Call of Duty: Mobile has been downloaded over 35 million times across iOS and Android devices, publisher Activision said on Friday.

Call of Duty: Mobile released on Tuesday in all countries where the App Store and Google Play are supported with the exceptions of mainland China, Vietnam and Belgium.

Developed by Tencent’s Timi studio, the free-to-play game brings together maps, modes, weapons and characters from across the Call of Duty franchise, including the Black Ops and Modern Warfare series.

The game has achieved the No.1 app ranking on iOS in over 100 countries, according to Activision.

Activision president Rob Kostich said: “The response from fans across both Android and iOS has been amazing. Already, Call of Duty: Mobile has surpassed 35 million downloads on its way to becoming the #1 ranked iOS app in downloads overall, not only among games, but also among all apps, in 100 countries.

“This is an incredibly fun experience, and we’re only getting started. Congratulations to the teams at Activision and at our partner Tencent’s TiMi Studios for making such a great game for players. And special thanks to our fans for their continued support. There is a ton more to look forward to as we release more content and updates.”

Mobile data tracker Sensor Tower estimated on Wednesday that the game had been installed over 20 million times and grossed over $2 million.

Prior to the title’s official launch, Call of Duty Mobile controller support was included in the game’s settings, leading many to believe it would be available upon release.

However, Activision subsequently confirmed Call of Duty Mobile controller support had been removed via an update and is no longer available.

In a further update, Activision’s VP of mobile Chris Plummer said controller support was briefly offered as a test for “a portion” of live players and suggested its removal was due to balance concerns. However, the executive said Call of Duty Mobile controller support may be reactivated in the future in the form of separate game lobbies.

Call of Duty: Mobile is playable on PC via Android emulator GameLoop, which offers mouse and keyboard controls plus “exclusive key mapping”.
