- "The infection has spread to rural America, and everyone's favorite burger joint! Fight with up to 4 players against endless waves of mutant zombies!"
- — In-game Description
Infection is the second (chronologically the third) Exo Zombies map featured in Call of Duty: Advanced Warfare. This map takes place at an Atlas command center centered near a Hoard More storage facility, a Value Voltage gas station, a sewer, and a Burger Town restaurant, which are all overrun by Zombies.
As in Outbreak, the players first start out with no exoskeleton, an Atlas 45, and 4 frag grenades. They must open doors to get to the Sewers to obtain the exoskeletons. Activating the power switch is required to be turned on to access Exo Upgrades and the Exo Suit, but in Infection, it is required to use the 3D Printer, too. The map introduces multiple new zombie variants, each with unique characteristics and one with its own special round with other zombies. All of the zombies from Outbreak return, with the exception of the Charger.
Along with the Hosts from the first map and this one, the map includes Toxic Gas Zones, that will infect the player if they enter the area. If a player is infected, they must get to the Decontamination Zone in the Sewers in order to cure themselves.
This is the starting area of the map. It has two doors leading to the Atlas Command and the Value Voltage with both doors costing 1500 credits each.
- MK14 - 500 credits, in the room with the Electrified Floor trap
- Bulldog - 500 credits, near the door leading to Value Voltage

Value Voltage is the uppermost part of the map. Another 3D Printer location, an Upgrade Station and Exo Soldier are also located here. It also has a doorway that leads to the Sewers with a cost of 2,000 credits.
- MP11 - 1000 credits, above the gas station

Opening Scene Transcript
Oz (narrating): When we met, we only had two things in common... The wrong place, and the wrong time.
Oz (narrating): When you're facing a thousand mutant zombies eager to spoon out your brains... you learn to work together.
The three then open fire on the zombies. Oz quickly taps Kahn on his shoulder, and the two switch positions.
Oz (narrating): Lilith shot her first gun that day... like she was born to do it!
Lilith fires her HBRa3 at the zombies, but the gun quickly jams.
Lilith: Fuck, it's jammed!
Kahn: Heads up!
Kahn tosses Lilith one of his Atlas 45 pistols.
Kahn: You're welcome.
Oz (narrating): As for Kahn...
Kahn fires at the zombies, but gets pulled down by one on his right side.
Kahn: Son of a bitch!
He punches the zombie and gets up.
Oz (narrating): ...he got his hands dirtied for the first time in his life.
Decker boosts toward the group, and punches a zombie heading for them.
Oz (narrating): And Decker enjoyed it all a little too damn much.
Decker grabs a zombie and throws it off the bus, while shooting at another one. He then grabs another zombie and shoots it in the head.
Decker: Take that you zombie shit! WOO!!
Oz (narrating): We were lucky to have found each other, but our luck was running out just as fast as our ammo.
The group continues making a last stand against the zombies, but finds their ammunition quickly running out.
Lilith: Shit! What now?
Oz knocks back several zombies with his CEL-3 Cauterizer.
Oz: You still got your fists, and your teeth!
A zombie boosts up and lunges at Oz, and subdues him.
Lilith and Decker are also quickly swarmed.
Lilith: Aah! No!!
Decker: Get off me, motherf-
Kahn kicks a zombie off the bus.
Kahn: Yeah? You want a piece of me, you maggots? Come on!!
The zombies begin to surround Kahn. As the group nearly meets their end, a Warbird appears and opens fire on the zombies, saving the group.
Oz (narrating): We should have died right then and there, but Atlas was all of a sudden, feeling generous.
Several Atlas employees in hazmat suits begin to evacuate the group from the site. The scene switches to Kahn's first person view, as one of the employees checks on him.
Atlas Employee: Stabilizing... They're in stasis. Prep for transport.
Kahn is then shown in a bodybag, being put on life support. Several Atlas vans are shown heading towards an unknown destination.
Oz (narrating): I don't know how long we were out... but it was long enough for things to go from bad, to worse.
The vans arrive at a Burger Town restaurant. The scene quickly changes from nighttime, with the restaurant intact, to daytime, with the restaurant now partially destroyed and up in smokes. Scene fades to black.
Ending Scene Transcript
The ending scene gets unlocked after saving a total of 25 civilians.
A zombie straggles toward Kahn, who shoots it with his pistol.
Kahn: We're clear, get up here!
Lilith, Decker and Oz climb up onto the roof of Burger Town.
Lilith: I don't like this.
She turns around to find a zombie trying to climb up, which prompts her to shoot it in the head. The group then opens fire on the oncoming horde.
Decker: We got the high ground, what's not to like?
Decker punches a zombie trying to climb up.
Oz: We're cut off, that's what.
The zombies increase in number, as they surround the rooftop.
Oz: Dammit I told you, this is gonna fucking suck.
Suddenly, the zombies are shot down by machine gun fire.
Lilith: It's him!
The group turns around to find a Razorback VTOL shooting at the zombies. After clearing out the horde, the VTOL then shines a spotlight on them.
Oz: Woahohoh, what the fuck, man!?!
A voice then comes out from the VTOL.
Unknown Voice 1: Do not move, stay exactly where you are.
Kahn: What is this!?!
Unknown Voice 2: On your knees! Hands behind your head! Resist and we will open fire!
The group then gets down on their knees. Troops begin to rappel down the VTOL, and hold the group at gunpoint. The camera zooms in on the shoulder of one of the troops, which reveals the Sentinel Task Force logo.
Lennox, the Sentinel Captain, then approaches the group.
Lennox: Been watching you a long time. Atlas did a real number on your heads, didn't they?
He then holds up his pistol at them.
Lennox: Nothing personal, but one of you has to go.
Scene fades to black.
