Today’s Fortnite update came a little bit later than we’re used to, but that’s easy to forgive when so many fun things are being added to the game this week.

We have more details about the Rift-To-Go item, which was added in this update, including a video below that shows it in action. It turns out that Rift-To-Go won’t be a permanent addition to the map when you use it; the rifts only stay in place for ten seconds. So, other players can jump through, but it won’t be there for long.
