Made a crappy phPBB forum once ... once.
How is it (on PS4) compared to this?
According to the blurb, you just download modified saves and re-assign them to your PS4. Its £30 and has about 30 saves at present by the looks of it.
It also claims to have Dark Souls III / Bloodborne 'cheatsaves' in which when you assign that to your profile, you'll start at the beginning of the game but with infinite souls etc so you could, if to be believed, put every stat to 255 and the only was you can die is by falling off something.
EDIT: Oh and it uses adobe air to run on Mac or PC so you have to have that installed.
I don't know what good it would do as there is a Last of Us Remastered save right at the end on New Game + but I wonder if you load that save then would it unlock all the trophies instantly? So you have a game like that that you would have a platinum for but each trophy would unlock within a couple of minutes proving you have cheated surely?
