CSI Fatal Conspiracy

Thoroughness in Fatal Conspiracy is based on the % of searchable locations that you look at. This means going fully left and fully right on every screen that you can.

Including the Lab, Brass' Office, The Morgue, and the Interrogation room, zoom in on everything, and go left and right on everything, Just doing any case thoroughly, while looking at all areas of the above locations should be enough to get over 90%

I did the Cse 2 skill, thoroughness and cunning 100%, but i actually didn't unlock this, it somehow glitched and didn't unlock, i did unlock the 100% achievement, but not this one. I think what you got to do, is just load your game date from the case you did this at the end and try not to get 100%. That might help, i will do this today, but this is just a solution if it's glitched ike me, and didn't unlock the first time.

Edit: This didn't actually work, if it somehow glitch try it again in next case. 90% shouldn't be too difficult.
