replay is a recording of a game that you can play back to study the game or a player's technique. It is more than just a recording of the game, because you can move through the replay in three dimensions. The Fortnite feature that you can use to make a replay is called Replays. This feature has to be enabled to work with your Creative islands. To do this, go to the Game Menu, click the gear icon, then click Settings. On the Game tab, scroll down to Replays, then set the Record Creative Replays to ON. When enabled, this feature can record an entire four-hour play session, but the recordings are saved in individual 30-minute files.
The Replays feature is also great for setting up screen captures or video clips to share on social media. For more info, see How to Use the Replays Feature.
