It was released on October 1, 2019, where it was one of the largest mobile game launches in history, generating over US$480 million with 270 million downloads within a year.
Players can choose to play ranked or non-ranked matches in multiplayer mode. It has two types of in-game currencies: "Credits", which are earned through playing the game, and "COD Points", which are bought with real-world money. It is possible to play the full game without paying, though some exclusive character and weapon skins can only be bought with COD Points. Apart from standard matchmaking, a private room for both the multiplayer and battle royale modes can also be accessed where players can invite and battle with their in-game friends.
