Fortnite Chapter 3: Where to Get Impulse Grenades and How They Work

gamerant.com:

Fortnite is always trying to keep things fresh. Beyond the fairly brisk pace of its seasons, which bring about drastic changes themselves, the free-to-play title regularly rolls out updates in between, altering everything from POIs to NPCs, quest lines, weapons, and more. Fortnite's most recent update unvaults the long-dormant Impulse Grenades, which some may need a refresher on as to how they work exactly.

First introduced in the second-ever season of Fortnite, the Impulse Grenade is a throwable item that launches players and vehicles caught in its blast radius. The item functions similarly to the popular Shockwave Grenade item, except that they do not negate fall damage and (at least the last time they were unvaulted) do not affect friendly players.

As of August 12, Fortnite has officially unvaulted the Impulse Grenade, which can now be found on the island. Impulse Grenades are part of the common loot pool, meaning they can be found in Chests, Supply Drops, and on the ground.

As mentioned before, Impulse Grenades are used to launch players or vehicles in virtually any direction. Like Shockwave Grenades, Impulse Grenades do not cause damage, making them more of a tactical item than an actual weapon.

Detonating quickly upon landing, skilled players can utilize Impulse Grenades to get some seriously devastating eliminations.

Categorized as a Rare item, players shouldn't have too much difficulty tracking some Impulse Grenades down and can stack up to nine in a single item slot.

While Impulse Grenades may be the only item unvaulted, it isn't the only thing making a return. Fortnite's UFOs have reappeared on the island, finally giving Chapter 3, Season 3, a flying vehicle. Also
