Just Sayin...I Ain't DeadG 20

Uplift Reserve on Heroic is probably the easiest choice here. Just hop in a Warthog from the start until you go through the narrow canyon with the Wraith, then trade the ‘hog for a Ghost. From there, just give enemies the widest berth possible while boosting past them.

It’s tough on Legendary, but a halfway decent Halo player can probably handle it on Heroic without too much trouble. I’m decidedly mediocre and managed it in three tries or so.

If any of the turrets give you too much trouble you can try hanging back and using the Spartan Laser you start with to blast ‘em at long range.
