Agatha Christie - The ABC Murders (Xbox One)

Achievement may glitch!
Apparently this achievement can glitch sometimes. If you failed to unlock it, try deleting your save file and re-doing all the observations. This should unlock the achievement, while re-using a preexisting save does not work. (thanks to Celestis and to oneEyEstang22 confirming this)

Hints:
Every obsveration counts, afaik. That means the ones where you simply click to investigate plus those where you have to use the to focus on things (+ controller vibrating).

Every observation counts. Environmental and people.

There are some which can be easily missed. As far as I remember, a few of the more far fetched ones were:
- At the first crime scene (Andover) just right at the beginning there is a store on the left which you have to examine.
- At the second murder site, you can observe the beach by going all the way to the right on the main street. You can also observe the café where some of the witnesses are (all the way on the left) before entering.
- Insinde the mansion (the first time you're there and also after interviewing the sick old lady) there are a lot of shelves and cupboards that can be "observed". Often you have to do this before triggering the main event because afterwards this isn't possible anymore. When you're inside the living room for the first time and Hastings is keeping watch, the trigger event is solving the puzzle of the left shelf (assigning the chinese symbols) in the back. So try investigating everything else before solving this puzzle.

My last advice is:
Try investigating EVERYTHING and absolutely everything before you continue on ingame. Most of the time, you cannot investigate/observe some things after triggering some main story event. So before you try solving the case try clicking on everything possible in that particular spot where you find yourself in. There are not a lot of options here and I had absolutely no problem getting this achievement (whilst not even trying) in my first playthrough.

There is an excellent guide from Gamepressure which has marked every observations. You can find it here: http://guides.gamepressure.com/agathachristietheabcmurders/
(thanks to oneEyEstang22 for the tip)

If you missed it, the game saves your progress for every achievement (it is cumulative over multiple playthroughs - you don't have to do all this in one). It will unlock in every other playthrough as soon as you have investigated all there is. :)

Good luck!

Before I get into the details of how to unlock this achievement, there is something you need to understand. THIS ACHIEVEMENT IS GLITCHED. If you trigger the glitch, the only way to get rid of the glitch is by completely deleting your Save Data. FifthBloodHell has confirmed that trying to bypass the glitch by playing on a different in-game Save Slot will not work.

I don't know exactly what triggers the glitch, but it seems like if you don't make all the observations in your first playthrough, the achievement will not unlock, even if you meet the requirements in later playthroughs. I can confirm that you can back out to the game menu on your first playthrough and it won't trigger the glitch. I can't confirm if closing the game triggers the glitch. Once again, if anyone tests this, please PM me the results and I will update my guide.

To delete your Save Data, you need to get to the "Manage" menu for the game and go to "Saved Data".
Once there, select your save file and select "Delete Everywhere". If you just select "Delete From Console" or the "Delete All" option from the previous menu, it will delete the save data from your console, but it will not delete the save data from the Cloud. So when you boot up the game again, it will upload your save data that's still glitched. You'll know if you deleted it correctly if you start going through a new game and the "Help" menus pop up and the in-game achievements unlock once you meet their requirements like they did the first time you played the game. (Not the achievements adjacent to your Gamertag.)



ALRIGHT, so what are Observations?

Observations are essentially the Mini-Game that you play that involves you having a white circle that you move around a scene and/or person to investigate three points of interest. You'll know if you started an Observation Mini-Game because the word "Observation" will be on the screen when you start it. The circle you move will turn greener/smaller and your controller will vibrate more the closer the circle is to the point of interest. You have to hold the circle over the point of interest for around 2 seconds for it to be considered Observed. Once you've "Observed" all three points of interest, the Observation is complete. You'll know if you found them all/did it correctly if the marker shows 3/3 and the Mini-Game ends.

The points of interest that you will be searching/observing, in general to progress through the game, are not required to unlock the achievement.




There are around 35 Observations. Most will be done through normal story progression, but there are at least 10 missable observations, possibly 14 in total. Once again, if anyone tests the possibly missable observations, please PM me and I will update my guide.
