Achievements don't unlock in Atomic Heart?

The fact is that you must have used some type of mod, so the game will not give you any achievements, try to reinstall the game if the problem persists.

Try to re-install it again

Hello

There can be cloud sync issues occasionally and achievements can be delayed. I know a person that got one 7 weeks after the fact. Unfortunately you just gotta wait for it to appear. I've also had a few show up without the notification popping up so be sure
to check and see if it's shown up periodically.

I have had something similar check your internet if its playing up it might be taking longer than it should. Or you have unlocked multiple achievements at one time.

As conquistas estao demorando um pouco a contablizar , devido alguns problemas , as vezes ela nao ta aparecendo a notificacao.
