Even if God of War on PS4 has an automatic save system, you might want to make a manual save during the game to make sure you don’t lose your progress. Think about it, a power cut, an unexpected event, a game crash or you just want to take a break from your adventures and enjoy a little sunshine.
It is quite possible to make a manual save in the new Kratos adventures. To do this, open the game menu by pressing the touchpad on your Dualshock 4 or by pressing the options button and then press triangle to open the system menu that will allow you to save your progress. Just choose your save location and you’re done.
Also remember that God of War regularly makes automatic backups as you progress in your journey, you can see this through the icon that appears from time to time at the bottom right of the screen.
