Locations are usually described using the names that appear on the in-game map. If you can’t find an area, look at the different map levels.

Everything is saved to your account as soon as it unlocks, you can exit missions or reload anytime and completed challenges will still be marked as such. Same goes for mastery level progression.

This doesn't include the challenges Chameleon or Discover Paris. Here is a guide for all disguises:

LOADOUT – At the Red Carpet with Fiber Wire & Coins


Throw a coin into the fountain to get Careful What You Wish For.

Head to the north garden, sneaking in through the three lions fountain entrance. Walk near Helmut, who is standing by the helicopter, to start his conversation so he will call Dalia later. A bodyguard should be walking towards a hiding spot crate. Pacify him, hide his body, and take his gun. Drop his gun somewhere to the right of the pathway so no one sees it. Wait for Helmut to call Dalia and listen to the phone call to start mission story 15 Seconds of Fame. When he’s done, pacify Helmut and take his disguise. Also grab his phone. If you pacified Helmut right after his phone call with Dalia, you should have enough time to drag his body to the same hiding spot crate as before without the other bodyguard seeing you.

Now call Dalia while heading to the dressing room. Sit down in the dressing room chair to get your makeup done and walk the catwalk. After exiting the catwalk, grab the rat poisons in the kitchen.

LOADOUT – At the Palace Garden with Lockpick & Coins


This run can be started at the default location, starting at the palace garden just makes the beginning a slightly shorter distance.

Head inside the palace and enter the bathrooms that are in between the bar and gift shop. The bathroom on the left has an IAGO invitation. Pick up the invitation to get An Invitation Upstairs.

Head back outside the palace and go through the security check that is to the right of the terrace. You have to show these guards the IAGO invitation to go through. Head inside and go right, into the grand hall. Show these guards the IAGO invitation to get I’m Invited.

Go up the pipe to the top floor and you will be on the auction room balcony. Sit down in the auction room chair as agent 47. Dalia will start walking towards you. Wait for Dalia to greet you as Mr. Rieper to get The Mysterious Mr. Rieper.

After she greets you, head towards the attic storage room. Vault over the railing immediately to the right once you enter the room. Go into the bathroom that’s on your left to enter the Voltaire suite. Make sure Dalia and her personal bodyguard are in the meeting room and have started their conversation. Overflow the sink to distract the CICADA bodyguard. Turn the sink off right after pacifying him so others don’t investigate. Take the CICADA bodyguard’s disguise and gun, and hide his body.

We needed to wait for Dalia and her personal bodyguard earlier because otherwise, overflowing the sink would have them investigate it before the CICADA bodyguard does. With him out of the way, overflow the sink again. They will both walk towards the bathroom. Her bodyguard will wait at the door for a second before entering. While he is waiting, pacify him. Dalia will start a phone call in the bathroom so she won’t see you. Headshot Dalia to get A Break From the Auction // Straight Shot // Versatile Assassin.

Head into the CICADA security control room. Grab the remote explosive that’s on the desk right in front.

Head downstairs to the ground floor of the palace and enter the gift shop. Listen to the woman’s phone call to start mission story A Rare Scoop. Find the camera lens and give it to the blogger to get A Rare Scoop. Place the remote explosive in the camera.

In the same room, lockpick the door to the living quarters. Wait for the Sheikh to start walking and lure him to the piano room with a trail of coins, then pacify him. Disguise as the Sheikh to get MS – Guest of Honor.

Leave the piano room through the door going back into the AV center. Grab the fire extinguisher that’s straight ahead, lying on top of a cart. This will be used to knock out Dalia faster.

Head upstairs to the auction room. Sit down as the Sheikh. Place a bid to get Your Excellency. The prompt for placing a bid might take a few seconds to show up. Dalia will now start walking to her office to meet with you. Once she arrives, close the door and knock her out when she’s under the chandelier. Then quickly release the winch and she will be killed by the chandelier dropping, which will count as an accident kill.

Head down to the ground floor of the palace. Pacify one of the CICADA bodyguards around the north garden and take their disguise.

Head to the terrace. There are two men standing in the far corner. Listen to their conversation to start mission story A Private Meeting.
