The Master Override is a unique quest item in Horizon Zero Dawn.

In Horizon Forbidden West, the Master Override is incorporated into the Champion's Spear and Nora Legacy Spear as opposed to being an item itself.

History

In the Old World

The Master Override was originally created as a means to purge GAIA and/or her subordinate functions if necessary. Although Elisabet Sobeck initially resisted Ted Faro's push to install a "kill switch" in GAIA, she eventually relented and installed the Master Override after GAIA sided with Ted.[1][2] The device was left in the control room of GAIA Prime.[3]

In the New World

Horizon Zero Dawn

Aloy learned about the Master Override from a message left for her by GAIA, where she told Aloy to retrieve it from the ruins of GAIA Prime so it can be used to purge HADES.[4][5]

Aloy found the Master Override, attaching it to the lance given to her by Sylens[3] and using it to purge HADES.[6] However, Sylens had rigged the lance to instead broadcast HADES to him[7] for interrogation, not purge it.[8]

Horizon Forbidden West

When Aloy encountered HADES again outside LATOPOLIS, she used the Master Override to properly purge the rogue subordinate function permanently.[9]

Under GAIA's instructions,[10] Aloy used the Master Override to return AETHER, POSEIDON and DEMETER to their original code state so they could be reintegrated into GAIA.[11][12][13]
