Haliekron, Nexus Overlord

Haliekron, Nexus Overlord is a Vex Axis Mind of the Sol Collective with the form of a giant Minotaur. It is encountered in the Vex Network, protecting its node from an attack by the Shadow Legion and The Guardian.

Gameplay
Haliekron is the final boss of the Partition: Ordnance Mission. It appears in a large, circular arena alongside a number of reinforcements, and fights the Guardian with its Torch Hammer and Slap Grenades. It is immune to the physics effects of Sam's viral construct. Every third of health it loses, it will retreat behind an impenetrable barrier, requiring the player to obtain a Data Artifact from the Databank Courier that appears nearby. Once Sam is fed the artifact, he will be able to break the barrier, making Haliekron vulnerable once more. Destroying the Nexus Overlord will complete the mission.
