Fortnite’s patch v4.3 content update is here and it introduces a new item: the Bouncer trap.

This new Fortnite Battle Royale item is really a combination of two old items: the vertical and horizontal jump pads that used to be in the game. Now, instead of two different pads, the new Bouncer trap will bounce you in different directions depending on how you hit the pad. If you use it on a wall, you’ll bounce to the side, on the floor you’ll bounce up and if you run into with quite a bit of speed — like say, with a shopping cart — it will send you flying forward.
