On the first mission, you can find a sunken ship next to the UNATCO informant.



Entrance to the north dock where the UNATCO informant is located:



The informant:





If you turn around from the informant, you will see a pair of pile poles connected with fence rails:



If you crawl underneath the fence rails and look into the water, you will see a sunken ship:




If you are unaware, let me inform you: on this ship there are treasures that you do not want to miss. But there is a problem.

A closed door:



The door requires two lockpicks to be opened:


A hefty price, even for the treasures that await! However, there is an alternative way to crack this door open.

On the same dock, you may find a collection of boxes:



Among these boxes is a TNT crate:



This TNT crate is a key to opening the door.



Pick up the crate and carry it straight to the edge of the dock where the ship is located:







Throw it into the water:



Now it should be located somewhere above the door. Don't worry too much about the precision: TNT is powerful.


What you should be worried about is not shooting the crate from too close, as you will take damage:






Instead, take as much distance as you can, aim carefully, and then shoot:





The explosion should open the door:



Enjoy your treasures!
