Halo: The Master Chief Collection

This mode is like a game of cat and mouse. One team has a Juggernaut who acts alone and tries to kill as many players from the opposing team as possible. For each kill, Juggernaut receives one point. On the other hand, the other team consists of the remaining players in the match and their goal is to kill Juggernaut. The player who kills the Juggernaut becomes one themselves and begins to accumulate points for killing players of the opposing team.

This achievement can be obtained in a Custom game alone. Start a game in this mode on any map and you will automatically become a Juggernaut. Just wait 30 seconds and the achievement will unlock.
