Six Pedals, Four Directions Achievement in Halo: The Master Chief Collection

This achievement can be obtained fairly early on during the “Quarantine Zone” mission. As soon as the introductory cutscene concludes, hop inside the Specter and be prepared to destroy the Enforcer and Sentinels that ambush your position. After dealing with them, head through the open doorway on the cliffside wall and descend the ramp that leads further into the underground structure.

If you stick to the right side of this room, continue driving your vehicle until you’re required to descend a small ramp that leads to a lower platform. Down here, tucked away in the back right corner, you will find a Flood-controlled Scorpion Tank. Simply exit your Specter and approach the Tank carefully in order to hijack the UNSC vehicle and thus, unlock the achievement.
