Here is my 100% Achievement Guide for Afterparty!
This is an easy one to get, at the beginning of the game, after you find out your in hell and you walk outside for the first time.. You are able to press
. You see the map, but if you scroll to the left using the
button, you are now on Bicker (Hells Social Media).
Simply stay on this screen for 20 minutes and it unlocks. (Make sure to keep your controller on too and do not let it die)
Go to 12:50 in the video to see how to get it and where.
Hope this helps.
