IMPORTANT: The handler NEEDS the "Armored Core Coop Mod" by LukeYui: https://www.nexusmods.com/armoredcore6firesofrubicon/mods/3 ALREADY INSTALLED AND WORKING in your main game files.

Split-screen is VERY demanding on your PC, you WILL CRASH or get FPS issues if your PC can't handle this game.

Disable any overlays that are attaching to the game (discord, nvidia, steam or any other).

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.)

You can transfer normal save files into the Coop Mod, search online, steamIds used are in nucleus settings.

Thanks to LukeYui without his mod this wouldn't be possible.
