Fortnite has generated more than $1 billion of income from in-game purchases alone.

According to a report from Superdata the insanely popular Battle Royale game has raked in over $1 billion in in-game purchases for Epic Games, despite being on sale for less than a year.

In May 2018 alone, Fortnite generated more than $318 million in revenue. And according to Superdata’s report, the Battle Royale genre is now the most popular in the world – at least as far as streaming and YouTube views are concerned – with over 700 million hours of content involving the genre viewed in May (with MOBAs in second place, clocking up 275 million hours).

Fortnite’s Season 5 kicked off last week, including a new Battle Pass which is likely to see the game generate even more money for Epic Games, and bringing a new map and lots of new skins. If, due to some strange quirk of fate, you haven’t yet encountered Fortnite, check its website out here.
