On the official game server, the player can choose one of seven game modes (deathmatch, wingman, war games, arms race, destruction, casual game and competition). After that he will be assigned a suitable server with the default settings. In the home and community servers, the game modes may differ from those named. Apart from official competitions, players can join or leave a server at any time and choose the next map at the end of a game.
