The much-anticipated launch of 'Call of Duty: Modern Warfare 3' also introduced the 'Call of Duty HQ' launcher, designed to consolidate the series' games into a single hub, but it's causing confusion among players. The new HQ system allows for managing several Call of Duty installations, including 'Modern Warfare 2' and 'Warzone', from a single interface and is available across multiple platforms.

Players report a cumbersome setup process involving multiple step installs for 'Modern Warfare 3', with potential total file sizes reaching upwards of 200GB. Furthermore, 'Modern Warfare 2' no longer has a separate icon on the PS5's home screen, implying everything goes through the 'Modern Warfare 3' label now, which has puzzled some users.

Streamer and gamer reactions reveal struggles navigating the new launcher interface, contradicting Activision's intentions for making game access easier. Despite this, Activision advises players to use the 'Manage Files' option within Call of Duty HQ's menu for managing game content and claims that the launcher will continue to evolve.

'Call of Duty: Modern Warfare 3' is now available on PlayStation and Xbox consoles, and PC. Separate reports suggest a rapid development cycle of around sixteen months at Sledgehammer Games, hinting at potential development challenges.

Gamers looking to manage their Call of Duty experience efficiently should keep an eye on further updates to the Call of Duty HQ system and make use of file management features to tailor their install size.
