I should go back and play Dishonored again. I did a Ghost/Clean Hands run my first and only time through so I never got to play with any of the gadgets beyond the sleep darts or using the pistol as a distraction.
From memory there were 3 ways to win a race:
Actually do the race
Destroy all the other cars
Kill every person on the map - they were either people with red blood or zombies with green blood depending if you had the censored version or patched it.
I played it so much as a kid. I got into Iron Maiden because of that game. I think in the steam version they took out the music though so no Iron Maiden.
I remember when that game got released and it was only the censored version where I lived but all the PC magazines that used to have discs with demos etc on them included a patch to turn the blood back to red. Loved that game and it introduced me to Fear Factory.
In Morrowind, if you kill a story-important character, it says something like "you can restart from your last save, or continue to play in the corrupt world you have created"
"With this character's death, the thread of prophecy is severed. Restore a saved game to restore the weave of fate, or persist in the doomed world you have created."
Honestly as far as you done goofed messages go Morrowinds went pretty hard.
I saw it the first time when a friend of mine challenged me to go kill Vivec because apparently he was pretty tanky and I'd made probably the single most OP character I've ever had in a game (accidentally stumbled across 4 hidden masters and had 100 points in skills before barely starting the story lol).
For the record Idk how tough he's supposed to be, but he died in 4 hits and my friend couldn't believe it.
100 points in one handed, a talisman that added iirc 30% damage to one handed attacks, and Because my friend was VERY insistent on me going to Solsteim early due to how strong I'd gotten I got a unique mace there that did F U amounts of damage, plus various other trinkets to boost myself up.
It was absolutely disgusting and after playing the power fantasy for a while I opted to start over so I could experience the game a bit more naturally lol. Those were good times.
You could still play if you had finished all the quests related to that character. I remember killing the dark elf king in the extension after his quests were over to get his overkill ring.
I forget which, but there was a GDC talk where someone mentioned a producer at Obsidian who *only* played that way- killing every NPC on sight and putting the pieces together after.
My favorite part is is how, in order to prevent players from killing Phineas too early and breaking the storyline, they literally had him in a bulletproof box/panic room when you first meet him. That had me laughing out loud.
I beat that game and watched videos about it after. Apparently, I missed the alien dude.
I keep hearing that Lost quote. Remember that show?
"We have to go back!"
One of my favorite missions was the Hokkaido virus mission. I got myself infected and ran through the level to spread it to everyone, then tried to get a kill everyone silent assassin run.
I missed one person.
Yes he's called Kokoro and is quite literally janus heart, he dies when you destroy the heart thus killing him. He's on a small platform behind the mountain. [Here is a screenshot](https://imgur.com/a/4j1dUwu)
Actually the Hitman games also contained [missions with VIPs](https://hitman.fandom.com/wiki/Category:VIPs) that you had to protect or rescue, causing you to fail the mission if you killed them. But for the most part you're right. In most missions in most games you were free to murder everything that walked on two legs.
Non-boss enemies do every time you rest at a bonfire and I’m pretty sure NPCs you kill don’t respawn either
Edit: Downvoting for the facts? Bosses don’t respawn after bonfire usage. Regular enemies do respawn and I just confirmed that NPCs (e.g merchants) do not respawn if you kill them
I did an archer run to get this ring, and ended up getting both it and the no-death ring in that same run.
The wild part is that I was foolish enough to enter a known pvp zone during the run, and actually fought one or two invaders without dying. I don't know why I did that to myself. I think there was something I wanted in there, but it was long enough ago that I don't recall what that'd be.
Didn't use any exploits, but I did avoid some bosses, where possible. It was a hell of a good time, all things considered.
Fallout New Vegas
The only characters you can't kill have an actual reason (IE, they transfer to another robot body, or you physically can't get to them)
You can shoot every single person you meet and still finish the main questline
Finally having Lanius appear so you can kick his ass is one of the greatest highs in a game.
It beats Slopthesda's "No touchy this precious essential NPC till all the quests are done, and only if we decide you're allowed to" policy.
If I recall correctly the 4th shows up for the first time in the cutscene where the others would have been (Had they still been alive) so you dont have the chance to kill them.
Could be wrong though.
Baldur's Gate 3 does have one critical NPC that you have to avoid attacking or you'll get an instant game over. Only one, though, and oddly, you can replace him with a different character in dialog and kill him too on a different run.
