In The Quarry for the trophy Blood Pact you must get every character infected in a single playthrough. This means they must get bitten by a monster to suffer an infection.
Only the playable characters count for this: Jacob, Nick, Ryan, Dylan, Max, Kaitlyn, Emma, Abigail, Laura. The Hackett family members don’t count. If characters die AFTER they have been infected that is fine and doesn’t void the trophy. However, it is best to keep them alive and thus combine this playthrough with getting your missing Collectibles. It’s recommended you follow the Everyone Survives Walkthrough & Everyone Dies Walkthrough first. If you followed those Walkthroughs the only collectible category remaining are clues. Particularly, the two clues in Chapter 2 that require going to Shady Glade: Hackett History Clue #2 & Hackett History Clue #3. These were mutually exclusive with the Rocky Road path. If you already found all clues from Prologue & Chapter 1 you can start replaying from Chapter 2 onward to save time. No need to start a completely new game. Remember that Chapter Select resets your Collectible Progress to what you had at the start of the Chapter. You must recollect all Clues from Chapter 2 onward (everything from Chapters 2-10 must be picked up again). Then your collectible trophy will unlock in Chapter 10. Refer to The Quarry Collectible Guide along the way to pick up all missing items. Try to keep all characters alive as long as possible so that you can find Collectibles with them. Make the same choices as you did in the Everyone Survives playthrough to keep them alive, except for the choices listed below to get them infected.

Everyone Infected Walkthrough
- Max & Laura are automatically infected, you don’t need to do anything to get them infected. Don’t worry about these two, there’s no way to mess anything up with them.
- Chapter 1 (Preparation for Dylan Infection) – When Abi & Emma are talking at the locked cabin, they must choose to “BREAK IN”. This is mandatory so that the monster attacks Dylan in the Chapter 5 Radio Hut to infect his hand. If you didn’t break into the locked cabin in Chapter 1 then the monster will focus on the locked cabin and not attack Dylan at all. If you followed the Everyone Survives Walkthrough you will already have done this.
- Chapter 2 (Shady Glade path for missing clues) – If you followed the Everyone Survives Walkthrough you should’ve gone to Rocky Road on the previous playthrough and gotten all Tarots. You should only have all clues left. For your everyone infected run start replaying from Chapter 2 and go to SHADY GLADE and grab the two clues “Hackett History Clue #2 & Hackett History Clue #3”. Remember to pick up all other clues from Chapters 2-10 as well, everything must be recollected to get the trophy for all clues in Chapter 10. Follow the The Quarry Collectible Guide along the way.
- Optional – Chapter 2 (*Preparation for Butterpops Trophy) – As Nick during shooting contest against Jacob: Nick shoots left melon > shoots same melon again after cutscene where he walks closer to it > shoot 2 bottles on the far left > shoot 1 bottle on the left. This doesn’t impact infections, it’s just preparation for the Butterpops trophy in the next playthrough (don’t need to replay Chapter 2 then).
- Chapter 3 (Nick & Abi) – After Abigail & Nick get attacked by a monster in the woods, Nick gets automatically bitten and infected. To infect Abi, when she runs away choose HELP NICK > QTE:
> RUN > Smash 
/ 
> DON’T “Climb Tree” (DON’T press / – let timer run out) > Abi will hide behind rocks instead > FAIL THE HOLD BREATH EVENT (results in Abi being bitten in the throat and gets infected) - Optional – Chapter 3 (*Preparation for Butterpops Trophy) – As Ryan running in the woods choose to take the 2 SHORTCUTS so that you’re quick enough to see Bobby dragging away Nick. Then choose “SHOUT” > SHOOT and hit Bobby (muscular hunter guy). This doesn’t impact infections, it’s just preparation for the Butterpops trophy in the next playthrough (don’t need to replay Chapter 3 then).
- Chapter 3 (Preparation for Jacob Infection) – At the end of Chapter 3 you will play as Jacob and get trapped in the woods by a hunter’s trap. After the hunter cuts you loose, THROW DIRT (Press ). This makes it so the Hunter won’t smear blood in Jacob’s face. Then in Chapter 6 he can get infected, see Chapter 6 point below.
