Epic Games’ invitation–only Fortnite Mobile game has brought in $5.3 million through on iOS within its first 10 days, according to Sensor Tower.

The battle royale title had previously managed to pull in $1 million within its first three days but an increase of players receiving invites has also seen a rise in revenues.

Chart rumble

Fortnite Mobile is also holding firm in the charts. It currently ranks in the top 10 for overall iPhone revenue in a number of countries, including Switzerland where it is second, Luxembourg where it is sixth and the US where it is seventh.

The game is also present in the top 100 for overall iPhone revenue in another 28 countries. However, it is currently only ranked 498th in Japan’s top 500, where NetEase’s Playerunkown’s Battleground-inspired title Knives Out is now sitting at fourth.

In February Knives Out made $24 million globally, with the Japanese market proving to be particularly fruitful for NetEase’s free-to-play battle royale title.

Fortnite’s natural rival PUBG Mobile has recently launched in the West but has yet to begin monetising. However, the chart royale has already started with Tencent’s mobile port spending six days at the top spot in the US iPhone overall download chart following its launch.
