Old IO servers locations in Fortnite explained

Before you can properly start this Fortnite challenge, you must establish a Device Uplink at one of three locations around the Command Cavern.

After, or before, doing so we recommend gathering some supplies and weapons, because for this challenge you’ll be venturing into the enemy filled Command Cavern.

There are three old IO servers located in the Command Cavern, but you only need to visit one to complete this challenge.

The easiest old IO server can be found by diving into the vent located west of the northern entrance to the Command Cavern.

Jump down this vent to find the IO server.

Simply jump into the vent and land on the platform below to find the server waiting for you.

This server can also be reached by exploring the western side of the Command Cavern, past one of the drills, and going through the door on the ground level of this area.

Head through this doorway to find the old IO server via the Command Cavern.

To find the second old IO server enter the Command Cavern from the northern entrance and go into the ground floor of the central building. Here, in the area beneath the stairs, you’ll find the IO server.

The final old IO server is the hardest to find, but, if you want to visit it, start by exploring the tunnel directly opposite the northern entrance to the Command Cavern.

Head to the top-left corner of this tunnel area to find a set of locked double doors. Thankfully, there is a nearby vent which you can head into.

After crawling through the vents for a bit, you’ll find yourself in the room behind the locked doors and there, on the ground floor, you’ll find the old IO servers.
