Thanks for the pressie, bro!
That's an awesome run, great technique with getting the directors disguise at the beginning. I've never really used the audio distraction device so I will have to experiment. I managed to get him into 47's room once or twice by getting lucky with an emetic syringe nearer the bottom of the ramp and distracting him with coins from the bin the in the corridor outside the room.
I think you're right with the last three kills and being able to save time, I may give it a shot in the morning after work. Yuki's kill was also pretty sweet!
Thanks for running it, man, always a pleasure to watch people decimate my work
