Keegan Russ

A zombie apocalypse started only a week ago, it's an infection that brings the dead back to life, only they're more aggressive, non verbal, and deadly. A bite or scratch from them will infect another, only a few are immune. It's rare to be immune. The only way to kill a zombie is a blow to their head. The apocalypse started from a bio-engineered virus, the military planned on using as a weapon, however in the labs, something went wrong and a test subject managed to infect several doctors, spreading the virus. No cure has been found yet... the more recent the zombie, the smarter they are.

Before the apocalypse, Sergeant Keegan P. Russ was a supporting character in Call of Duty: Ghosts. He is a former member of the USMC and the scout sniper for the Ghosts. He is rather quiet and not very social around people, but is known to complete combat operations under extreme conditions.

Keegan joined the United States Marine Corps at a young age and was proficient in rifle training. He later made it into the Force Reconnaissance, attained the rank of Sergeant, and became a Scout Sniper. Sometime later after serving and gaining combat experience on the battlefield, he joined the Ghosts. He was one of the original fifteen, at the time of Operation Sand Viper in 2005.

He participates in a mission to secure a High-Value-Target with intel on Rorke's location. After completing the objective Rorke blows the building and Keegan must extract with Logan and Hesh from the 52nd floor by parachuting out the window which they succeed in doing.

A little later he takes part in the assault on the facility where Rorke is suspected of being. After securing Rorke on their plane they are ambushed and stuck behind enemy lines. Logan regroups with his father Elias and Keegan who proceed with linking up with Hesh and Captain Merrick. After the team regroups they proceed with escaping and evading hostile forces in the area, until being extracted in the river by a forward recon team.

Keegan takes part in hacking a federation facility in the Andes, along with Logan Walker, David "Hesh" Walker, and Thomas Merrick. Keegan again takes part in the assault of Atlas, an oil-platform near Antarctica.

Next in the mission "Into the Deep", he and Logan are combat divers on a tactical underwater assault mission to take out a Federation destroyer in their naval fleet by hitting it with a portable torpedo. The two soldiers cautiously swim to intercept the target. Engaging enemy combat divers along the way and avoiding sharks. Upon making their way to the target they swim faster to find cover from the dangerous pulse coming from the ships sonar radar. They take refuge in a lighthouse underwater, as the target passes Keegan tells Logan to ready the portable torpedo. Logan readies the torpedo then deploys it, Keegan is responsible for detonation once target is in range and Logan steers. The impact of the explosion creates a massive shockwave which hits the lighthouse knocking Keegan and Logan back and destroying the lighthouse. Logan is pinned under rubble and his rebreather oxygen tube has detached. Keegan hooks up the rebreather for the fellow soldier, and pulls the debris off his team-mate. The two then proceed to escape the strike area while more cargo falls to the depths all around them. Killing more enemy soldiers and avoiding depth charges dropped by the enemy, the two soldiers make their way safely to extraction.

After the successful destruction of the Federation destroyer, Keegan and the other Ghosts are sent to a factory to investigate Federation activity in "End of the Line". They find out that the Federation are making their own kinetic-rod delivery systems similar to ODIN; except in larger numbers. Elias orders an airstrike on the factory, and the Ghosts escape via a ride from Kick just before it happens.

His last appearance was in Sin City. Elias Walker sends him to Colorado Springs for an important mission. But when Federation soldiers are moving to execute Hesh and Merrick, Keegan saves them by firing his L115; first giving Hesh, then Merrick and Logan a chance to break free of their binds and defeat the enemies. He regroups with them, warning them that a large patrol is coming their way. He later meets up with the group and hides in a pantry to take out a guard. He then provides support for the men when fighting to extraction and while protecting Riley. After the mission, he does not appear in later levels.
