Below is an image of all the Gigs and NCPD Scanner Hustles for Watson that must be completed in order to unlock this achievement.
The locations on this map are the exact locations I completed to unlock this achievement. I kept track of my progress on the achievement tracker until I unlocked the achievement.
You might have to increase your Street Cred Level if a location does not appear for you. Also, this is best done right before the point of no return as some Gigs will not appear until certain story missions are completed. I completed all of these locations right before the point of no return (right before the last story mission "Nocturne 0P55N1").
* Reported Crimes: "Don't Forget The Parking Brake", "Needle In A Haystack", "Dragged Up", "One Thing Led To Another", "Dangerous Currents", "Protect And Serve", "Paranoia" and "Worldy Possessions"
will appear after you complete their corresponding Reported Crime NCPD Scanner Hustle (which is indicated by the red arrow on the map).
* The Cyberpsycho Sightings "Six Feet Under", "Bloody Ritual", "Where The Bodies Hit The Floor", "Demons Of War", "LT. Mower" and "Ticket To The Major Leagues" which are located in Watson are not required for this achievement. The exact locations of these Cyberpsycho Sightings can be found here:
