Just Sayin...I Ain't Dead Achievement in Halo: The Master Chief Collection

This achievement can be obtained easily when going for "Classic" on Uplift Reserve. The aforementioned achievement tasks players in completing the mission without firing a shot or using any grenades, so players will naturally utilize Warthogs and Ghosts to speed run the entire mission. This act of rushing through firefights may leave a small dent in your health and nearly kill you at times, but there are plenty of health kits along the path to your objective so don’t be afraid in stopping to pick one up if necessary. 

If you’re trying to stack "One Way Ride" with this mission playthrough, you will definitely want to avoid picking up health kits though. Overall, this is quite a simple task and should come naturally to those working on their "Classic" achievement.
