'Someone Else's Shoes' quest walkthrough in Arc Raiders

The "Someone Else's Shoes" quest in Arc Raiders will have you running around Stella Montis searching for androids on Celeste's behalf, as you try to find out more about something called Project Pathos. Stella Montis is infamously one of the most difficult maps in Arc Raiders though, so unless you know exactly where to go, this quest can be a severe pain in the backside.
