@Arun1000 I was going for bad ending 3. Everything on that ending and after in the guide only worked with picking "help yanux."

Which achievement are you struggling to get?

After bad ending 1. I had to switch to playthrough 1. No matter what I did on the scout the area route, I died. I tried all the options.

Bro ending three is terrible XD (Got it first run before using this guide, I like to play VNs blind for the first go) But damn it all! I was not expecting a bad ending for opening the door.

Ty too ! Well, it was how I wrote it - don´t know what happened there, but I swear that I told the truth. It´s weird, yes - but the main thing is: in the end we have 100%, and your guide is fine.
Game on, bro :)

I can confirm my method for [Bad ending 3] does work so I don't understand how you didn't get it from choosing "Scout the area" instead of "Help Yanxu" at the start because the only important decision for that path is "Find Eleven." I've added back the missing choice for Yanxu's ending and the "Entered the side story" achievement has been placed in chronological order in relation to the others. I appreciate you using my guide and noticing these errors, Thank you.

Np, 3 am xD

I'll review it all in the morning and sort it out. 2am rn

Bad ending 3 doesn´t work with "Scout the area". I did the 2. playthrough with "Help Yanxu" instead and got it.
And after Bad ending 5 and "load" I missed the choice "open the door", which I did and got Yanxus ending.
Side story: Could not find this after 1. playthrough, like you said.

I found the side story achievement after completing all endings so it may or may not be there after the first playthrough.
