Hitman: Blood Money/House of Cards

Lateef
First, go to the receptionist desk on the right to get your room key. Then go up the stairs, and onto the left elevator. Wait for the door to close, and then climb the hatch. Wait on top of the elevator until Lateef comes in, equip the fiber wire, and strangle him. Take his keycard, get his suitcase (it fell back into the elevator), climb the hatch again, and leave it there. You’ll need to come back and get it when you're done with everything else.

Schmutz
Get out of the elevator on the eighth floor, go to the elevator on the right, wait for the elevator to get there and press the lobby button. When the elevator is on its way down, climb the hatch and wait for Schmutz to come out of the casino. He makes his way to your elevator. Wait for the door to close and the elevator to start climbing to strangle him as well. Take his keycard. Don't forget your rifle case. Wait for the elevator door to close when it gets to the seventh floor to climb down. When it closes, get down and press the "Open Door" button.

Sheikh
Get out and go to the room that the agency rented for you, 701. Go out onto the balcony, unpack your rifle and put it on the ground. Now go down into the casino, head right. Go through the first set of double doors that you see on the right wall. There will be another door to your very far left when you enter that room. Go through it. Walk straight down to the middle of the hall to the first door on your right. Go through it. You'll be in a bathroom. There are only two people that enter the bathroom, a civilian and one of the Sheikh's guards. Wait until everyone is out of the room so you can pick the lock of the door on the opposite side of the room from where you walked in. There's a freezer where you can store a body in there. Don't go in that room though. There's a patrol that comes in there every once in a while. If you time it just right, you can sedate the guard in the bathroom, take his clothes, and drag him to the freezer in the next room without anyone seeing.

After you get the guard's uniform, get outside to the hotel, get onto an elevator (it doesn't matter which), and go up to the eighth floor. Use the key card that you got from Lateef to get into his room (which is guarded; hence the guard uniform you had to snatch). Go into the bedroom, and use the phone on the desk to call the Sheikh. Now run to the elevator, down a floor to the seventh, to your room, 701, out onto the balcony. Get your sniper rifle and aim down into the little outside square surrounded by the casino. The Sheikh will come out there and stand to where you can just manage a headshot.

Escape
Now you can head back out of your room. Get back onto the elevator to the left. Wait for the door to close, climb the hatch, and grab your payment suitcase. Climb back down and go to the lobby. Head down into the left side of the Casino. Keep against the left hand wall, to avoid the security camera above the fire exit door. Go out the fire exit to the back alley and escape.