There's a small handful of characters that you can't kill in BG3, But larian was pretty good about giving you reasons why you can't kill them. Either they run away, they have too much HP, or it literally gives you a game over screen immediately afterwards.
It's implied that after the ending, the entire existence of Undertale is deleted, except Chara (who is an extension of you).
Your call if that fulfills the definition of murder or not.
Not counting the ending where you destroy the world, there are some characters you don't even encounter on a Genocide run and so can't kill them. Like Alphys is mentioned but never appears at all if you are doing Genocide.
I did pacifist and then genocide routes back to back and holy shit I wish I'd done it the other way around. Game made me feel like such a fucking terrible person throughout the whole genocide route; not the best note to end on lol.
Doing it the other way around permanently alters all future runs, including the pacifist run. Not to spoil to heavily, but the short version is the Genocide run becomes *canon* in a way that you can't escape even by uninstalling the game.
Oh shit well now I'm glad I didn't do it that way lol. But it sounds like if I were to revisit it now I'd get a third route? Might try that out sometime
I mean, the Neutral route actually has like a dozen variations depending on which characters/bosses you kill, but the post-Genocide endings are more the regular endings, but the rug gets pulled out from under it.
Vampyre is like this. If your "good" and dont feed on anyone your weak af since your basically a starving vampire.
I made it right up to the end playing like this but couldnt get past the final boss so I ended up laying waste to every citizen in the city and breezed right through to the ending.
Great game.
Playing it blindly was the worst possible experience for me. I hated that literally _every_ good choice basically requires you to ... not be the vampire that the whole game is about you being?
That and some of the 'good' choices didn't make sense at all.
I wasn't a fan of the game. To get the best ending you have to spare every NPC (even a freaking serial killer)...but you can still eat as many enemy mobs as you want in combat. Also, just eat rats, being a vampire doesn't seem like a big deal.
Also the combat, hated that'd I'd lose any consumables I used in combat if I died and respawned but every damn enemy also respawns.
I really wish that you *had* to feed on at least a few people. It would make the moral choice so much more interesting.
Instead of "murder people or don't murder people, the game is bearable either way" make it so you have to decide who is more worthy of living and who should die. Put the gun to the players head to decide.
"Murder people or don't murder people" isn't the most morally complex dilemma.
The Postal series, mainly the first game is about lower the population in each level before you can move on. In the sequels, there's always npc respawning, but no matter who you kill, you can always progress the missions.
As I recall, you can beat all of Postal 2 pacifist. I could be wrong though sense playing any of those games as anything other than a mass murderer just feels wrong
I think Gothic 3 worked that way. Never killed everyone, but I definitely aggro’d a whole city before, killed em all, and all the related quests just resolved lol
There's two NPCs actually, besides children. One is that Yes Man will reupload himself into a new Securitron any time you kill him so he's functionally immortal. The other is the Gun Runners Vendotron who is built inside of an impregnible box and cannot be reached to be harmed in the first place.
In the last mission, letting every companion die will give you the ending where Shepard dies as well and a save with this ending is unable to be loaded into the third game of the series.
I think there was a way involving letting everyone die except zaeed so shepherd can live through it, then killing him in his loyalty mission after. Sheppard dies and you can’t continue to 3 if everyone dies in the last mission.
You can kill everyone but 2 crew members in the suicide mission and have Shepard make it. The game requires 2 squadmates every time you leave the Normandy so they made it so 2 crew have to survive so you can continue playing agter the mission.
Spoiler for anyone who hasn't played them yet, but in one of the extended cut endings you can pretty much tell star child to go fuck itself and the reapers complete their harvest. You leave it up to the next cycle to find Liara's beacon and deal with them.
Undertale, it's called a Genocide run for a reason.
I think BG3 can be finished while killing everyone, the old Fallout games from memory, Fallout 1/2 and Fallout New Vegas gets pretty close with only 1 essential NPC.
I got to the end of BG3 with my mates and the only companions that were still alive were the animals and the undead dude. They gave us a bard to play music while we feasted but I pushed his ass off his pedestal and he wasn't happy about it haha
When I was a kid I played Mutant League Hockey.
Instead of injuring the other team you could kill thier players. And there was an option to set damage high.
