This Oliphant Has No Brakes
This Oliphant Has No Brakes is an achievement in Halo: The Master Chief Collection. It is unlocked by beating the 90,000 point par score on the level Coastal Highway. The achievement is worth 10 gamerpoints. Though it can theoretically be unlocked on any difficulty, more points are awarded in campaign scoring when playing on higher difficulties.
Players can earn significant points by destroying unoccupied Covenant vehicles as the game does not differentiate between piloted and empty vehicles; Halo 3 and Halo 3: ODST are the only games in the Master Chief Collection with this campaign scoring quirk.
