Production notes
During the development of Halo Wars, a design for a cut Sentinel boss - intended to appear as an enemy in the campaign level Cleansing - was concepted by Phil Wohr and modelled through to final game asset by Robert Walden. This model (shown below) remains in the game files of Halo Wars: Definitive Edition albeit untextured. The early design was later reused almost unchanged as the Protector Sentinels introduced in Halo Wars 2.
