There are two basic gameplay modes: In Deathmatch, each player fends for themselves and attempts to kill as many opponents as possible. In Team Deathmatch, players are assigned to either team Combine (Blue) or team Rebel (Red) and work together to accumulate more kills than the opposing team. In both of these modes, a player gains one point for killing an opponent and loses one point for a suicide. In teamplay servers where friendly fire is enabled, a player will lose a point for killing a member of his own team. The match will end either when time runs out or when one player/team has reached the required preset kill limit. Whichever player or team has the most points at the end of the match is the winner.
