Mission 5: Reclaimer
Objective 1: Infinity sends the Master Chief and Gypsy Company to neutralize the gravity well keeping them on Requiem.
Bonus: Chief picks up a handy jetpack at the start of this mission! And we get to ride along on the gigantic Mammoth vehicle.
Objective 2: Chief and Gypsy Company must disable the particle cannon network which protects the gravity well.
Objective 3: Master Chief leaves the Mammoth and heads alone into Vale Citadel to deactivate the particle cannon network.
Optional Objective: In Mission 5, hijack a Wraith and use it to kill at least four enemy Wraiths on Heroic difficulty mode or harder. Successfully doing this will unlock the “Mortardom” Achievement worth 20 Gamerscore Points.
