Quake III: Team Arena Cheats (PC)

/headmodel
  The models of Team Arena have interchangeable heads and bodies. If you'd like Gammy's
head on Janet's body, all you have to do is use the Janet model and then type the
following:

  /headmodel *gammy

  Note that you must have an asterisk (*) before the head model's name in order for the
command to work.

  /team_model
  This works similarly to the /model command, except that this will set your model for all
team games.

  /team_headmodel
  This command is the team game equivalent of the /headmodel command; it will set your
preferred head model for all team games.

/g_redTeam and /g_blueTeam
  This command sets the clan for each team. 
  Usage: /g_redTeam Pagans
