Call of Duty: Modern Warfare weighs in at 175GB on PC.
The official listing for the PC version on Battle.net details the huge storage requirement for Infinity Ward’s soft reboot. For both minimum and recommended specifications, you’ll need an eye-watering 175GB of available hard drive space.
While Call of Duty games have in recent years ended up with a three-figure install size (there’s a lot of DLC!), this is by a significant amount the biggest launch storage requirement we’ve seen from a game in Activision’s shooter series.
