So seeing First and Second Ending I can guess a bit but there are no rules given in the LB itself so...

... is any% done with all missions as well? Even those dreaded Extreme/Subsistence/Perfect Stealth ones that are basically Replay missions?

... how can I backup my current save file if I want to do a good New Game run? I know I could very well go for NG+ at all times, but it would be nice to do an NG run for the restrictions of weaponry, good use of GMP and doing important side ops to progress the story missions! :)

Not many questions, just wanted to clarify with you guys,

much love, Pax

as far as i understood it any% is over once you finish mission 31 or 46... so if you can unlock 46 without finishing all the stealth and extreme missions you can skip them.

what system are you on? on pc you probably can just copy the savefile into a different folder and then delete it.

i know on ps4 you can backup your save to a usb drive or to the cloud
