Currently, if you play Fortnite on a console like the PS4, you might inadvertently be playing against keyboard and mouse players, while yourself using a controller. While keyboard and mouse controls are not officially supported on PS4 or Xbox One, there are kits available that allow for these control setups. That means you may end up in a competitive game with mouse-based players who may have an aiming advantage.
Epic acknowledged earlier this week that Fortnite on PS4 supports mouse functionality, after Patch V5.20 broke that mouse support and it was subsequently restored.
Mouse functionality for PS4 players has been restored!
We are still investigating the issues surrounding Challenges and will provide an update once we have more information.

But as a result, players have started to discuss issues around matchmaking, believing that controller players should be able to stick to just playing against other controller players. A lot of comments to the original tweet in particular complained about the situation.
On Reddit, Epic addressed the issue, offering a statement that seemed to imply that, rather than shut out support for mouse on consoles, they plan to tweak matchmaking going forwards, so that players get matched with others sharing their control scheme.
We're actually working on some matchmaking tech, on the way, that'll pair you against folks based on your choice of peripherals. More info on this coming next week, but tl;dr if you're on KB+M you'll be against KB+M.
It's unclear if these changes will just be for consoles, or will also apply to PC. I'm not going to lie; as a player who is more comfortable with a controller, I'd much rather be able to play on PC and only be matched with other controller players.
Epic says more information will be coming next week.
