First of all I'm sorry if this question has been asked several times alredy, I tried searching but all the answers I found were implying you alredy had lots of knowledge out of the blue.
I have God of War III Remastered for PS4 and I want to play it on Chaos mode [the hardest difficulty setting] without having to finish the game first. That's the only thing I want unlocked, I don't want trophies, unlockables or anything else.
The problem here is that I do not wish to spend 50€ for the Save Wizard just to unlock this thing and not using it ever again.
Is there any way to obtain what I want?
