How to complete the “Pick Your Poison” Challenge in Dubai in Hitman 3.
First we need to get the Lethal Posion that is dropped by the Assassin wearing the green shirt.
Then get a Penthouse Guard Uniform to access the 4th Floor.
Once on 4F go into the storage room and call in the Chef by interacting with the Ice Machine.
Take him out and use his outfit to go into the kitchen, interact with the plate twice to add the poison then ring the bell on the other side of the counter to call Carl Ingram to pick up his dinner, now just wait untill he eats and dies.
