Fortnite’s newest update — patch v3.5 — was released today by developer Epic Games, and its main feature is a portable fort that brings a brand new way of building to Battle Royale. The patch also adds replays to Battle Royale, and new skins and questlines for Save the World.

The most heavily teased of this patch's updates has been the Port-a-Fort, a new type of equipment that allows players to create an entire fort with just a simple throw. As soon as the Port-a-Fort hits the ground, it instantly pops up a three-story-tall building wherever it's thrown. While some more seasoned players might see this as just another structure, it should provide newer players with a glimpse of what it’s like to build as fast as some of the best players in the world.
