By way of comparison, fellow free-to-play battle royale game Apex Legends, which released in February 2019, attracted approximately 2.5 million players in 24 hours, 10 million players in three days, and 25 million in one week, according to developer Respawn.
Warzone launched with two 150-player game modes, Battle Royale and Plunder, although developer Infinity Ward has said it will support 200-player matches in the future, and that it’s working on new game modes.
The latest Call of Duty Warzone update introduced a Solos option for the game’s Battle Royale mode.
Call of Duty Warzone is an 18-22GB download for Call of Duty Modern Warfare owners and an 80-101GB download for everybody else.
While Modern Warfare isn’t required to play Warzone, progression and cosmetics are unified across the titles, which share the same Battle Pass and item shop.
