Fortnite Mobile on iOS Doing Incredibly Well in US Despite Being Invite Only

Fortnite Battle Royale for iOS is currently an invite-only game, but that hasn't stopped it from taking over the mobile game charts. According to app market data platform App Annie, Fortnite is the most downloaded game across several mobile markets worldwide, and it's also currently one of the App Store's top money-makers.

Right now, Fortnite is the #1 downloaded game and sixth highest-grossing game in the United States, coming in just behind Candy Crush. Those numbers only reflect the iOS version of the game; it's not hitting Android for a few months yet.

But Fortnite's eternal rival, PUBG, isn't about to sit back and watch Epic Games rack up millions of dollars in microtransactions. PUBG Corp just soft-launched an English-language edition of PUBG Mobile on Google Play in Canada. The mobile version of PUBG seemingly plays well, which might be enough to steal away some of Fortnite's audience.

Fortnite versus PUBG is hardly where the battle royale begins and ends, so to speak. Mobile analysis site Apptopia points out some Eastern countries also play "arena" games that never gained much momentum here, including Knives Out and Rules of Survival. Talk about a bloody struggle for players—and that struggle is going to get more intense as the months pass by.
