* As you make your way through [[DeathTrap the Gauntlet]] to get into Nuka-World, you can encounter a room filled with deactivated machine gun turrets, with a CymbalBangingMonkey sitting in the centre. If you are smart enough to [[ProperlyParanoid destroy the monkey]] before it can activate, turning on the turrets, RedEye, narrating the player's progress over a tannoy, will grumble about the latest 'Vic' "hating fun".

* Private Kowalski is standing guard over a memorial to the NCR soldiers who died in the Battle of Hoover Dam, a group that includes his brother. [[https://www.youtube.com/watch?v=MxJPRn1r4Ks If you fire your gun at the monument,]] [[BerserkButton Kowalski will become angry with you]], giving you a chance to placate him with a Speech check, blow him off or insult his brother, the latter of which will cause him to attack.

* You can find Clanden's snuff films and present them to Marie Pappas, the head officer of the NCR Embassy's military police, which makes sense but it doesn't present itself as an option to you. This is because it actually is a legitimate option in the games files, but one of Cachino's dialogues is bugged and doesn't set the required objective correctly, which locks out the option to tell Marie Pappas the identity of the man in the tapes.

* [[SnakeOilSalesman Griffon]] wears a wig to make all the other ghouls in Underworld believe that his "Aqua Cura" can heal them like he says. Wearing a wig of your own grants a special dialogue option to point out your matching haircuts, which Griffon will try to dismiss it as a coincidence.

* The most common ways of entering the Brotherhood of Steel's bunker in Hidden Valley is through Veronica's quest, lockpicking the door, or finding the password on one of the dead Paladins out in the world. However, if by some chance the player has completed the Enclave Remnant's quest and learns how to use power armor, you can fool the guards at the intercom into thinking your one of the Paladin's sent out if you have the password and Brotherhood of Steel power armor on. Major characters inside will know it's a trick, but the fact this exists in a specific order, stands out.

** Related to this; normally players are told to go to Nipton by NCR Ranger Ghost at the Mojave Outpost. If they already have been to Nipton when they speak to her, she'll request you scout it out, but your dialogue changes a bit and you tell her you've already been to Nipton, thus allowing you to save time. If you haven't gone yet, most players wind up running into Vulpes, but you can complete the quest without meeting him if you instead talk to Boxcars, who is hiding in the general store. Talking to him is treated as finding out what happens, so you can choose to talk to him and avoid the Legion entirely.

* Beginning the Gomorrah questline requires you to talk to the receptionist about Cachino. Later on, you need to find a way into his room. You can just speak with the receptionist again and ask for the key, but the game doesn't present her as an option.

* If you follow the recommended path of the main questline you will likely finish the sidequest "Come Fly with Me" in the REPCONN Test Site before you even talk to Veronica, who can only be encountered in the 188 Trading Post, a place a fair bit ahead. However, if for some reason you recruit Veronica before doing that quest and bring her along with you, she will have unique dialogue for it, comparing Jason Bright with her old mentor, Elijah. This dialog even counts as one of the triggers needed to start her companion quest.

Say dialog even counts as one of the triggers needed to start her companion quest.

* Sturges, a pretty major character in the Minutemen questline as [[TheSmartGuy their resident tech expert]], is a Synth. This is never remarked on in game, and he's not killable, so normally you wouldn't find out. Players only discovered he was one by turning off his essential status using the console and finding he drops a synth component upon death.

* Completing the post-ending quest "In Sheep's Clothing" ([[spoiler:in which Mayor [=McDonough=] is exposed as a Synth agent for the Institute]]) before getting Hancock's affinity with you to the halfway point will alter his heart-to-heart with you, expressing his frustration with whether his hatred for the central character of said quest was rightful, misguided, or even had any point at all.

* During "Curtain Call" when you meet the Institute Courser atop the skyscraper, he initiates dialogue with you when you get close, and he waits by the door of the room and comes toward you when you enter, so it's likely you'll talk to him instantly, and he initiates combat when the conversation ends. But if you get into the room without initiating conversation, you can hack the terminal in the room to open the door the Courser was interrogating the Gunners about. He has dialogue to thank you for doing so and will excuse himself to head into the room and initiates a recall code on the captive Synth inside, before he deals with you.

* If you meet Mrs. Wright, she would detect you being a tribal and proceed to [[TranslationByVolume speak more slowly and loudly]], which you can immediately rebuff by telling her you're neither deaf nor stupid. If you have a pulse rifle or are wearing power armor, your character will ask her why a tribal would be walking around with those things.

** Big Jesus Mordino has a weak heart (similar to Cassidy) and will die from receiving any stimulant you might be carrying (including [[WeaksauceWeakness ''Nuka Cola'']]). Fitting end for a drug kingpin.
** Mr Salvatore can be murdered by pickpocketing the air tank from his breathing apparatus, leaving him suffocating helplessly. Alternatively, you can replace it with a poison tank. Fittingly, he orchestrated the death of Richard Wright with a canister of poisoned Jet.

* In a mission given to you by The King, you have to investigate a bodyguard named Orris who seems to be doing his job a little too well. He does this by paying thugs to play dead while he fires blanks, giving the illusion of skill. If you decide to go back and attack the thugs on the ground, they get up, yell "Orris 'aint payin' us enough for this!" and attempt to kill you.

* Spending too much time exploring or walking around Pre-War Sanctuary Hills when the Great War starts and the game will trigger a NonStandardGameOver, as the bombs will drop and kill you instantly.

This is never remarked on in game, and he's not killable, so normally you wouldn't find out. Players only discovered he was one by turning off his essential status using the console.

* Almost all of Mr. House's dialogue has a corresponding line from Yes Man. If you kill House and install Yes Man into the mainframe before going after the Platinum Chip, it will be Yes Man that greets you inside the Securitron Vault. He will also give the demonstration on what the Mark II upgrade does in House's stead. Alternatively, if you pursue the independent ending without upgrading the Securitron army, he will scold the Courier (as best he can anyway, given his programming) for trying to take on Caesar's Legion and the NCR without a standing army.

* Nick Valentine has a case file on the Mysterious Stranger in his office. If the Stranger appears when you use VATS and kills someone, he will comment on his apperance.

[[AC:VideoGame/Fallout76]]

* In ''Old World Blues'', a required quest involves you entering a chamber containing Gabe, the cybernetic dog of Doctor Borous while he was still human. Gabe is hostile and immediately attacks you. You'll almost certainly be forced to kill him, but you're not required to, and even if you dig up the item you need from one of a dozen dirt piles around the chamber, roboscorpions will attack and almost certainly kill Gabe if you didn't. But if you did avoid killing Gabe ''and'' protected him from the roboscorpions (neither of which the game even really hints is possible), Doctor Borous has unique lines thanking you for sparing his dog when you bring Gabe's bowl back to him.

* During "The House Always Wins", the player is required to kill the Brotherhood of Steel. If the player somehow manages to get the BoS allied with the NCR (normally impossible, as it can only occur during a portion of the NCR main quest that takes place after killing House), the player can inform House of this, and House even has unique dialogue concerning it—mocking the Courier's decision by pointing out that giving the NCR a powerful ally just puts House’s own plans in jeopardy, and he sends you back out to kill the Brotherhood.

* During the quest "Emogene Takes a Lover", you need to deal with a cult called the Pillars of the Community to negotiate for her release. It's possible to meet them before receiving the quest, and if you kill them, they'll respawn for the quest, and their leader will have a different name from before to establish this is a new group of the same name. This also lets you intimidate him into letting Emogene go by pointing out you killed the last guy running this kind of scam.
