Does knockback
— In-Game Description

The Alien Knockgun Launcher is an Explosive Weapon in Fortnite: Battle Royale. It was introduced in Chapter 2: Season 7.


The Alien Knockgun Launcher shoots a fast-moving electric ball projectile. It explodes on impact, knocking back opponents within a certain radius. This renders them temporarily stunned. If the player knocks themselves back with the Alien Knockgun Launcher, they do not get stunned, allowing for a "blast jump" that launches the player much further than a standard jump.


An Alien Knockgun Launcher is given to all players during the Experiment, along with an Alien Jetpack.


The Alien Knockgun Launcher doesn’t use any ammo.
