Call of Duty: Warzone, the new battle royale (BR) mode from developer Infinity Ward, now has more than 50 million players, Activision announced on Friday.

The milestone has been reached just one month after the game's release, making it one of the fastest-growing free-to-play titles in the game industry. Warzone previously hit 30 million players just under two weeks after launch.

Warzone was released as a standalone download on consoles and PC. It does not require players own any other software and it is also free.
