The mobile version of videogame franchise “Call of Duty” racked up 100 million downloads in its first week according industry analyst Sensor Tower.

The figures dwarfed the debuts of previous smashes including “Fortnite” and “PlayerUnknown’s Battlegrounds”. PUBG, Fortnite and Electronic Arts’ “Apex Legends” scored 26.3 million, 22.5 million and 25 million respectively in their first week of release.

Sensor Tower said this was by far the largest mobile game launch in history in terms of the player base that’s been built in the first week.

“Call of Duty: Mobile” was launched by its publisher Activision Blizzard on October 1.

Sensor Tower said the numbers reflected worldwide unique downloads across Apple’s App Store and Google Play in the period since.
