Some Tips:
-You will be mostly going around collecting evidence
-It is imperative that you hack doors in order to finish the level
How Hacking is done:
Upon collecting the evidence, many doors are locked. In order to unlock them, you must press Q (enter hack mode) then you will get a screen like this:

Simply click the textbox location on the right side and hold for one second. The door unlocks when the location is recognized. Then Press Q and exit hack mode and proceed to exit



The exit location is marked by green.

Take Flight-You will earn this achievement upon finishing the Level 9

Who am I: You will need to change guises 15 times. The 15 disguise changes have to be done on one level only. According to shadowK, you have to do it in the escape mission. However, I unlocked it naturally as I played through the game.
