While the delayed jetpack is still without a release date for Fortnite: Battle Royale, developer Epic Games has now announced a new item coming to the popular multiplayer shooter. Remote explosives are coming to Battle Royale "soon," Epic said on Twitter. You can see what they look like in the image below.

As in other games, remote explosives in Battle Royale will allow players to place a charge and then detonate it from a distance. This will add a further element of strategy to the battle royale game, as you can wipe out opponents from afar if you execute it effectively.
