Hitman is a series of puzzles where the goal is to kill one or more targets with nobody noticing, and no other casualties. In the last one I did, I had to take out a wandering guard (easy enough, but someone will find the body), kill a guy whose wife is standing next to him, and kill a guard with a specific outfit that all of the nearby witnesses can see through with a specific weapon that is on the other side of the witnesses. I also am not allowed to drop the weapon once I pick it up, and carrying around a murder weapon is going to draw attention.
I'm pretty sure I was supposed to change outfits before the last kill, take out a camera, draw another guy wearing the needed outfit near me, time the knockout so nobody is looking, hide that body, change outfits, then kill the last guy. I couldn't get the timing down, so I just restarted that mission with a bunch of explosives and took out all of the witnesses, then came back after the guards quit looking for whoever blew everything up. Over a hundred people got a lower final score than me, which sounds good unless I tell you that over 8,000 people did better. While I technically won after a lot of losses, it's the worst win I've accomplished, and was done out of being tired of losing.
