All Key Data locations and solutions
Search the indicated locations and complete the listed tasks to collect all hidden Key Data and get the "Researcher" trophy. It is also needed to buy certain skills and upgrades. The Key Data locations are shown in-game and easy to find. Open the research app on your phone and press Triangle on a key data skill. It will show you the rough search area on the map, not always the exact location. You can use the Quadcopter and press the Right Analog-stick to scan the world for nearby collectibles. Figuring out the solutions to these puzzles is the harder part. Many of them require the RC Jumper or Quadcopter (RC Jumper is one of the first story unlocks; Quadcopter must be bought in Hacker HQ). One Key Data requires the "Environmental RC" skill (costs two research points). All the others can be found without the use of skill upgrades. You can reach all key data early in the game, after unlocking the research app. They are saved instantly when you collect them, and none are missable. You can also view which ones you have found in the research app.