- Chapter 4 (Emma) – On the Chapter 4 island while playing as Emma, when you enter the tree house upstairs choose the following QTE: SEARCH BAG > USE TASER > TAKE PHOTO >
> smash on zipline > SPRAY > > > BLOCK DOOR > USE TRAPDOOR > > FAIL QTE (DON’T PRESS when trying to push the cabinet) > Emma’s Arm gets bitten > 
(Emma tasers the monster) > FAIL QTE (DON’T PRESS ) > Emma’s Leg gets bitten > > Emma escapes through the hatch but was bitten in her arm and leg. See the video guide. - Chapter 5 (Dylan) – See the Chapter 1 choice – if you broke into the locked cabin in Chapter 1, then Dylan automatically gets his hand bitten in the Chapter 5 Radio Hut. After his hand gets bitten choose “TERRIFIED” (not “Desperate”). It’s important you DON’T cut off his hand so that the infection spreads.
- Chapter 6 (Jacob) – At the start of the chapter after walking around as Jacob, you will get a cutscene where Jacob and Emma reunite (if Emma is still alive). Jacob then gets attacked by a monster, FAIL THE FIRST QTE (DON’T press ). The monster will jump on top of Jacob and bites him in the throat, but it doesn’t kill him. Next choose RUN > Smash while running > PRY OPEN. Jacob will be infected from the non-lethal bite.
- Chapter 6 (Nick) – In Pool House Nick automatically turns into a monster.
- Chapter 6 (Emma) – When playing as Emma where you start at the campfire/tents, walk uphill (doesn’t matter if you take left or right path). You’ll get a cutscene with the 2 hunters catching a monster. Choose “RUN”. Then another monster jumps out from the woods and bites Emma in the leg, but doesn’t kill her. This gives you a 2nd chance to get Emma infected if you missed the Chapter 4 opportunity. Just for good measure get her bitten here in Chapter 6 even if she was already bitten in Chapter 4 (she survives even if she was bitten before). This may be optional but better to be safe
- Chapter 8 (Optional) – Because you infected Emma she will have turned into a monster in the car parked outside the lodge. If you want both Abi & Emma to survive: when the group opens the car to find Monster Emma choose SHOOT > SHOOT MONSTER EMMA BEFORE SHE KILLS ABI > SHOOT MONSTER EMMA ON CAR ROOF > REGULAR SHOT. This is what I did on the playthrough when I got the trophy, but it shouldn’t be needed for trophy purposes. It’s easy to miss shooting the monster when it runs quickly towards Abi, best to back up your save as soon as the “Shoot” choice comes up. If Abi dies it shouldn’t matter, just continue with the last remaining infections.
- Chapter 9 (Ryan) – When Ryan is bleeding out and Laura talks to him and offers to bite him, you must choose to be bitten to get infected by her. Choose: SYMPATHETIC “It’s not your fault…” > ACCEPT > Interrupt Event: DON’T Pull Away (DON’T press / )
- Chapter 9 (Kaitlyn) – At the scrapyard after going to the yellow crane, during the cutscene where Dylan controls the crane, choose SLAM THE CAR > FAIL THE QTE (DON’T press / .) –> TROPHY UNLOCKS IMMEDIATELY DURING THIS CUTSCENE AFTER FAILING THE QTE! You don’t need to finish the story for it to pop.
If you did everything correctly you should have the trophy as soon as Kaitlyn is bitten. Continue to Chapter 10 to collect your last clues, that should take care of the last collectible trophy. For anything else you have left refer to The Quarry Trophy Guide & Roadmap.
Can you have characters die if they are already infected and still get the trophy?
That’s a good question. Personally, when I did it I kept everyone alive as I wanted to pair it with Collectibles.
I currently have some friends testing it with having some characters die. I *think* it should be fine if they die after infection but needs additional confirmation.
Already infected characters CAN die. I got Abi killed by Monster Emma and still got the trophy when I got Kaitlyn infected.
Thanks for confirming! 🙂
Hello can we infect Kaitlyn in chapter 9 even if she received blood on her face in chapter 5 against Bobby? Because on your clues guide you will be told that you have to miss the QTE and then shoot him when he has the table in his hands to retrieve the clue at the chalet in chapter 10.
You can still get her infected in Chapter 9 yes. That’s how I did it myself. In my case she got blooded in CH5 by Bobby, then got infected in CH9 and I got the Everyone Infected trophy. It doesn’t matter. She wipes off the blood by the time you reach Chapter 9.
Anyone know if it’s possible to have Wolf Emma kill Abi and still able to kill Wolf Emma afterwards?
No, during the death of abi by werewolf Emma, Kaitlyn and Dylan would see it as a opportunity and would just skedaddle
So I’m following the guide to the letter, and Jacob did not get infected where supposed to. Emma kicked off the Werewolf before Jacob was bitten
Did you do the “THROW DIRT” in Chapter 3? If not, Jacob gets blooded and the monster wouldn’t attack him because of that.
