Cut Halo 5: Guardians enemies

During the development of Halo 5: Guardians, a number of various enemy types were concepted and prototyped by 343 Industries for inclusion in the game, though were ultimately cut for various reasons.

Mining robots
One of the early drafts for Halo 5 seems to have involved automated mining robots used by the Liang-Dortmund Corporation on Meridian. A number of sketches by Gabriel Garza, alongside some more detailed paintings by Nicolas Bouvier, indicate that they would have been fought by Blue Team on the planet.

Covenant
Concept art by Gabriel Garza depicts a form of Sangheili warrior with Promethean augmentations.

Cavalier
The Forerunner Cavalier is a deleted Promethean construct that was intended to be introduced in Halo 5: Guardians. The Cavalier was apparently intended to start out as an empty shell, which would then be filled by the Cavalier itself. The Cavalier was intended to use a Forerunner polearm weapon (possibly similar to the hard light staves first appearing in 2015's Halo: Hunters in the Dark) and was capable of shielding itself. The Cavalier design eventually became the basis for the Warden Eternal.

Mechs
A number of Forerunner mechs were concepted by both Gabriel Garza and Paul Richards for Halo 5. These concepts overlap with some of the other enemy designs featured on this page, and it is likely that they were created as part of the same exploratory process during the game's development. However, due to a lack of distinct commentary on these concepts, they are presented as one gallery.

Packmaster
The 'Forerunner Packmaster is a Promethean enemy type cut from the release of Halo 5: Guardians worked on by concept artists Gabriel "Robogabo" Garza and Paul Richards. Due to its name, the Packmaster likely led Promethean Crawlers. It is seemingly equipped with a Z-250 lightrifle. The Packmaster did not make the cut for the game, however, early 3D models indicate that the designs may have later been re-purposed as the Promethean Soldier.

War Sphinx
Concept art for a Forerunner War sphinx was produced by Paul Richards. Little else is known of this concept, including whether it made it into further production.
