Late in the game the game you will get a call to meet
Alex in his office where he will give you the codes to his elevator (
The Key's To The Kingdom Questline). Ignore this request and head straight to the
Crew Quarters and
Dr. Igwe will contact you and ask you to find an item inside a safe in his room. This can
ONLY be done if you saved Dr, Igwe.
If you are fast enough and reach his room you can find the safe before the music stops but if you don't make it in time just simply replay the audio in
DATA - AUDIO LOG. After you have the item make your way back to Igwe in your office and the achievement/trophy will unlock.
