Released on 10 March, the free-to-play battle royale has exploded in popularity, reaching six million players within only 24 hours.
The gamemode places 150 players in the fictional city of Verdansk who must fight to the death and be the last player standing by collecting weapons in an ever-shrinking map area surrounding by deadly gas – normal battle royale gameplay, but with a twist: when a player is slain, they are sent to the Gulag where they can battle another player. The winner of this battle then respawns into the map, and the loser dies for good.
As well as its battle royale mode, Warzone also features a mode called "plunder", where teams must explore the map to collect cash. After one team has accumulated $1 million, all players' account balances are doubled and a timer starts. The team with the most money at the end of that time period wins the match.
Warzone is available on PC, Xbox One, and PS4, available as part of last years' installment Modern Warfare, though the base game does not not need to be purchased in order to play Warfare.
