Where to complete the Cleanse Tanks and Escape hidden Gnome challenges in Fortnite Chapter 2 Season 4

Pesky Gnome.


That pesky robotic Gnome is back in Fortnite, and he is up to no good. There are two new secret missions located very close together after today’s update, so some easy XP can be made if you visit Slurpy Swamp.

The first challenge, Cleanse Tanks, requires you to head to the ground floor of the main Slupry Swamp building that has the two large tanks on the floor. The two tanks are usually covered up, but you will notice the tops are missing. If you jump in the tanks, you will find the Slurp appears to have been poisoned somehow. To fix it, all you need to do is stand in each tank for a couple of seconds, earning an easy 10,000 XP for your Battle Pass.

The second hidden quest is quite close to this spot, so you don’t need to travel far at all to finish it up. If you look around the room you will notice a broken wall. Just inside the room is the robotic Gnome. If you walk up to him he will fire some rockets and make a speedy escape, so it looks like we won’t be getting justice today.

We don’t know why the Gnome was trying to poison the Slurp, but it has been an ongoing saga ever since he tried to fake his own assassination at the GNOM Talk, and he has been up to nothing but mischief ever since. He will almost certainly be back and seems to have a serious grudge against Slurp for some reason.
