Prey

Thanks for the info !!!

So, if I understand this right, if you get the Do No Harm achievement, you'll get this achievement too.

@Cpt Obvious1994 I thiiiink so, but technically I am not so sure that NOT saving somebody is the same as killing somebody, so I don't know if you could technically earn that achievement without earning this one. I'll be interested to see what others say after more time

Hey Aggro Graf, can I use this table in my achievement guide over at XboxAchievements.com?

@NShepherd N7 - Absolutely! I basically just copied information from the strategy guide and added a few bits, so it would be hypocritical of me to say 'no' haha

Thanks bud, cheers!

@Aggro Graf.

You can get "Do No Harm" so long as you do not personally kill any humans yourself, not saving a human or a mind-controlled human exploding by itself will not count against you(also Phantoms with names do not count).

Just a minor note: this achievement unlocks after the credits, when you are being evaluated by Alex Yu and all those "characters" you have interacted with in the game. It does NOT unlock together with the "no gunman killed" achievement

Not sure why I didn't get this, the only bad things I did were left Ingram to die and didn't get Luther glass. I completed all the rest and it didn't pop during the eval at the end. :(

To confirm, you won't lose any empathy if you kill January?

Im near the end. Saved Doctor Igwe, Sarah Elazar, Mikhaila Ilyushin, Alex Yu, done the Gustav Leitner quest, and Incapacitated Dahl. I think I've also saved Aaron Igram but I'm not sure. Apparently for Mind without limits, you need to kill January?

Killing January does not void this achievement... I bashed him when appropriate and still got the achievement.. It may be a -1, but will not void it for sure.

Prey's an amazing game..but boy is it buggy (cheevos and quests alike)...i did the same as: DGC Valent. aside from "Help Luther Glass Completed" i didn't get to his body in time...but no way did i NOT get the points required from my initial playthrough. Not sure if i will try it out again after seeing there's problems with finding people as well...

Great. 1 human accidentally killed (no idea where, just randomly showed up on the counter) everyone else saved and didn't get it. Love glitched achievements ruining game experiences for me. Ridiculous.

Seem somewhat buggy. Did a playthrough where I did every single thing on the list above, empathy quotient was "exceptionally high" but no achievement. Finally got it on a playthrough where I made sure I never met the cook, seems like killing him was voiding my achievement, even though a lot of people say killing him doesn't count.

Tried twice to get this ach. I did everything the guide said but not no ach. Killed just one human, the guy in the trauma center under mind control. Surely killing just him isn't enough to void it? Does it matter what choice u make at the end, ie using the nullwave transmitter or the keys? Also at the very end after the credits does it matter if take Alexs hand?

Spoilers

Just got this on my first playthrough without really knowing about it. I did most of the side missions and saved/spared everyone I could. I saved most of the brainwashed people, some I couldn't reach or died after I knocked them out, but I also earned the "No harm" ach too.

I took Alex's hand as well, all the characters at the end said they thought I should live. The only negative was not killing the imposter cook (found Mikhalias father and let her listen to it as well)

Can you install Typhon Neuromods and still get this? I’ve installed Minic Matter. And can you finish the cooks quest without killing him?

just an FYI doesn't pop until the end of the credits, as your playthrough is being discussed.

Wouldn't it just be best to optain this when doign the "Do No harm" achievement? Since it is a run where you have to save every human, im guessing ones empathy will be a perfect. And then SLAM! 2 birds, 1 stone.

dont kill the cook i did all the above except killing the cook and the achievement did not pop

So i have finished this achievement along with no needle runs its simple save the following people
SPOILER
Save Aaron Ingram
Save Dr. Igwe
Save Sarah Elazar
Save Mikhaila Ilyushin
Save Alex
and save mind control people found at beginning at crew with electric shock gun (cook area is not neccesary)

I just got this in a run along with Do No Harm in NG+. I skipped much of the cook's sidequest by hacking the turret in the kitchen, then hacking the door to the freezer while it was still locked. He panicked and ran, the turrent ID'd him as hostile and killed him for me without it counting as murder in my stats.

@Batarang76 No killing the Cook at all? Even if you just disarm his charge and laughs himself to death?

