Is that possible? Have only seen people with Xbox controllers so far.
Safe, simply connect via radio or cable.
It worked for all of my games that support controllers. I don't have Fall Guys.
It always depends on the game, you have to see if it supports PS4 controllers.
It will probably support the PS4 controller if it is available on the PS4. Most people play with the Xbox controller because it is easier to connect and more enjoyable
