The zombies of Infection

On Infection, every zombie type of Outbreak comes back except the Charger, and four new ones join them: the Spiker, the Oozer, the Meatbag and the Goliath Exo Zombie.

Spiker

Red eyes and spikes all over the body. Shot in the torso, it throws shrapnel that hurts the players and the zombies around it, so headshots are the safe way to kill it.

Oozer

Covered in green acid that it leaves in puddles where it walks. The puddles hurt the players who step in them. Oozers come in with the regular zombies from round 5.

EMZ

The Electro-Magnetic Zombie, wrapped in blue electricity. A hit, or a boost away from it, shuts the player’s Exo Suit down for five seconds. It starts to appear around round 4, and does nothing more than a normal zombie to a player without a suit.

Meatbag

A zombie in tactical armor and a helmet, with white glowing eyes. It takes longer to kill, resists headshots and cannot be turned into a crawler. Once its helmet is shot off, it starts to run.

Exploder

Covered in fire and green liquid. It blows up when a player gets close, killing the zombies around it; if it is left alive too long, its blast grows. It appears after the first Host round.

Security Dogs

On Infection they have no rounds of their own and spawn among the zombies. Some behave like EMZs, others like Exploders.

The Goliath Exo Zombie

The Goliath

A soldier who wore a Goliath armor and turned, bloated with muscle, carrying a riot shield and a hammer made from a drain cover on a concrete arm. Two hits kill a player, three with Exo Health.

Its weapons

Like an EMZ, it shuts down the Exo Suit of a player close to it, and it fires heat-seeking missiles that explode in an EMP. It knocks over and can kill the zombies in its way, and it destroys the Distraction Drones it is drawn to.

Its rounds

It first comes on round 10, with other zombies. Once killed, it drops a Full Reload.

Love Tap

Killing a Goliath with a melee attack earns the achievement of that name.

Host rounds and the infection

The Host zombie model, with boils over its left eye and needles in its body, Infection, Call of Duty Advanced Warfare Zombies

Hosts

Deformed zombies with a cluster of boils over the left eye, a green glowing right eye, needles in the body and orange trousers. They come on their own rounds, announced over the loudspeakers, always sprint, and do not gain health as the rounds go up.

Decontamination Zone

In The Pit, below the Sewer junction, for 250 points. Five Hosts killed at once by it earn the achievement One Man’s Poison…

The infection

A Host hit infects the player, who then has 60 seconds to reach the Decontamination Zone. Each new Host hit takes five seconds off the timer, a hit from any other zombie three seconds. The last zombie of a Host round drops a Full Reload and cures every infected player.

A co-op death

A player who dies of the infection in co-op comes back as a Host controlled by the game, tougher than the normal ones.

The special rounds

The game script of the map sets the first special rounds:

Round	Type
6	Civilian Extraction
8	Host round
10	Goliath round
12	Civilian Extraction
14	Host round
17	Civilian Extraction
19	Goliath round

From round 12, a Civilian Extraction round comes every five rounds, and two rounds after each one comes a special round, Host and Goliath in turn.

Toxic gas rounds

Infection also spreads its gas over the map itself. From round 11, then every three or four rounds, one area turns into a Toxic Gas Zone, and a player who walks in is infected as if hit by a Host. The gas can only cover three areas: Atlas Command, Value Voltage and Burger Town. Players report that around round 30 all three are contaminated at once, which leaves the Sewers, The Pit and Hoard More.

In the First Room

Doors closed, a game of Infection is played in Hoard More against all of these enemies. The warehouse is never gassed, but the Decontamination Zone is out of reach, so a Host hit can only be cured by killing the last Host of the round within 60 seconds. Without an Exo Suit, the EMP of the EMZs does nothing, but the Goliath still kills in two hits.
