Fortnite has reintroduced Bouncers with the v10.40 update that happened on September 25th which has led to players using Bouncers in a creative way.
A major component of Fortnite has always been who has the best skills in building and editing. Having a slight edge could be the difference between a glorious Battle Royale victory or a disappointing loss.
The reintroduction of the Bouncer has created a new way players can easily get through enemy walls. A Reddit user has discovered that by placing a Bouncer right outside a wall and underneath a ramp, then jumping onto the Bouncer while swinging your pickaxe, you will easily break into your opponents wall.
This is something that will take a bit of practice to perfect, but could be extremely beneficial trick to use in the game.
Keep in mind that Bouncers are a pretty rare find and only come in stacks of three. You will also need some space and protection from a team mate.
There is no telling how long this will remain in the game, but enjoy it while it lasts!
