Epic Games’ massively-successful title Fortnite has brought in over $100m (£75.9m) in worldwide player spending during its first 90 days on iOS. The game launched on Apple’s App Store on 15 March having already established a huge fanbase, especially among young gamers.

Despite being launched in invite-only form for the first two weeks, Fortnite has quickly become one of the most successful multiplayer mobile titles of all time, according to figures from Sensor Tower. The game has broken through multiple milestones, bringing in $25m during its first month and passing $50m by the day 45 mark.

Compared to Tencent’s Honor of Kings (known in Western markets as Arena of Valor), another online multiplayer title recently released on mobile, Fortnite has earned almost three times as much in global revenue. Supercell’s Crash Royale remains the figure to beat in multiplayer action games on mobile, having earned $154m during its first 90 days of release.

Fortnite largely earns its revenues from limited-time cosmetic items used in-game, as well as ‘Battle Passes’ that provide users with free items and other bonuses during one of the game’s ‘seasons’. The beginning of the game’s fourth season, which debuted at the beginning of May, saw revenues quadruple for the game as users were attracted and engagement skyrocketed.

“Even apart from Battle Pass sales, we see Fortnite growing its momentum on mobile, and there are no indications of it slowing there – or anywhere else – as it continues its reign as the world’s most popular game,” said Randy Nelson, head of mobile insights at Sensor Tower.
