Epic twitted about a new weapon which arrived earlier today in Fortnite: Battle Royal. It’s a a heavy shotgun and has been released on all platforms. It doesn’t require any download or server downtime to introduce the weapon.
Fortnite recently released the rather large patch, 3.3, which you can see here. That update added remote explosives. These are great for destroying player built fortresses.
Fortnite recently launched a mobile version of Battle Royal for iOS, although currently it’s invite only.
