Activating the Countermeasure Device in Fortnite is pretty easy; the problem, however, is that it’s located in the IO base beneath Corny Complex. It means you’ll have to either fight, avoid or run past some powerful NPCs to complete this challenge.

It’s a good idea to stock up shield potions, health restores, and grabs a good weapon or two before heading into the IO base so that you can defend yourself against both the NPCs and any other players.

You can enter the IO base by either using the stairs in the central barn, going through the door located in the cliffside near said barn, or using the porta-potties located in the Corny Complex farmhouse–­­­.


Once you go inside the base, you need to head to the room in the bottom left-hand corner on the lowest floor. Here you’ll find the Countermeasure Device and, to complete the challenge, all you have to do is interact with it.

It is for your information that new legendary quests will be introduced every Wednesday and are time-bounded.
