Instructions
Begin or continue a case file from the "CSI: Deadly Intent" campaign.
Investigate the crime scene in the selected case.
Inspect every item in the chosen case that can be inspected. This includes items that are not considered evidence. When traveling around the various areas encountered in the case files, keep an eye out for a blue arrow prompt. This arrow points you in the direction of objects to inspect.
Reach a 100 percent inspection rate in one case file to unlock the Meticulous achievement. You can check the statistics stored in your in-game PDA to see how close you are to a 100 percent inspection rate in any given case.
