Activision's Call of Duty Mobile is a juggernaut. With more than 150 million installs worldwide, the game's big success has helped mobile become Activision's biggest platform by revenue.

The game, which is developed by Tencent's TiMi Studios in China, recently hit a milestone in Australia: 1 million installs. Chris Plummer, Activision's vice president of mobile, spoke to GameSpot about this achievement and a lot more about the mobile game in a new interview.

Plummer tells GameSpot that Call of Duty Mobile is resonating globally, but for the Australia audience specifically, he had a message to share: "Personally, I want to thank the Australian fans. You were part of our beta program and really helped us in the lead up to launch."