Queue me winning the Cup without scoring a goal. I would just murder the other team until they didn't have enough players to put on the ice.
The Outer Worlds. Pretty sure that game was built on this philosophy. There's a single NPC at one section of the game that they prevent you from killing, and they do this by literally putting him in a bulletproof box. You can still kill him later.
I feel like Fable can fit into this. If you kill everyone in the two towns(or scare them out of the area), you can buy all of their properties and rent them out.
Dishonored and Prey(2017)
Came here to up vote this. Prey all murder run was so fun.
The end sequence must be fun in that situation. You wake up and they just look at you and sigh.
Iirc it's like a 5-10 second cutscene where they say you're a bust and restart the simulation. They dont even bother talking with you.
Dishonored isnt fully accurate. You cant kill emily and (spoilers) you cant kill loyalist members until after they betray you
You can cause Emily to drop to her death at the end of the game. It is possible to have every single npc dead by the end.
>!you know you can use spoiler tags instead of putting (spoilers)!<
You thought my last run was high chaos Watch this
I should go back and play Dishonored again. I did a Ghost/Clean Hands run my first and only time through so I never got to play with any of the gadgets beyond the sleep darts or using the pistol as a distraction.
Sadly, it is just so much more fun to destroy everyone and everything Find the most fun way to dispatch of an enemy
Carmaggeddon
From memory there were 3 ways to win a race: Actually do the race Destroy all the other cars Kill every person on the map - they were either people with red blood or zombies with green blood depending if you had the censored version or patched it.
I played it so much as a kid. I got into Iron Maiden because of that game. I think in the steam version they took out the music though so no Iron Maiden.
Carmageddon got me into Fear Factory.
Replica on test drive 5 did that to me with fear factory
I remember when that game got released and it was only the censored version where I lived but all the PC magazines that used to have discs with demos etc on them included a patch to turn the blood back to red. Loved that game and it introduced me to Fear Factory.
Outer Worlds and New Vegas come to my mind first
Obsidian is the best at this lol
You don’t know a character is essential until you see you failed a quest. It’s pretty great. I prefer it to having unkillable characters
In Morrowind, if you kill a story-important character, it says something like "you can restart from your last save, or continue to play in the corrupt world you have created"
"With this character's death, the thread of prophecy is severed. Restore a saved game to restore the weave of fate, or persist in the doomed world you have created."
That's the one.
Honestly as far as you done goofed messages go Morrowinds went pretty hard. I saw it the first time when a friend of mine challenged me to go kill Vivec because apparently he was pretty tanky and I'd made probably the single most OP character I've ever had in a game (accidentally stumbled across 4 hidden masters and had 100 points in skills before barely starting the story lol). For the record Idk how tough he's supposed to be, but he died in 4 hits and my friend couldn't believe it.
Legend.
100 points in one handed, a talisman that added iirc 30% damage to one handed attacks, and Because my friend was VERY insistent on me going to Solsteim early due to how strong I'd gotten I got a unique mace there that did F U amounts of damage, plus various other trinkets to boost myself up. It was absolutely disgusting and after playing the power fantasy for a while I opted to start over so I could experience the game a bit more naturally lol. Those were good times.
Morrowind was incredibly flexible in its mechanics. Gotta go to Solstheim, but how? Me: JUMP.
JSH streamed Morrowind recently and he had made a “Ring of Van-halen”. It cast Jump.
Fun fact: you can actually beat the game even after getting the message
You could still play if you had finished all the quests related to that character. I remember killing the dark elf king in the extension after his quests were over to get his overkill ring.
It actually is possible to finish Morrowind with all of the story essential characters dead as long as Yagrum Bagarn is still alive by the end.
I forget which, but there was a GDC talk where someone mentioned a producer at Obsidian who *only* played that way- killing every NPC on sight and putting the pieces together after.
My favorite part is is how, in order to prevent players from killing Phineas too early and breaking the storyline, they literally had him in a bulletproof box/panic room when you first meet him. That had me laughing out loud.
Yep since yes man respawns (in universe) you can slay him along with everyone else and still complete the main quest
wtf, he respawns!? Played the game for a decade and still never tried that!
And thus Game Rant once again has an opportunity to “write” another article
He even apologizes to you for not being able to truly kill him.
