"Warped simulation of a World War 2 historical battle set in a quaint French village."
— Map Description
Infection is a multiplayer map in Call of Duty: Black Ops III. It is set in a warped simulation of a French village during World War II. It also consists of a memorial dedicated to "Belgium" which dominates the centre of the map.
There is a sign that says "Waffenfabrik der Riese" which, translated from German, means "Weapons Factory - The Giant" which is a link to the Zombies map Der Riese. In the hotel near the center, there is also a map of Der Riese on the wall.
In one of the houses, two pictures of boxers are seen hanging on the wall, the same ones that can be found in Shadows of Evil. Other references to the map are the boxing gloves that are on a shelf in the same house and a Fumigator in one of the houses which is on its side.
The sign in the center of town states that "Foy City" was established by Corvus.
