By holding down the crouch button while running, you’ll start to slide (think Apex Legends).
This tip is also applicable to out running the Storm. It can be hard to get beyond it’s reach once caught inside if there are no vehicles around. Thankfully, Fortnite Chapter 3, Season 1 implemented a new Slide mechanic. By holding down the crouch button while running, you’ll start to slide (think Apex Legends). If you do this while going downhill, you’ll vastly increase your movement speed. Use this when trying to escape rivals and the pesky Storm.
