On this page of the guide to Hitman 3 you will find a detailed walkthrough description of the (In)Security Mission Story. You will find yout how to disguise yourself as a security guard at the Burj Al-Ghazali inauguration party and how to get closer to one of the main targets of the Dubai mission, Marcus Stuyvesant.
Different ways to eliminate Marcus Stuyvesant are described on a separate page of our guide.
When you are inside the Burj Al-Ghazali, go to the upper floor, head to the stairs on the left and walk through the crowd to the bar area (point 12 on the map).
Once you are in the bar area, wait a moment and Marcus Stuyvesant will appear. The man will stay on this floor for a while, and then he will go up the stairs next to the bar counter - into the security room.
Follow him into the security room (point 13 on the map) and eavesdrop on his conversation with the guards. You will learn that Stuyvesant is expecting a replacement guard who hasn't shown up for work yet. If you are able to locate the guard and disguise yourself as him, you will be able to approach Marcus without arousing suspicion.
Infiltrating the staff area
Turn around and turn left as you pass one guard. You will notice another lone guard here. Wait in the alcove, and as soon as the opponent moves towards you, grab him and subdue him. Then, change your disguise and hide your body in the closet in the alcove.
If you raise the suspicion of the other guard, hide your opponent's body in the closet and go inside yourself too. When the guard is no longer suspicious, come out of hiding.
After getting the disguise, go down to the bar area (point 12 on the map) and turn left when you reach the bar, then go through the door to the staff area.
Turn right, then go through the double white doors on the left and down the stairs to the lower floor of the building.
Go to the kitchen and then enter the locker room on the right (point 8 on the map). You will find the replacement guard there, talking to one of the female employees. Attack the man from behind and pick up the transfer papers for the new recruit from the bench.
After getting the transfer papers, you can return to the security room (point 13 on the map) where you overheard Marcus' conversation earlier. Introduce yourself.
Gaining Marcus Stuyvesant's trust
When Marcus shows up in the office, hand him the documents you collected earlier and then follow him when asked.
The impressive resume is not satisfactory enough for Stuyvesant and he will want to test your skills in practice (point 17 on the map). Use knives to hit several moving targets. As you're doing this, try to throw the knives at the exact moment when the target is marked - a white circle will appear around the shield. This will earn you Marcus Stuyvesant's trust and complete the (In)Security Mission Story.
