Cast to PlayStation 4 is a feature that allows you to easily control the casting of your PlayStation 4 game characters. This feature is great for creating custom or personalized casts for your games. To cast a character, open the Cast screen in the main menu and select the desired character. Then, input their desired action and location into the Cast bar at the bottom of the screen. The Cast bar will then show up in blue and you can start casting by pressing space on your keyboard or using a controller. Once you have cast your character, they will be available in-game as well as on social media platforms such as Twitter and Facebook. You can also use Cast to control other players in online multiplayer games by using their characters as proxies.
