You can get everyone to be free, and let Frenni, drown Afton, get everything to 500 then when at home get Coding to 800, ignore the paranormal for now then missing persons at work, when coding is maxed, and Missing persons at 800 max out paranormal, and at this point you should have found the USB then you can max out Missing persons, don't activate the thunderstorm, don't act like the perfect employee, do the heist without a storm if you got the dialogue mentioning a USB drive and missing persons case maxed out after, not before, that USB then you can save Vanessa.
Missing persons seem to be extremely important if not necessary.
I'm still looking for where Zero's name is though.