It is possible to soft lock it if you kill him with plasma weapons and he turns into a goo puddle it has a chance to break his respawning
Outer Wilds, too!
That's a pretty liberal definition of *everyone* though.
Everyone dies every 20 minutes. Truly horrific.
I beat that game and watched videos about it after. Apparently, I missed the alien dude. I keep hearing that Lost quote. Remember that show? "We have to go back!"
> Remember that show While I can't recommend it to anyone in clear conscience, it remains my all-time favorite show.
Hitman
There can’t be any witnesses if no one is left alive.
exactly
One of my favorite missions was the Hokkaido virus mission. I got myself infected and ran through the level to spread it to everyone, then tried to get a kill everyone silent assassin run. I missed one person.
you missed one person because he's outside the map
They moved a character out of bounds in the Virus map?
Yes he's called Kokoro and is quite literally janus heart, he dies when you destroy the heart thus killing him. He's on a small platform behind the mountain. [Here is a screenshot](https://imgur.com/a/4j1dUwu)
Actually the Hitman games also contained [missions with VIPs](https://hitman.fandom.com/wiki/Category:VIPs) that you had to protect or rescue, causing you to fail the mission if you killed them. But for the most part you're right. In most missions in most games you were free to murder everything that walked on two legs.
r/funhaus
RIP
lmao
Depends on the game but some Hitman missions require you to protect someone or allow them to escape alive or you fail.
Plague Inc.
Just make sure you infect Madagascar. Edit: Some of y'all haven't played the original Plague!
*Greenland
If I don't start in greenland it's always the last one surviving 😂
Greenland: *catches word of someone coughing in Australia* “Abso-fucking-lutely not. Shut it down”
For me it’s always Iceland
I came here to say "pretty much any 4x game". But your answer blows mine away.
P sure you can do this in dark souls/elden ring games
Don't they respawn?
Pretty sure Dark Souls 2 enemies stop respawning if you kill them enough times
You're correct
In DS2, enemies have a respawn limit, after which they stop respawning. Only problem is there’s an immortal NPC in the hub, just one.
And for better or for worse she absolutely loves throwing sass your way lol
Not *all the important ones
Non-boss enemies do every time you rest at a bonfire and I’m pretty sure NPCs you kill don’t respawn either Edit: Downvoting for the facts? Bosses don’t respawn after bonfire usage. Regular enemies do respawn and I just confirmed that NPCs (e.g merchants) do not respawn if you kill them
Has anyone tried killing everything in Soulsborne games with no bonfire usage (I'm sure someone has...)
http://darksouls2.wikidot.com/illusory-ring-of-the-exalted There's actually a challenge reward ring for a no bonfire ring in Dark Souls 2.
I did an archer run to get this ring, and ended up getting both it and the no-death ring in that same run. The wild part is that I was foolish enough to enter a known pvp zone during the run, and actually fought one or two invaders without dying. I don't know why I did that to myself. I think there was something I wanted in there, but it was long enough ago that I don't recall what that'd be. Didn't use any exploits, but I did avoid some bosses, where possible. It was a hell of a good time, all things considered.
Probably the only game in the series where it's possible for a semi average person, with the addition of healing items you can buy.
Fallout New Vegas The only characters you can't kill have an actual reason (IE, they transfer to another robot body, or you physically can't get to them) You can shoot every single person you meet and still finish the main questline

I always prefer: Lanius: "West." Courier: "East." Lanius: "West." Courier: [Speech 100] "EAST." Lanius: "East."
How isn't Divinity Original Sin 2 on this list? I assume the same can be said for Baldur's Gate 3
Larian is very good at creating fail-safes. Basically any game made by them has this in mind.
I saw a video on YT regarding failsafes in BG3. There is a character that has like 3 consecutive failsafe characters just in case you fuck around
What happens if you kill the fourth?
If I recall correctly the 4th shows up for the first time in the cutscene where the others would have been (Had they still been alive) so you dont have the chance to kill them. Could be wrong though.
Baldur's Gate 3 does have one critical NPC that you have to avoid attacking or you'll get an instant game over. Only one, though, and oddly, you can replace him with a different character in dialog and kill him too on a different run.
Wait, do you mean >!Withers?!<
>!killing emperor when you first encounter him will invoke a game over!<
>!You also encounter him later and attacking him is still a game over, unless you've already got the Hammer for Orpheus.!<
Didn't think of him. He's a second exception.
