Aliens will be the primary theme throughout the rest of this Fortnite season. Not only are they predominant in the Battle Pass but they're also slowly taking over the Battle Royal island, or so it seems.

The lore has really taken a turn lately. Doctor Slone has been giving players orders to investigate IO Guards. Just last week, as part of week eight's missions, players had to hack into IO Operative's computers to find out if there were any moles as she thought. Hacking them gave her some mole suspects, which she then had to investigate further.

This week it seems that there may be more trouble coming Doctor Slone's way but, this time around, it's trouble with Aliens. There are several Alien Billboards around the map with subliminal messages it seems. It is your job to help her and the IO (Imagined Order).

Detector And Alien Billboard Locations

Detectors and Alien Billboards are scattered throughout all of the island. You can find them primarily in the main POIs, particularly areas with a large number of houses and buildings. You need to equip a detector and disable an Alien Billboard in the same match, you only need to do this once. You can find them at Craggy Cliffs, Pleasant Park, Believer Beach, Boney Burbs, Retail Row, Lazy Lake, Catty Corner, and Misty Meadows.

If you want to know exactly where to find them, one of the most well-known content creators in the community, Reddit user u/thesquatingdog, has created this map with all locations of both Detectors and Alien Billboards.

How To Equip Detector And Disable An Alien Billboard

Once you've found a detector, the next step is equipping it on your back so you can disable the Alien Billboard with it. To do this, approach the black glowing case and press and hold the 'Equip Alien Signal Detector' button.

The detector will then appear on your character's back. Unfortunately, it will not beep or show you when the signal is stronger if you're getting closer to the billboard. You have to find it on your own. The detector only allows you to see the true meaning behind the Alien Billboard once you're close enough to it.

When you spot the Alien Billboard, approach it. You will notice that the ad on it from far away turns into a message that says 'SUBMIT'. You can see this subliminal message thanks to the detector that you're carrying. Press and hold 'Disable Subliminal Message' and it will disappear.

Once you've done this, the detector will also disappear from your back and the billboard will be back to normal. Doctor Slone will be very thankful. The point of this mission was not only to stop subliminal messages from being spread but also so Doctor Slone and the IO could reverse engineer the technology and understand how it works.
