Call of Duty Mobile has had the best launch of any mobile game ever after generating more than 100 million downloads worldwide in its first week, according to Sensor Tower Store Intelligence estimates.

Developed by Tencent’s Timi Studio in partnership with publisher Activision, the title’s first week performance puts it ahead of other big mobile game launches like Mario Kart Tour, which raced to 90 million downloads in its first seven days. Other mobile heavyweights such as Fortnite and PUBG Mobile picked up 22.5 million (App Store only) and nearly 28 million downloads, respectively, in their first week.

The majority of Call of Duty Mobile’s downloads came from iOS, where it generated 56.9 million downloads, or 55.7 percent of the total, while Android users accounted for 45.3 million unique installs, or 44.3 percent. Activision’s shooter was most popular in the United States, where it was downloaded nearly 17.3 million times, or 16.9 percent of the total count. India followed with 13.7 million downloads, or 13.4 percent, with Brazil in third with 7.1 million downloads, or 7 percent.
