Clan matches might be played with any team mode :
Capture the flag, Hunt the flag, Team keep the flag, Team deathmatch, team survivor, team one shot, one kill.
The most played game mode is capture the flag (strategy & aim :D)
Usually, "clan matches" just last 30 minutes (2x15 minutes) or 45 minutes in case of tie breaker; but it might be different for some tourneys.. There are not written rules.
There are all kinds of clan (you can get a list here : http://wiki.cubers.net/action/view/List_of_clans) i let you discover them :)
