Fortnite launched for Nintendo Switch back in June in the midst of E3, and the popular battle royale game is unexpectedly a huge hit on Nintendo's hybrid console. Now, Nintendo has revealed more details on just how wildly popular the game is on Switch.

In an earnings report, Nintendo revealed that Fortnite has been installed on "nearly half" of all Nintendo Switch consoles worldwide. As of September 30, Nintendo sold 22.86 million Switch units, so that means Fortnite is downloaded on around 11 million of them.

While that is a massive figure, Fortnite is free-to-play, so the more important data point is how much time people are playing the game and how much money they are spending on its various microtransactions. Nintendo said only that "many people" are playing Fortnite on Switch, which is "boosting the overall utilization ratio of Nintendo Switch."

Nintendo added that the Switch edition of Fortnite is compelling because it's playable on the go via the tablet controller. Of course, the mobile editions of Fortnite for iOS and Android are also portable, but the PS4 and Xbox One editions are less so.

Fortnite's next big update has been delayed, but while you wait for that you can check out the game's new, limited-time Halloween-themed event called Fortnitemares.
