MZ's latest mobile 4X strategy game Final Fantasy XV: A New Empirehas racked up more than 20 million downloads.

The title, developed in partnership with Square Enix, was launched earlier this year and since then has been a consistent top grosser on app stores across the globe.

According to App Annie, the game was the 14th top grossing game on the US App Store on October 18th.

Influential campaign star

Much like its previous titles Game of War and Mobile Strike, MZ recruited the services of a celebrity to lead its marketing campaign for Final Fantasy XV: A New Empire.

In August 2017 it brought in Instagram influencer and model Alexis Ren to star in its new TV and digital ads. Ren has more than 11 million followers on Instagram and over one million on Twitter.

MZ and Square Enix were both recently named in PocketGamer.biz's Top 50 Developer list for 2017.
