Hitman: Codename 47 - The Lee Hong Assassination - Kill Everyone Challenge (Remastered)

This is a new, 1080p60 take on my Lee Hong Assassination Kill Everyone challenge, as my previous video was so compressed at 480p that it was barely watchable, if at all.
Original description, which explains certain details about what goes on in this run:
"Hello and welcome to probably the only Kill Everyone Challenge for this level on RUclips! This level is big and full of rooms and hiding spots, which makes for perfect strategies in taking out everyone without practically game-ending yourself in the process.
The C_1/Post_Laptop/Kills/2/ kill in the mission results is actually Agent Smith if you don't rescue him, I guess they forgot to put an actual name there or to make him an actual objective. In the briefing, rescuing him is an objective but in-game you aren't forced to do it unlike the other objectives, which is odd and probably explains the game's confusion as to why he's dead. Killing him yourself directly instead of leaving him alone fails the mission instantly, though.
The old man cannot be killed or else the mission will fail, whether before giving the Figurine to him or after."
