Want to see Hitman's Paris level cleared in 15 minutes? Here you go. Watching this back, it's not a smooth run and I reckon I can get it down to 10 minutes easily. In my defence though, this was only my third go and I decided to change some stuff without testing it first because I'm an idiot.
It's a good starting point though, and shows one of the quickest ways to get through the level without alerting anyone. It's also only one of way too many options to cover here, so if you want to know more about the full episode one experience then checkout my full Hitman review.
