The eleventh major installment in the Call of Duty series, the game was developed by Sledgehammer Games for PlayStation 4, Windows and Xbox One, while High Moon Studios developed the versions released on PlayStation 3 and Xbox 360, and Raven Software developed the game's multiplayer and the Exo-Zombies mode.

Infection is the second (chronologically the third) Exo Zombies map featured in Call of Duty: Advanced Warfare.

The 2  mouse button is the third button on the user's mouse, which is usually the middle mouse button (often a clickable scroll wheel).
