Warzone is a free to play battle royale style video game. This means it is played exclusively online with up to 150 people playing in one match.
Users play as part of a team (or squad) and their aim is to be the sole survivors of the match, after every other player has been killed off. The map is constantly shrinking as the game continues, pushing enemy squads closer to each other.
There are currently over 100 million players worldwide.
