Fortnite’s latest patch rolled out today (a little later than expected) and added new features to the Battle Royale and Save the World components of the game.

Epic Games released the 3.3 update for Fortnite this morning, bringing with it the previously announced remote explosive weapon to Battle Royale. You’ll find those rare C4 bombs in Fortnite: Battle Royale’s Supply Llamas, treasure chests, floor loot or supply drops. And yes, as previously announced, Supply Llamas — which look like purple piñatas — are now scattered throughout Battle Royale’s map.
