From Warzone Wiki
You can play two kinds of games on Warzone:
- a free-for-all game, or FFA, where every player plays for himself, versus everyone else; however, temporary alliances might be allowed
- a team game, where players are divided into teams and work together to win; there may be only two teams (see ) or more
Sometimes 1 v 1 games, also called heads-up, are treated separately. Technically they're an FFA with two players.
