No weapons are required, but can bring Silverballers to be safe. Go inside, move directly to the front desk, and speak with the person to receive a key card for room 701. Go upstairs to the elevators and enter the one on the left. Wait until the door shuts and climb to the top. Wait there for your first target as he will enter alone. Wait for the elevator to start moving and strangle him, then immediately jump down, grab the case he dropped, and jump back up before the elevator reaches the top. Take his key card and wait for the elevator doors to shut. Then, jump down, go to the seventh floor, and move to the other elevator. Have it go to the lobby then jump up on top before it reaches its destination. Wait until your next target to arrive. Once you have killed him, jump down and get off at the floor he was going to. Exit the elevator and take a right, then take another right and you will see a balcony. Go out on the balcony. Make sure nobody can see you and sedate the employee. Take his clothes and card. Dump him over the side of the balcony. Go downstairs to the casino. Enter the men's room and wait until the guard is alone, then sedate him. Take his clothes and gun, then pick the lock on the other door and make sure nobody is in there. Stash the guard's body in the cooler and go to the eighth floor. Enter the room with all of the guards and go into the bedroom. Drop all of your guns and call the number on the phone. Quickly return to the bathroom where you killed the guard and change clothes when nobody is looking. Go to the lounge and someone will check you. Go to the door directly ahead if the Sheikh has not come out yet. If he has, go back and do it all over again. If not, go through the door and go up the stairs. Make sure he is at least up the first set of stairs before you kill him. Once he is dead, go back to the elevator where you killed your first victim and get the briefcase. Leave to earn the "Silent Assassin" rank.