I let the cook die by his recycler charge and still got this (also got the no kills achievement with it). I didn't know you could disarm it. Maybe that counts as a kill because you intervened whereas all I did was walk in and walk back out.

I'll come bk guide once got first run out way

According to the guide I should have got this. Although the end game stats showed 1 human dead which was early in the game I think I accidentally killed the guy locked up in isolation in the Trauma centre.... anyway no achievement.

Despite that...it's a great game, but I think I will end up 1 or 2 cheevos short of 100% after my other play through... Next play through is only Typon powers so it's appropriate to KILL ALL HUMANS!!

@machinegryphon even if you disarm it he will suddenly die so there's no use

I did all of the empathic choices listed above, with the exception of killing the cook. I did however make sure to advance that particular quest line until the point where Danielle asks you to kill him on the bridge. The achievement unlocked midway through the final cutscene just after Danielle finishes speaking to you.

@eloteassassin13 I literally thought 20 mins ago when playing 'he sounds like Walton Goggins' (always Shane Vendrell to me). Came in to read this guide and you've confirmed that! Thanks and lol

I made a last minute choice to go back to the crew quarters cafeteria to kill the cook. I had only tazed him earlier. My idea was to complete Danielle's side quest for +points towards the good ending.

The cook thus became the only human killed by me, as per the stats page.

During the final evaluation cutscene Danielle no-sold the whole side quest based on "unclear motivations"... Riight... And despite saving the mind controlled humans she voted no. Thus, no achievement!

I re-loaded my backup from before cafeteria detour and went straight to Alex to get the nullwave schematics. Danielle's quest therefore failed as incomplete, and later according to her I never encountered the impostor. But more importantly, she ultimatel voted yes and I got the achievement.

TL;DR Don't kill the cook! And don't trust the +/-1 math!

I'm almost certain it's the cook quest that voids this. I watched an ending of someone who did get the empathetic ending and the only difference was Danielle saying that I had a drive for retribution vs. a low drive in the ending that did get it. I didn't even kill the cook myself, I disarmed his trap and he bled out and I still didn't get it. I was credited with one human killed but I think that was a mind-controlled case, I still got the voiceline about going out of it's way to avoid harming humans however.

I got this achievement on my second play-trough and I think that the game is partly unclear about the requirements for it unlocking. I tried unlocking this on my first play-trough but no luck. The weird thing is that by calculating the points in this guide, I would have gotten more points the first time I played trough the game..

What I did different between play-troughs:
- 1st time I completed a lot if not all side quests in the game, I unlocked all collectable achievements.
- I completed all the quests pointed in this guide.
- According to my data I accidentally killed 1 human, I do not know who but I am sure that it was no one detailed in this guide.
- On the final cutscene, all characters who speak to you were positive about me.

- 2nd time I only did the main quest-line and just a few side missions.
- I saved Aaron Ingram.
- I saved Dr. Igwe and did the Leitner side quest.
- I saved Sarah Elazar.
- I saved Mikhaila Ilyushin and completed her side quest by showing the audio file to her so she would learn the real truth about what happened to her father.
- I saved Alex Yu.
- I did not kill a single Human in the game. I did kill humans that transformed into Typhon. I did not kill mind controlled humans.
- I did not do the Danielle Sho / Cook quest-line. Make note that I never ventured to the cafeteria area in the game so I never met the cook in the first place. This might be a key element because me not meeting the cook at all was mentioned in the final evaluation so this way I wasn't able to know that I had to kill him.
- I did render Dahl unconscious. After shooting him, I did not repair the broken part for cargo bay during the ultimatum quest, however I used the part from Psychotronics thinking no one would be killed. This does end up killing Aaron Ingram, however it does not count as a human killed in your data. When I returned to Psychotronics during the final quest I checked his location and he was in fact dead though. After the game I got a mention of this as well during evaluation. Specifically, what was said was that I did not let him live but that the evaluators wanted to let me live despite Aarons fate. Right after that sentence the achievement popped.
- I did not remove the Neuromod from Dahl.
- I did not complete the Escape attempt. Keep note that I never knew about this quest in the game on this play-trough.
- I did not help Luther Glass. Again, I had no knowledge about this quest either in my quest log.
- I did not save any mind controlled humans.

The second run was a no human kills / no Neuromods run btw. This might shed some light on this rather glitchy achievement.
