It’s that time of year again Fortnite fans, the time to monitor vibrations on the ground! Fornite Seismographs are one of the quests that we got from the Ghostbusters: Afterlife collaboration and we’ll need to install seismographs in 3 out of 6 possible locations.
So we’ll be hunting for what looks to be blue outlines around the viable areas. All you have to do is interact with said outlines to deploy the seismographs.
Catty Corner and Misty Meadows are the areas that we can deploy them at and each of them has three possible placements. You don’t need to go to the next area if you’ve already deployed three in one area unless that’s just your thing.
