Call of Duty Mobile hit 100 million downloads in its first week, beating the 90 million downloads racked up by Mario Kart.
Activision is bringing Call of Duty: Mobile to iOS and Android. It will launch later this year as a free download.
The game will include classic Call of Duty multiplayer modes such as Team Death Match and Free-For-All, and fan-favorite maps like Nuketown.
There is no pre-order app on iOS but you can do it on this website.
