- "If you need a job done right, regardless of the risk, Gideon is your man. Captain Gideon turns recruits into advanced soldiers at ATLAS. For him, it’s more than just outfitting grunts with the latest gear. It’s turning them into the best soldiers in the world."
- — Gideon description on the official Call of Duty website
Captain Gideon is a character who appears in Call of Duty: Advanced Warfare. A friend and partner to Jack Mitchell, he assists Mitchell throughout the campaign and appears in almost every mission. He also appears in the non-canon Exo Survival mode, on the map Riot.
Mitchell Joining Atlas, Rescuing the Nigerian Prime Minister and Seattle Power Plant Explosion
After Mitchell joins Atlas, he becomes acquainted with Gideon during a tour of the Atlas headquarters. Gideon takes Mitchell through basic training. He and Mitchell work closely throughout many operations, including the rescue of the Nigerian president and an assault on a power plant in Seattle that had been taken over by KVA forces.
Locating Danois in Detroit
Four years later, Mitchell, Gideon, and Joker are stationed in Detroit in order to find and capture Hades' right-hand man Dr. Pierre Danois. With assistance from Torres, they locate Danois in an abandoned hospital and take him back to Atlas headquarters to be interrogated. After Danois is interrogated by Ilona, they find out that Hades is meeting in Santorini, Greece with his top financial advisors.
Hunting Hades in Santorini
In Santorini, Gideon leads Alpha Team on Hades' compound where he is meeting with his advisors. After a double of Hades is killed, a bomb on the double explodes, killing one of the members of Alpha Team. Gideon and the other member escape with some support of the Sniper Drone controlled by Mitchell.
Mitchell and Ilona escaping from Atlas
After the KVA is defeated and Atlas is at its most powerful, Ilona finds out through a recording from Hades that Jonathan Irons deliberately covered up warnings of the catastrophic KVA attacks of 2055 in order to make a profit through aiding the victims. Although Mitchell and Ilona are determined to leave Atlas after watching the recording, Gideon stays loyal to Irons and insists that the recording was faked. Mitchell and Ilona escape Atlas custody and defect to the Sentinel Task Force, and although Gideon is ordered to find and kill them as they escape the Atlas headquarters, he and Joker deliberately let them both escape from Atlas and he stays behind in order to conduct his own investigation on Irons.
Defection to Sentinel in Antarctica
Gideon is ordered into Antarctica after Sentinel makes a failed attempt to dispose of a large shipment of Atlas' new experimental biological agent Manticore, which can kill anyone who is not on the Atlas databases. Gideon and two other Atlas soldiers hold Mitchell, Ilona and Cormack at gunpoint, but Gideon, who has deduced that Mitchell and Ilona are correct about Atlas and Irons, betrays and shoots the two Atlas soldiers, before helping the Sentinel forces dispose of the Manticore shipment. Gideon joins Sentinel and lifts the lid on an Atlas bio lab in Bulgaria that is producing Manticore. He and Mitchell infiltrate the lab and destroy it, earning the trust of Cormack in the process.
Attack on San Francisco, Assault on Atlas and Incarceration
After Irons declares war on the governments of the world, Gideon assists Mitchell in repelling Atlas forces in San Francisco, but they fail to prevent an attack on the Golden Gate Bridge that wipes out thousands of civilians, police forces and Sentinel operatives. Sentinel launches an attack on the Atlas headquarters in New Baghdad, which Gideon takes part in, but the Sentinel forces are wiped out after Irons deploys Manticore. Mitchell, Ilona and Gideon are unaffected, as they are former employees of Atlas and their DNA is on Manticore's database. The three are taken to an Atlas prison camp, where they learn of Irons' plans to launch Manticore rockets at every major military base in the world. They escape, but Cormack is killed. Mitchell, Ilona and Gideon then vow to kill Irons.
In one final act of desperation, Mitchell and Gideon infiltrate the Atlas base using AST suits, while Ilona guides them. They manage to destroy the Manticore rockets but are forced to abandon their ASTs. Irons confronts them and locks down their exoskeletons, rendering them unable to move; Mitchell manages to break free but Gideon is stuck. Mitchell runs ahead and catches up to Irons, who ends up falling off the top of the Atlas headquarters. Gideon arrives in time to help an injured Mitchell, and the two begin to leave.