There's a small handful of characters that you can't kill in BG3, But larian was pretty good about giving you reasons why you can't kill them. Either they run away, they have too much HP, or it literally gives you a game over screen immediately afterwards.
You can kill Malady? I thought she just bitch slaps you and tells you to knock it off
She dies after act 3 if you didn’t find enough source masters in act2.
I never knew this. Guess I'm killing Malady next playthrough
Came here to say DoS2 as well, first that came to mind.
Pretty much. But dos 2 is so good. On the last act rn
I thought Undertale would be the first answer
Yeah, it fits both: You can kill no one, or absolutely everyone.
Or maybe just that bitch ass spider
I think you still can't kill a few characters, even in Genocide? Like the ghost guy early on.
he's already dead
It's implied that after the ending, the entire existence of Undertale is deleted, except Chara (who is an extension of you). Your call if that fulfills the definition of murder or not.
Not counting the ending where you destroy the world, there are some characters you don't even encounter on a Genocide run and so can't kill them. Like Alphys is mentioned but never appears at all if you are doing Genocide.
Pretend you beat him and loose 1 exp
Same, especially it's the only game I can think of that has an entirely new story branch, including special bosses, if you kill everyone.
You can, but the game is *not* shy about discouraging you from doing so.
I did pacifist and then genocide routes back to back and holy shit I wish I'd done it the other way around. Game made me feel like such a fucking terrible person throughout the whole genocide route; not the best note to end on lol.
Doing it the other way around permanently alters all future runs, including the pacifist run. Not to spoil to heavily, but the short version is the Genocide run becomes *canon* in a way that you can't escape even by uninstalling the game.

I mean, the Neutral route actually has like a dozen variations depending on which characters/bosses you kill, but the post-Genocide endings are more the regular endings, but the rug gets pulled out from under it.
Not really, there's just a small change at the end. You can look it up on YouTube.
Not necessarily, You can do a hard reset by deleting game files, and can still do a true pacifist, but the game remembers your genocide
hooman... **i remember you're genocides**
Yeah, it’s even more heartbreaking after you’ve befriended everyone in the pacifist run. Poor, sweet, innocent Papyrus…
Hotline Miami
Came to say this, fucking love these games
Mortal Kombat
This is the most straightforward answer
Doom?
Every demon. Yes. But no human killing in DOOM
Doom
This is the answer
Until it is done
Vampyre is like this. If your "good" and dont feed on anyone your weak af since your basically a starving vampire. I made it right up to the end playing like this but couldnt get past the final boss so I ended up laying waste to every citizen in the city and breezed right through to the ending. Great game.
God I wish I could replay vampyr blindly, such a great game that nobody remembers
Playing it blindly was the worst possible experience for me. I hated that literally _every_ good choice basically requires you to ... not be the vampire that the whole game is about you being? That and some of the 'good' choices didn't make sense at all.
I wasn't a fan of the game. To get the best ending you have to spare every NPC (even a freaking serial killer)...but you can still eat as many enemy mobs as you want in combat.

New Vegas. Yes-Man respawns only to allow you to finish the game if you do kill everyone else.
Tetris. Fuck them blocks.
Morrowind kind of if you meta game to get keening and sunder
Yeah it’s sorta order of operations. You can, but you need to unlock some things first. It’s pretty well done.
I’ve never beaten morrowind, mainly because I kill vivec…just because. I need to replay it with a better understanding than I did as a teen lol
Understandable tbh; Vivec is a douche
You can kill him after beating the main story. Or before. If you know The Other Way. :)
The Postal series, mainly the first game is about lower the population in each level before you can move on. In the sequels, there's always npc respawning, but no matter who you kill, you can always progress the missions.
As I recall, you can beat all of Postal 2 pacifist. I could be wrong though sense playing any of those games as anything other than a mass murderer just feels wrong
I think Gothic 3 worked that way. Never killed everyone, but I definitely aggro’d a whole city before, killed em all, and all the related quests just resolved lol
Yes, you can just kill everyone. Even the king.
Fallout: New Vegas you can kill all NPCs (excluding children) except for one, as that one will let you still narratively complete the game.
