I also can’t get this achievement. I got all the achievements except this one. ]:<
Maybe this has something to do with backrooms at the Albain level?

i was wondering the same! ive been trying to wander around it as much as i can but no luck yet ;-;

I was thinking that maybe it had something to do with the PartyPoopers, like the backrooms anomaly. Buuuut the description for the achievement just says "no humans allowed, sorry." That might be a subtle hint? Idk

omg! thank you!

so you have to be really patient and wait until the wall with northbound and southbound arrows (anomaly version, it should be near your exit point) will fully slide backwards, opening up a tunnel where you get the achievement!
