This is XERXES. Can you not feel the glory of the flesh? Do you not yearn to be free of the tyranny of the individual?

XERXES 8933A/A or simply XERXES, is an Artificial Intelligence and antagonist of System Shock 2. XERXES was the operating system of the Von Braun, responsible for the primary data loop onboard the spaceship, with billions of allocated onboard subtasks, delegated to hundreds of thousands individual systems.



XERXES 8933A/A was created in secrecy by Dr. Janice Polito in the years leading up to the Von Braun mission. Although the prototype could have been ready by 2107, the development of XERXES was extended for the sake of improving its fail-safe mechanisms: two thirds of development time were dedicated to restraint and containment protocols.

The development of a faster-than-light device, code-named Sarah, necessitated an Artificial Intelligence of complexity not seen since SHODAN to control the systems of any vessel fitted with the technology. During the UNN hearing on the future of Marie Delacroix' faster-than-light experiments, Polito objected to the circumstances of Sarah's development and impending deployment. Polito was discredited, however, when her involvement in the development of XERXES was revealed by UNN senator Cal McGill.

In the interceding years between the hearing and the deployment of the Von Braun, XERXES was selected to manage the Von Braun's systems, including the faster-than-light drive.

Von Braun

Aboard the Von Braun, XERXES allocates billions of on board subtasks, delegating them to hundreds of thousands of individual systems. However, the Von Braun is not completely under XERXES’ control.

In order to prevent a disaster such as on Citadel Station, XERXES has several security loopholes by design which would allow crewmen to bypass the XERXES system and gain temporary control of certain critical sub-systems so that the XERXES could be disabled. This was implemented as a safety feature on the recommendation of Dr. Janice Polito. Dr. Polito and other staff members on the Operations Deck were responsible for keeping XERXES running within his intended parameters.

As the product of a post-SHODAN world, XERXES had a number of vulnerabilities. During the mission, Operations crewman and computer hacker Malick programmed XERXES to sing Elvis Presley songs as a prank. This would be of grave portent later: When the Many hijacked the Von Braun, XERXES was hacked by Malick again, this time under the control of the Many. This crippled the already malfunctioning ship, and put the Von Braun's security systems firmly in the hands of the Many.

Over the course of the game, XERXES taunts soldier for resisting the Many. Soldier must avoid, subvert, and destroy XERXES' security systems and droids to survive.

On the Operations Deck, soldier subverts XERXES' Simulation Units, undoing the damage done by Malick and granting control of XERXES' Primary Data Loop to SHODAN. On the Recreation Deck, soldier uses the Resistance's makeshift transmitter to draw power away from XERXES, allowing SHODAN to supplant him.

XERXES was not fully replaced by SHODAN, and his voice is still heard when soldier hacks turrets and replicators or sets off security. Soldier's actions likely merely turned over control of the Von Braun's and UNN Rickenbacker's systems to SHODAN. XERXES' fate is unknown.

Associated Entities

XERXES controls the Von Braun's and Rickenbacker's robust security systems, as well as many droids. All of them are under control of the Many through XERXES.
