovered by Institute agents, so there may still be an ambush there, so you will need to be careful.

So it turns out, the base will be full of synths, but you will not be alone, your partner in this quest will be the Deacon.

Quest #3: “Boston at Night”

Once you become comfortable as an Underground agent, you will be given more interesting tasks, one of these is the quest “Boston at Night”. During this quest, your character will take part in transporting an escaped synth to Ticonderoga Station. This quest is not particularly difficult, you will have to run and shoot a lot, but it will not cause you any special difficulties.

Quest #4: “Underground and undercover”

This quest can be started only after the main character has visited the Institute, teleporting there from the teleporter built in his settlement. Desdemona will ask the main character to find the agent they introduced into the Institute with the call sign Patriot. This quest quite large, during which the main character will have to run around the Institute, around the Cambridge Polymer location and face many difficulties.

Quest #5: “Operation Ticonderoga”

Having completed the next quest, we return to Desdemona, she will tell the main character that one of the Subway's safe houses, the so-called Ticonderoga station, does not go to mandatory communication sessions and is generally completely silent, there are two options, either their transmitter has failed, or The Institute found out about this station and it was captured or destroyed. Your task, as an agent of the Underground, is to get to the Ticonderoga station and figure out what happened.

The task is clear, let's get started. Having reached the station, your character will be convinced that the station has been captured by the Institute, and apparently they have already begun to get tired of the Underground, because they sent several very strong synth hunters to the station. Therefore, before moving to the station, collect more ammunition, first aid kits and chemicals, in case they come in handy. Having dealt with the synths, we return to the Underground headquarters and “delight” Desdemona with the news.

Quest #6: “On the brink of war”

This quest is very interesting and dynamic, it will put the Underground and the Brotherhood of Steel on the brink of war, but what about the brink, it will be a real war, to the credit of the Underground, they did not start this war. We can say that the quest “On the Brink of War” is a mirror reflection of the quest for the Brotherhood of Steel “Strategic Thinking”, in that quest the brotherhood, together with the main character, destroys the entire leadership of the Underground at their headquarters, in the same quest you are on the side of the Underground and repel this attack .

Having completed the previous quest, the main character reported this to Desdemona and after they talked, the Brotherhood of Steel attack on the Underground headquarters begins, our heroes repulse this attack and, seething with anger, decide to carry out a quick counterattack before the enemy recovers from a crushing defeat. To do this, they clear the brotherhood’s stronghold, which is located in the Cambridge police station, and steal a helicopter from its roof.

Dressed as a brotherhood soldier, you fly on a rotorcraft towards Prydwen to destroy him and the Brotherhood of Steel.

Quest #7: “Red Flash of Missiles”

This quest begins after technician Tom was able to hack the protection of the rotorcraft and you took it into the air. Your task is to get to the Brotherhood of Steel airship Prydwen and place three powerful explosive charges on board it. It just seems that everything is so simple, but you will be confronted by well-equipped and armed soldiers of the brotherhood, so you will have to work hard.

Locations to explore:

• Charlestown
• Bunker Hill
• Cambridge
• Ticonderoga

Give Carrington the prototype

One of the Underground agents, Old Man Stockton, needs help with a runaway synth, H2-22. All information about the problem must be taken from the Underground cache. A cache is a mailbox with a special sign that agents use as a means of communication. And don’t forget about your call sign, without which they won’t deal with you.

Beware of super mutants that you may meet along the way. However, your main opponent is the raiders, who need to be killed in order for the synth transfer to take place.

Wait until night falls

Wait until 23:00 for Stockton and Synth H2-22 to arrive. The old man will give you the synth, and he will light the kerosene lamp as a signal that everything is clear and leave.

Now an Underground agent must come to pick up the synth in safe place. While you wait, you can try to talk to the not talkative H2, who for some reason does not want to talk about the Institute.

Charisma

Apply Gift of Persuasion to H2-22 (level - medium).

Wait for the Subway contact

The contact's name is Hi-Rise, you can ask him for the password to make sure it's yours.

He needs to deliver the synth to Ticonderoga Station, and for this, High-Rise still needs your help, since the raiders are “sitting on their tail.”

Follow High-Rise

You'll head roughly south towards the raider camp at Monsignor Plaza. If you have not cleared this location yet, then beware of shelling by raiders and turrets. Deal with the enemies, and from there make the final push to Ticonderoga.

Talk to High-Rise
