In this guide, we show you how to collect Alien Devices, then activate the Countermeasure Device beneath the Corny Complex in FortniteAlien Devices are required to retaliate against the extraterrestrial intruders by activating the Countermeasure Device beneath the Corny Complex.
Although it’s unclear exactly what this machinery concealed in a subterranean bunker performs, it’s surely a significant step toward recovering control of the Fortnite island as the season draws to a close.
We don’t often see missions with several steps to complete in one sitting, so make sure you’re ready with our guide to all of the Fortnite Alien Devices locations and how to use the Countermeasure Device beneath Corny Complex once you have them.
Fortnite Alien Devices locations
To begin this task, you must first acquire three Fortnite Alien Devices, which appear as floating purple balls and can be difficult to find due to their ability to blend in with their environment.
They’re all around the fringes of Corny Complex, which is convenient because that’s where you’ll end up once you’ve found them, and these are the particular locations where you may collect the Fortnite Alien Devices:
- Northwest of Corny Complex, at the bottom of the purple clearing
- In the purple clearing southwest of Corny Complex, near a bush
- In the purple clearing south of Corny Complex, under a tree
How to activate the Countermeasure Device in Fortnite
After you’ve gathered the three Fortnite Alien Devices, go beneath Corny Complex and activate the Countermeasure Device.
This is located beneath the large red barn in the centre of the farm, and there are various ways to enter it; however, for the sake of this quest, the electronic entrance cut into the rock face on the east side of the barn is the most convenient.
From that door, turn left and follow the corridor to the southwest room, where you’ll find the Countermeasure Device, which you can interact with to finish the task.
Be aware that this underground base is defended by Fortnite IO Guards as well as Doctor Slone herself, so try to sprint across the area and trigger the Countermeasure Device without engaging in a lengthy firefight.