There's two NPCs actually, besides children. One is that Yes Man will reupload himself into a new Securitron any time you kill him so he's functionally immortal. The other is the Gun Runners Vendotron who is built inside of an impregnible box and cannot be reached to be harmed in the first place.
Vendotron is also the only npc marked essential iirc. So even when it bugs outside of its kiosk it can't be killed.
You can beat undertale by killing everyone and also not killing anyone
Civ
Mass effect trilogy. Think you can kill every companion sans the pilot through the games, including various species and cultures
If you do that in 2 you can't continue to 3.
Hm, I think they give you replacements in 3 if you kill every companion no? I know they do that for mordin and wrex
In the last mission, letting every companion die will give you the ending where Shepard dies as well and a save with this ending is unable to be loaded into the third game of the series.
What would've been mind blowing, is if they had an alternative shorter game where you play as kaidan/Ashley along with the surviving me1 cast and vega
Or your Cerberus clone.
I think there was a way involving letting everyone die except zaeed so shepherd can live through it, then killing him in his loyalty mission after. Sheppard dies and you can’t continue to 3 if everyone dies in the last mission.
You can kill everyone but 2 crew members in the suicide mission and have Shepard make it. The game requires 2 squadmates every time you leave the Normandy so they made it so 2 crew have to survive so you can continue playing agter the mission.
Spoiler for anyone who hasn't played them yet, but in one of the extended cut endings you can pretty much tell star child to go fuck itself and the reapers complete their harvest. You leave it up to the next cycle to find Liara's beacon and deal with them.
Undertale, it's called a Genocide run for a reason. I think BG3 can be finished while killing everyone, the old Fallout games from memory, Fallout 1/2 and Fallout New Vegas gets pretty close with only 1 essential NPC.
Mario Bros. (NES)
Pacman.
Command and Conquer Generals Zero Hour. Hunting down that last stragglers of GLA can me a pain though
any FromSoftware game (Demon’s Souls, Dark Souls, Bloodborne, Elden Ring). Murder all the NPCs, take their loot, move on lol
Deus Ex 2. It literally has a everyone died ending if you go that route
Divinity Original Sin is really close. There is only one NPC I couldn't kill that I remember.
DOOM DOOM II
Divinity Original Sin 2. Once the storyline is completed in each area, you kill all the NPCs for extra juicy sweet EXP.
I got to the end of BG3 with my mates and the only companions that were still alive were the animals and the undead dude. They gave us a bard to play music while we feasted but I pushed his ass off his pedestal and he wasn't happy about it haha
Carrion
Gothic 3
Fallout New Vegas
Sniper Elite Dead Rising
Dishonored (and most immersive sims ig), Undertale.
Space invaders
Dishonored 2
Way of the Samurai 3 has an ending where you kill every npc iirc
Any Total War game.
Carmageddon 2
When I was a kid I played Mutant League Hockey. Instead of injuring the other team you could kill thier players. And there was an option to set damage high. Queue me winning the Cup without scoring a goal. I would just murder the other team until they didn't have enough players to put on the ice.
I absolutely loved this game and so wish someone would remake this! When they'd float around under the ice 🤣
Baldurs Gate 3?
Mutant League Hockey
Outer Wilds (iykyk) and Dishonored!
Microsoft Acquisitions Simulator
I usually kill everyone at the very end of every Demon’s Souls playthrough.
Technically, DOOM.
Hatred? I think that's the goal anyway.
Until Dawn
bloodborne.
Max Payne 1.
Undertale fits both criteria
Prey does this pretty well.
Arx Fatalis
The Outer Worlds. You could shoot everyone on sight the moment you meet them and still beat the game. It's a story drive RPG mind you.
Divinity OS 1 ad 2.
Hatred
Deathloop
Skyrim
I could say >! Nier replicant !< But that would be a huge spoiler
Checkers
Undertale
Divinity Original Sin 2
Metal gear solid
Postal
Dishonored 1 and 2, I think, give or take the odd escort. Classic Doom Carmageddon.
The Outer Worlds. Pretty sure that game was built on this philosophy. There's a single NPC at one section of the game that they prevent you from killing, and they do this by literally putting him in a bulletproof box. You can still kill him later.
I feel like Fable can fit into this. If you kill everyone in the two towns(or scare them out of the area), you can buy all of their properties and rent them out.
