HITMAN 2

Location: Sapienza
Mission: The Icon
Loadout: Suit + Coin + Lockpick

Head behind the restaurant and enter the basement using the lockpick. Follow the underground area to the door nearest the set, open it and throw a coin inside to lure the nearest guard. Hide his body in the corner. As you exit onto the set throw a coin to have key people look away and scale to the top of the bus and drop inside using the hatch. Hide inside by the far wall for about 2 minutes. Once the target enters, subdue him and snap his neck. Grab his keys from the desk. Get on top of the trailer and wait for the stage crew to move so that he doesn't inspect your coin throw needed to distract the assistant. Slide down the ladder and exit the level using the car.

The following YouTube video shows a very easy way to do this on 'A House Built on Sand" (It's not mine!)

I did this first time, and doesn't involve anything tricky whatsoever. No luck either, its very straightforward.

This solution is a repost from my Hitman 2016 solution of the same achievement


I did this achievement on the "A House Built on Sand" mission

I used Signature 47 Suit, a Lockpick and Fibre Wire.

I headed to the Rugshop where that guard has the key for the backdoor of the VIP club, lockpicked the door without anyone seeing. Headed up stairs picked up a brick, threw it near the ground and lured the bodyguard towards me, and i subdued him took his key, I also subdued the Rug Saleswoman and put both of their bodies in a nearby box.

I ended up poisoning Kong Tuo-Kwang's Hookah Pipe after distracting his guards in the toilet area and subdued them, then sneak into the area where he sits down where his guards used to be guarding where the hookah pipe is. then he becomes sick once he trys smoking the Hookah pipe. he heads to the toilet where you can kill him without a chance of anyone else finding his body.

the same can also be said, if you follow around Matthieu Mendola long enough you will noticed he stops to eat some Tea Leaves, if you time this right with poison the tea leaves pile without anyone seeing you. You can make him head to the toilet once he trys some and kill him he has the documents on him, pick them up and head for a exit, all without changing your starting suit outfit, being spotted trespassing or doing something suspicious or any bodies found, and only Kill the targets. if you done all this then the achievement should pop

While this achievement can be done in each of the three mentioned missions, the fastest way to get it is, in my opinion, during "The Icon" where it takes only around 3 minutes to finish the mission as Silent Assassin, Suit Only, Sniper Assassin as shown in the video below.
