During Nintendo's E3 2018 showcase, the company announced a surprise-launch for Fortnite, Epic's wildly successful battle royale. Predictably enough, when the biggest game around launches for the biggest console, it gets quite a response.

In a tweet, Nintendo of America revealed that Fortnite has already been downloaded more than 2 million times on the Eshop. That word came just barely a day after launch, which makes for a remarkably fast adoption rate. That quick response may have contributed to some matchmaking issues immediately after launch, which Epic quickly addressed. The Switch version also plays nicely thanks to cross-platform play with other platforms, besides PS4.
