In the early hours of Friday morning, Epic replaced Fortnite's Risky Reels with The Block, an area that houses a creation made by a player in the new Creative mode. As you'd expect, players are getting stuck in and building their owns play spaces - and an early favourite is Call of Duty maps.
Players are using Creative mode to build Fortnite versions of the likes of Nuketown, Shipment and Rust, and some efforts are pretty impressive. Here's a short roundup.
Of course, Call of Duty maps aren't the only focus for Fortnite creatives. Players have also spent time recreation old-school areas of the Fortnite map. Here's old-school Factories reimagined, courtesy of redditor Mrhollywood03.
By all accounts Creative mode is a useful tool and players are getting a kick out of messing about with it. It's an extension to the popular sandbox Playground Mode, and is the third mode on the Fortnite title screen, alongside Save the World and Battle Royale.
Epic has said it'll feature creations built in Creative with everyone in Battle Royale, so, you never know, but you might come across a Call of Duty map while out and about.
Either that, or a blast from the Fortnite map's past.
