Handler notes

Video showcase/tutorial: https://youtu.be/obz5UHzYpNM (Video is for COD United Offensive, but works exactly the same for this handler).

Tested with the Steam version of the game and version 1.5.

IMPORTANT: Start the main game once before and change some settings.

When the instances are starting/resizing do not interact with them, the mouse will bug out if you do.

This game has minimal controller support (it isn't even known to have controller support), use your mouse to navigate the menus, also the right stick has a high sensitivity, there is no known fixes for it yet.

Recommended that you add custom resolutions to all your monitors from your AMD/Nvidia/Intel panel (for example if you are using a monitor resolution of 1920x1080 add custom resolutions like 1920x540, 960x1080, 960x540, etc.).

The handler uses names.exe, F2 Host.exe, F3 Restart.exe, F4 Next.exe and safeMode.exe they are made for a better experience in split-screen, if they get deleted by your AV, just disable your AV when you are downloading the handler, they are needed else you will be getting a crash at the start.

About Call of Duty

"Call of Duty" (2003) is the inaugural game in the acclaimed first-person shooter series developed by Infinity Ward and published by Activision. Set during World War II, it provides an intense, cinematic experience that takes players through key battles in the European Theater of Operations. The game features three interwoven campaigns, allowing players to fight as American, British, and Soviet soldiers. With a focus on realism and authenticity, "Call of Duty" introduces innovative gameplay mechanics, such as squad-based combat and the use of iron sights for aiming. Players participate in historic missions like the D-Day invasion, the Battle of Stalingrad, and the assault on Pegasus Bridge, each meticulously crafted to convey the chaos and camaraderie of wartime. The game's gripping narrative, combined with its atmospheric graphics and sound design, set a new standard for the genre and established "Call of Duty" as a landmark title in video game history.
