Classic Achievement in Halo: The Master Chief Collection

This achievement is best done on Uplift Reserve. As soon as the mission begins, heads towards the objective, up the dirt path where you’ll see a group of Marines taking fire in the distance. There’s an overturned Warthog near your allies, so approach the vehicle, flip it, get in, and begin driving past all the enemy forces and Covenant opposition (Choppers and Wraiths) towards your next objective. 

As you squeeze through a tight canyon past two Wraiths and a Chopper, you’ll receive a checkpoint and spot a Covenant Ghost. Transfer out of the Warthog into this Ghost and now it’s up to you to reach the end of the mission using the Ghost to bypass all the firefights and enemies along the path. Take note that you are able to hold the left trigger to activate the Ghost’s boost but you cannot, under no circumstance, hold the right trigger to fire the vehicle’s weapons; if you do, it will void the achievement. 

For the sake of avoiding convoluted text in describing the route to be taken one you have possession of the Ghost, feel free to refer to the video below as a visual representation of how to complete the mission without firing a shot or throwing any grenades. Thanks for the video footage, Maka!
