Halo: Combat Evolved/Juggernaut

In Juggernaut, everyone is on a team against the player who was chosen to become the Juggernaut. If you are the Juggernaut, you will have enhanced powers. Depending on game settings, you may run faster, have more shields, have increased health, have damage resistance, have unlimited ammo, have invisibility, or have a melee boost. While the Juggernaut is stronger, all the other players must work together to kill him. The player who kills the Juggernaut is reward as being the new Juggernaut, and gets all the abilities that are enabled.
