The much-discussed survival game has been played by millions of people around the world since it was launched in 2017, and new data has underlined the jaw-dropping extent of the title's popularity.

SuperData Research has confirmed that the game earned a staggering $318.3 million in revenue in May alone, and even more impressively, the title stands to make $3.5 billion this year.

Speaking to CNBC, GameSpot vice president and general manager Ben Howard explained: "'Fortnite' is incredibly beautiful visually. It's got a Saturday morning cartoon-like feel and it's very accessible.

"The game is completely free to download and play, with all the monetisation coming on cosmetic items that don't affect the gameplay."

He said, too, that he's even spent some of his own money on the hit game, which was launched in July last year.

He shared: "Sometimes you want that skin for your character. You want that superhero outfit, you want that cowboy outfit. You know, it's hard to say why it's compelling. But it is."

However, the game hasn't been universally well received, with some parents claiming that the title has become a real-life addiction for their kids.
