Mission 21: Hunt for the Phantom

Hunt for the Phantom is the twenty-first mission of Halo: Spartan Assault.

Introduction
With transportation secured, one last hurdle remained in getting the colonists safely off of Draetheus V. The leader of the Covenant forces, Merg Vol, was still present on moon X50, providing the remaining Covenant forces with a rallying point and cry. If the colonists were to leave Draetheus V's orbit alive, Merg Vol would need to be terminated.

Spartan Palmer would need a way to get to the moon unseen, but the Covenant knew about her stolen Spirits and would likely open fire on any of these ships trying to land on the moon. Palmer suspected the Covenant's officer on Draetheus V, Parg Vol had a personal transport hidden away. After completing the evacuation operation, locating Parg Vol's ship became Palmer's highest priority.
