LOL my brother used to play Hitman on straight goon mode, just murking everyone. I'm like dude its called Silent Assassin but he didn't care....I hear ya. I remember they used to say you could go through levels of the Hitman games without killing anyone. I'd always start out a level trying to sneak through it, but eventually something would go wrong and I'd get found out and I'd leave entire lobbies full of people sprayed.
Hopefully it's not incredibly difficult to go through the game without killing.
