We really need to know what the exact, extremely specific requirements are to unlock these achievements. I just finally unlocked Shadow, but I didn't get Ghost even though I killed nobody. So I got Shadow but not Ghost? Want to hear the best part? I got Clean Hands at the same time. An achievement that has given me nothing but grief and had me playing through the game without even subduing a single guard or killing (or eating!) a single rat. Shadow + Clean Hands, but NOT Ghost?!

I love this game but these achievements are [censored] killing me.

Can we unlock these achievements by replaying single missions that need the attention? Are there weird little rules about things we can't do (like "no killing rats allowed! Don't kick that can in front of that Survivor!") or something?

Low Chaos
What caught me out with Chaos was the fact that the end of mission screen calls it “Chaos (current total)”. I got ‘High’ after my first mission, and since it’s a total, I thought it was already too late to ever get ‘Low’, so I didn’t try to avoid killing after that.

It’s not. If you get High Chaos on the first mission but then don’t kill many people on the next few, it’ll go back to Low. In other words, redemption is possible.

But it’s still not that easy to get Low Chaos. Here’s what Bethesda say about how it’s calculated and what it means:

Chaos is a value that is adjusted according to the actions of your character during gameplay. This system is a hidden mechanic and you will only see the Chaos rating displayed during the ‘end mission’ Stats screen.

The basic rule is killing less than 20% of the characters in a Mission should allow the Low Chaos rating to be sustained.

Your character’s Chaos level will change the story outcome and lead to other various differences throughout gameplay, such as more enemy characters, more rats, or different scenes/environment items and conversations.

Kills by Rewired traps will contribute to player kill amounts and Chaos; that’s Watchtowers, Arc Pylons, and Wall of Lights.

Rats, Hagfish and River Krust do not raise Chaos if killed. They also do not count towards detection of your character.

Wolfhound kills do not count towards Chaos, but they can detect your character. Wolfhounds can discover bodies, and their corpses will count towards “bodies found”.

Weepers do count for detection. They do raise the Chaos level if they are killed.

The best method for regaining a Low Chaos rating is to not kill enemy characters and take stealth routes to avoid combat when playing through a mission.

There are scenarios where performing a good deed will drop the Chaos rating by a small amount (Example: saving a character that is in distress).

Following “Non-lethal” objectives will decrease chaos by a significant amount when the mission is completed.


No kills
Not hiding bodies well enough after choking them out or sleep darting them can sometimes lead to other characters finding them or may lead to nearby rats cleaning them up, counting as a kill towards your character’s stats.

Unconscious characters won’t survive a fall from a great height, or a slip into the water which will also result in a kill towards your character stats.


Ghost
All characters and creatures count as detecting the player character, with the exception of friendly characters, Rats, River Krust, Hagfish and Watchtowers. This is evidenced by the red bolt icons upon detection.

Friendly characters will turn into a detection if they see your character do anything aggressive/hostile (kill someone, be hostile towards the NPC, carry a dead/subdued body, etc.). They will gain the red bolts when this happens.



that is copy and pasted from a pc gamer article. with information they got directly from bethesda. for some reason I cant post links or I'd just give you a direct link

Yes, I think most of us here are familiar with that article. What it DOESN'T cover is how some actions, or glitches, negate Clean Hands and/or Ghost,
and there are conflicting reports regarding whether they DO or DON'T. For example,
So some official confirmation on these special situations wouldn't hurt.

I'm in the same boat. I got shadow, but not Ghost or Clean Hands. Even though at the end of each mission I got both boxes marked for undetected and no kills. The other trophies for not killing/detecting at certain parts (like the missions up to the bridge) were received as well.

Perhaps body detection also secretly goes into the score? Or like above some glitch. Hopefully they'll release some more information.


*edit* well I just replayed the mission with granny again and stole the key and escaped without detection (with help from time stop a few times) Still didn't unlock.
