Epic Games is making it easier to create and share your best Fortnite Battle Royale moments, thanks to a new in-game feature that will let players record and replay gameplay footage. The new tools are aimed both at content creators who want in-game, cinematic camera features and players who want to revisit recorded matches for a better look at how the action went down.

Those replay tools are coming to Fortnite players “soon,” Epic said. Unreal Engine developers will get access to those features this summer, as part of Unreal Engine’s version 4.20 release.
