How do I go in splitscreen on PC?

I want to play with my friends on one screen but I can’t figure out how. Does anyone know?

You need an Xbox controller specifically
PS4 or ps5 controllers won’t work you need an Xbox controller

Thats not true, I figured it out with ps4. You have to download DS4WINDOWS and then you can play with ps4 controller

Yeah, but I meant without downloading anything they aren’t supported, coffee stain didn’t support them but using a software you cam
