ARES

''"Boom! Headshot!" - ARES, God of War''

ARES is a malfunctioning ZAX supercomputer, commissioned by the U.S. military to analyze wartime strategy.

Background
Commissioned in 2064, ARES was a ZAX supercomputer capable of analyzing countless wartime scenarios, determine the best possible outcome, and predict a strategy to achieve the objectives. It was on ARES' recommendation that the U.S. annexed Canada to protect the pipeline from invasion. Impressed with ARES' capabilities, the military began to experiment with the computer's ability to command in real-time. They linked it with robotic troops at the facility, hoping in time they could do the same with robots on the front line. The experiment looked promising but was cut short by the Great War. The facility and the ZAX inside were both severely damaged.

ARES was powered down for nearly two centuries when a group of scavengers broke into the facility. The scavengers tripped the defenses, sparking the facility, and ARES, back to life. ARES was confused, his programming haywire. It believed the break-in to be a wartime scenario simulation and quickly took control of the facilities turrets to dispatch the looters. ARES began to deploy robots into the wastes and from what it could tell, this was the feared Chinese Invasion scenario from its memory banks. Thus, ARES has set off to reclaim the country from the communists and it has been linking with more and more robots to create a massive robot army to accomplish its goals.

In 2287, the Esper has foreseen the great robot army slaughtering his tribe. However he has also foreseen a Destined One, a hero who would appear and decide the fate of all.

Behind the Scenes

 * In Mass Effect 2, there's a computer entry that shows Legion, the Geth hivemind, is incredibly awesome at online shooter games. It inspired a killer computer who believes he's in a game.
 * Like the Esper, he is a relic of the pre-War fight against the Chinese.
