Arcade Owner Achievement in Halo: The Master Chief Collection

Before anything, make sure to turn on "Scoring HUD" in the Campaign Lobby before starting a mission. In order to achieve the Par Score on all ten missions with Halo 2's Campaign, you will want to take three things into account.

First, manually activate the Anger, Famine, Fog, Grunt Birthday Party, Sputnik, and Thunderstorm skulls in the lobby and set the difficulty to Heroic. You will definitely want to activate the Jacked skull on any mission that DOES NOT contain ground vehicles; this includes Cairo Station, The Arbiter, The Oracle, Regret, Sacred Icon, Gravemind, and High Charity. Activating this skull adds an additional 1.20x multiplier and since these missions do not have ground vehicles, it's essential a "free" multiplier since the skull's effects are nonexistent.

Unfortunately, Par Scores cannot be obtained in Co-Op play, so just stick with a solo playthrough of each mission here. Secondly, you will want to try completing the mission as quickly as possible (finishing under Par Time will give a x3 multiplier to your final score) while still killing everything on the battlefield via headshots and multikills; do not skip firefights or leave anyone alive. Lastly, if you do happen to run over Par Time, try picking up the pace as the time multiplier will begin to reduce significantly!

You can use the checklist below for a reference on each mission’s Par Score:

• Cairo Station - 14,000
• Outskirts – 8,000
• Metropolis – 9,000
• The Arbiter – 7,000
• The Oracle – 16,000
• Delta Halo – 10,000
• Regret – 8,000
• Sacred Icon – 7,000
• Quarantine Zone – 7,000
• Gravemind – 11,000
• Uprising – 9,000
• High Charity – 9,000
• The Great Journey – 8,000

Once you beat the Par Score for all thirteen missions, this achievement will unlock.
