HITMAN 3

Follow The Tour mission story, becoming Corvo Black until you meet Yates in the Barrel room. From here, a secret mission story will unlock. Follow this to attend the secret meeting and then save Diana. Once you finish this secret mission story your achievement / trophy will pop.

To get this, you'll need to follow two storylines.

Chose the original start zone and get Burnwoods invitation. Head down and present it and choose 'The Tour' stroyline from the menu.

Find the assassin in reception and then follow him, eventually, he leabs over a railing, you have enough time to choke him out and then hide him in the nearby flowerbed, all guests are looking away from it. Put on his disguise and then continue on. After talking to the receptionist, you'll have to find Burnwood and one of your targets at the entrance to the Vineyard.

Then you must inveatigate what's keeping the Vineyard manager. Sneak around and evesdrop on him. You'll have to get a worker uniform, follow the one that walks away from the meeting, there's a dump location near where he ends up. Then take his clothes. Find the knife in the shed in the middle of the field, pick three grapes from the vineyard (field to the right of the entrance as you look in to it). Return to the manager and take the tour.

You can kill your target serveral times during this, the grape press is linked to a challenge. So, if you're going to do it, I'd save first, complete it and then reload as two more can be done through the second story.

At the end of the tour, hang about and listen to the guard talk to the wine cellar manager and head back to the factory floor. Towards the entrance is a screwdriver.
Pick it up and start the bext story. To the cellars right is a dropdown. Dropdown and open the vent with the screw driver. Climb inside and you'll unlock another challenge. Climb up and listen to the workers. Take out the manager without killing him and take his disguise. Then punch in the code on the keypad (1945, a little on the nose but okay).

Pick up the bottle of wine, another challenge completes here. Take it to the guard you saw talking to the cellar manager, who bizzarely doesn't notice your hair has fallen out and still calls you flowers. Follow the guard, now you have to pass a frosk, so find a place to hide your pistol and then continue on.

Listen to the meeting, if you want to present the wine, do so. It does upset the meeting a little if you don't. Next Burnwood will be taken away and you'll jave 10minutes to find her. Make a distraction at the top of the stairs (if you have all shortcuts unlocked) and then take out the guard, hide his body and take his uniform.

Head up to the Villa bedroom, distract the guard at the top of the stairs, preferably drawing him near you, take him out silently then take out the two on each balcony by Burnwood. Remember to hide the guard down stairs on a balcony too.

Follow the instrucrions and sit down. When an event happens, react quickly and knock out the guards. Then finish the job. Hide the targets body in the nearby container and then take his spare suit by the window.
Head down to find Burnwood on the dancefloor.
