How to collect an IO access card from an IO Guard in Fortnite
To collect an access card from an IO Guard in Fortnite, you need to kill an IO Guard and the best place to do this is Corny Complex. Not just knock them down - kill.
On this farm you can find a number of IO Guards wandering about the house and inside the barn. Since this area is full of loot, you'll be able to easily find a weapon and a shield potion before hunting down an IO Guard.
If, however, you're having trouble finding said guard, then you should head to the IO bunker hidden beneath the farm, which is filled with IO Guards just waiting to be murdered.
You can enter the bunker by using the stairs in the barn, but the sneakier way is to use the porta-pottie located in the house to teleport yourself in the bunker. The room you find yourself in will provide you with a small amount of cover as you fight the nearest guard.
Remember - you have to completely kill the IO Guard, so continue shooting them once you've knocked them down. Upon the guard's death, they'll drop an access card, so run forward and collect it!
With this challenge completed, you'll now be able to complete the next quest - plant wiretaps in different key locations.
