This Side Up is a campaign achievement in Halo: Combat Evolved Anniversary and Halo: The Master Chief Collection. This achievement is obtained when a player completes the Warthog ride on the level “The Maw” without being forcibly ejected from the vehicle.

The easiest way to do this is to do the mission on co-op and have one player stay behind while the other does the run. Regardless of whether the driver gets ejected, the player who stayed behind will get the achievement.[1]
