Gamemodes (also known as gametypes) are the various different types of matches available in the game, each of which uses the game's mechanics with its own set of rules which determines what the goals are and how they must be achieved. Some aspects of the game can be changed through special game options. The match duration usually depends from the Time Limit and/or Frag/Capture Limit. The Time Limit is the maximum match duration, in minutes, while the Frag Limit is the amount of racked kills and the Capture Limit the amount of times a goal was achieved.
