• Ray Boccino has asked that you eliminate Isaac, two of the other main diamond dealers, and their followers.

• 
  Enter the hotel and make your way to the penthouse. The most direct route is to take the elevator and shoot your way in. Be prepared to be shooting immediately after getting off the elevator, as several enemy guards are stationed right at the elevator. Proceed down the hall cautiously if this is the route you select.

• 
  You can also access the penthouse via the roof. This is also difficult because the interior stairwell leads to a glass structure on the rooftop, a bad tactical position.

• 
  The penthouse is also accessible at the rear of the building near the garbage cans. The window washer's lift will take you directly to the top floor. Fight the four guys on the roof. There is also some body armor located there. After the four on the rooftop have been killed, head down and take out the others. Then execute the diamond thieves.

• 
  After you kill the last diamond thief, more guards will enter and you'll have a two-star wanted level. More guards will be on the roof.

• 
  Tip: There is one health packet and one body armor in the mission, both of which are very useful.
