Doctor Slone has a solid plan in order to deal with the alien invasion in Fortnite Season 7. The countermeasure device is all set to send the aliens back to where they came from.

However, it still needs to be activated. And that's exactly where we loopers come in. As if Doctor Slone would ever get her hands dirty!

In order to get the device to work, we'll have to first find three alien devices, and then insert them into the Countermeasure device to get it to work.

But where do we find these alien devices?

Where to collect three alien devices in Fortnite?

These alien devices in question look like purple orbs. And surprisingly enough, you'll find them at alien biomes only.

Not all alien biomes have them though. There are three specific biomes where you'll find these devices. That being said, here are the locations.

  • The first alien device can be found at Scenic Spot, towards the north of Corny Complex.
  • The second device is in an alien patch towards the east of the Aftermath.
  • The final device is also towards the east of the Aftermath, but you need to travel a bit farther to the gas station. It'll be inside a few bushes.

Once you've managed to get your hands on these devices, all you need to do is head inside the I.O. base at Corny Complex and make your way to the Countermeasure device. Once you've made it here, interact with the device and you're all done!

Although it's some work, this Fortnite weekly challenge is worth the 30,000 XP. Have fun!
