How do I get the 'Nightmare' achievements during the halloween event?

There are some achievements at the new Payday 2 halloween update and I was wondering how to get them. I mean these achievements:

There are:

  • First Nightmare
  • Second Nightmare
  • Third Nightmare
  • Fourth Nightmare
  • Fifth Nightmare

I randomly got the First nightmare, but I was wondering what to do to get these achievements?


need to get at least 3 baby masks on the upstairs after cracking the safe open. Each difficulty level gives you an achievement. Need to do all 4 of course to get all 4. Masks are in random spots. Sometimes grabbing one triggers a witch that will instant down you so u need to have support to get you up.


Just finish the level on every difficult and get all the baby's masks.
