Following a day-long delay, Epic Games has released the newest update for Fortnite. The 3.3 patch adds new content to both Battle Royale and Save the World modes, with the former getting several new features.

First up for Battle Royale is a new weapon, remote explosives. These are pretty self-explanatory, allowing you to place a bomb and then detonate it from a distance. These appear to be ideal for dealing with player-built fortresses. They are a Rare-level rarity item and their addition has resulted in Smoke Grenades being "vaulted," meaning those are no longer available in-game for the time being. Remote Explosives come in stacks of four, with a maximum of 10.
