The problem with both achievement guides is they are not completely in order. It's all mostly random with just descriptions of how to get them with no screenshots and a guide, outlining the exact spot. If the achievements were in order, you wouldn't have spoilers and probably receive more awards and likes.

These woods, although not open world, have multiple paths. It can be confusing about how far you went unless you save and it shows what chapter you are on. Like, did I miss something in the last chapter? I don't know because the achievement guide is not in order.

Monsters can be bypassed without killing. You need to use a camcorder, not a flashlight. If you don't get close to them, they will not attack. On a level with the train, you need to collect parts on foot.
The code from the bunker will be sent to your phone while listening to the radio in a police car.

also theres no way to get past any of the monsters without killing them

how do you get the bunker code?

Beat the game 4 times, but didn't get the "Last goodbye" achievement. The third time I went to the achievement "Pacifist" trying to fulfill the conditions for achieving with Bullet. At the end, the dog growled and walked away. I found a video of how someone goes through a game and at the end he gets the achievement "Last goodbye". I did everything the same ... The dog ran away, the achievement did not fall ... I already broke my head, what am I doing wrong. Maybe someone can share saves?

if you didn't collect too many, you should be fine, but if it's more than maybe 5 or so not sure, then you sadly would need to do another run if you want to get the "Break the cycle" ending :/
Triumph through, you got this!

Ohh... Seems like i have to make the game 3 times

Yes, you need to avoid the totems and the dolls (except the last 3 dolls which you have to collect to progress through the game, you will know which ones).

Is it for sure that u have to skip the dolls as well as totems?(

K.I.A is inn chapter 11
