VIP

VIP is a multiplayer gametype in the Halo 3 Beta and possibly Halo 3.

Each team is assigned a "VIP" which they must protect while trying to kill the other team's VIP. Each team can only score by killing the opposing VIP. Whoever kills the VIP will become their team's VIP after their next respawn. This might also be what the "leader" is in the also new game type Escort. It could be considered a team Juggernaut.
