Even if you are playing as a single player in Online Mode, the PS4 will disconnect from the internet in Rest Mode, which will cause you to return to the Main Menu, losing all your progress on a Mission. However, keep in mind that this will not work if the game is set to Online Mode.
When the console is placed into Rest Mode, the game will pause at exactly that point, and when returning to the game, you'll be able to start exactly where you left off with no additional damage. NOTE: This has only been confirmed to work on the PS4, and has not been tested on the Xbox One or Nintendo Switch. If you absolutely need to pause the game, however, there is one solution available! How to Pause the Game Use the Console's Rest Feature On in-game menus like the Inventory Screen, Map Screen, the so-called “Pause Menu”, and even the console's home screen, gameplay will continue and enemies will attack you mercilessly. There is no option to pause within the game itself.
