If you’re looking to play MW2 with a PlayStation 4 controller, there are a few things you’ll need. The first is an adapter, which will allow you to use the PlayStation 4’s touchpad and buttons. The second is a gamepad, which will work with both the PS4 and the MW2 gamepad. Finally, you’ll need some software to help you configure your controller. This software can be found on the PlayStation website or on the game’s website. Once you have it installed, open it and click on “Settings.” In this screen, select “Input.” In this section, select “Controller.” In this section, select “PS4 Controller.” Now click on “Create New Controller.” In this screen, enter your name and email address. Click on “Create” and then click on “Close.” Now open up your PlayStation 4’s console settings and change the input settings to match your new controller.
