All sacrifice achievements working 100%

[SiKiTtOyA]

I just did all sacrifice achievements now with only 1 friend. I used the tap button A trick for local server. It worked for all.

For chaos generator i signed in with a local controller. So there was me, my friend and my 2nd controller. Cleared out some zombies and activated all 3 generators at the same time. The achievement popped up right away.

hope this helps with anyone who is still stuck getting these.

Good Luck!

they're not working for me.
i had to offline all of them, and i'm still working on getting the generators started at the same time offline.
kinda hard with only 2 controllers

You're lucky they worked for you, I like the poster above am having trouble with the generator achievement, and it just freezes when I tap A.
