I can't hear the Spy. I've turned my volume up as loud as I can, and I still can't hear it. Plus, you play without ragdolls. No idea what this replay was about until you broke down and explained it fully.
Yeah, I didn't even think about the fact that most people have ragdolls until today. Woops. And I'm actually surprised you can't hear the spy. It sounds pretty obvious to me, but meh. Whatever. Next puzzle will be more solvable
Seriously, can nobody else hear it? It occurs with the sound of the rifle. I believe it is this sound file: http://www.tf2sounds.com/sound.php?id=1598&stream