I’ve trying to both infect and save everyone in my new playthrough, but in order to save Emma at the end when she meets up with Jacob, you had to pick up her silver bracelet in the parking lot during Chapter 1 so that he throws it off and she can use it to save herself from werewolf Jacob after he transforms. I didn’t see it in this guide or the everyone survives guide, I feel like it should be, otherwise Emma will die (you will still get the Blood Pact trophy however)
You absolutely rock for these guides bro. Took me 5 playthroughs to platinum. After my 3rd playthrough I was mind numbingly bored. 1st playthrough blind with my decisions, 2nd/3rd everyone lives/dies, 4th infected/collectables, 5th peanut butter pop. Just saw I somehow have Until Dawn in my library so hoping it’s platinum isn’t so painful.
This game is so frustrating! I had all of them infected but at the end, it obviously didn’t count Abi’s infection and I don’t know why?! I failed the hold breath event, I saw her get bitten but at the end of chapter 10 it classed her as alive, not infected?!!!
Ignore me, trophy must have popped silently as I didn’t see it but I checked my trophies and it’s there despite saying Abi was alive? Very confusing!
Same. Trophy popped as soon as I infected Kayt, but somehow Abi was listed as alive. Must be some bug.
Also did not understand the purpose of the broken ring on the ladder…
Just got the platinum after this Infect Everyone playthrough. I am confirming that you CAN complete this playthrough with the Peanut Butter Butterpops! trophy. I used Auto-aim. I did not cut off Dylan’s hand. Everyone lived at the end. Make sure not to release Jacob from the cell or he will kill his summer fling.
Actually, he can live if he collects Emma’s bracelet all the way back in chapter one, to the right off the car
but in the part where he says that you have to kill jacob for the peanut butterpop trophy, does it void the everyone infected trophy?
Do all possible gun encounters need to happen (get triggered) or is it possible to get the trophy if some of them get skiped and only availabe encounters are successful?
I think if a character dies any combat encounter they may have had in chapters beyond the point they died get cancelled out without voiding the Trophy so, yes, I think you can do that.
Why doesn’t Abi turn if she gets infected? Only plausible explanation is that she gets bit by Kaylee and not Caleb. Otherwise she should of changed around the same time as Nick.
I think since she gets bitten later into the night she doesn’t have time to turn
How do you get Emma to transform in the basement and not in the car?
Instead of her being bitten in the treehouse, she will need to be bitten on the second opportunity, therefore she has more time before she transforms ( if she gets bitten both times, she will be found as a werewolf in the car)
For the part where BOBBY is dragging NICK (chapter 3), make sure you actually shoot Bobby successfully! I thought I did, but I checked my PATHS, and it showed I missed!
If you missed, the scene will show Bobby kneel down, walk away a bit, then use his pistol to shoot off one of his fingers (I have no idea what this means, but it happened in my first run ever of this game!).
If you were successful, Bobby will drop Nick and sulk back into the shadows (no pistol shooting off finger scene). I think that’s what happened, I forget… but always, always, always check PATHS tab in pause menu.
Finally got the platinum, took a long time, and was painful going through the same scenes over and over.
****SPOILERS BELOW***
Assistance for the peanut butter butterpops trophy below as well.
This guide is very good, thank you so much, the only issue I had, which seems to be shared with other players is the peanut butter butterpops trophy, the only way I got this to work was to start a whole new game, and pretty much set everything to auto, especially the combat. I then played the game however I wanted, I didn’t, I repeat, DIDN’T shoot Jacob in the bushes and I DIDN’T shoot the roof or Dylan’s hand off, and I got Emma killed early on. I even made totally different choices and missed some QTE on purpose, for example the one where Laura runs after killing (or not killing) Constance she wakes up in a totally different part of the house.
The only important points is that you must shoot Bobby when he tries to take away Nick (taking two shortcuts) and you must shoot Bobby again as Kaitlyn when he hold the table. The game does this automatically. (As you are MEANT to shoot)
If the game wants you to shoot, it will shoot automatically. I also killed Ryan by removing the knife so i didn’t have to play the final section with Silas. (He still shoots Chris Hackett the werewolf), just dies after.
So, new game, set everything to auto, play as you want aside from the two points above. And it should pop.
Aside from that, great guide. Just wish you could skip the dialogue, would save hours!
Game deleted, moving on….finally.
For those having issues with infecting Abi, make sure you fail twice in order to get her infected:
Abigail does not make a choice to run or hide + Abigail fails to hold her breath.
