I disagree on your assessment of the teleport. I knew someone teleported to his left in the demo. The teleport *bampf* sound was leftwards of him, and he had the ability to see the guy aiming that way(about tick 3000).

I found tick 2500 more interesting. Watching it in wireframe, he aims for the guy's head. Without, he seems to be aiming at a random wall. And prior to that, he'd only heard footsteps outside his room.(at tick 2100)

Dennnn: Was this demo just adding for completion's sake? The 3 seconds of gameplay just seem to be him hearing footsteps and killing the guy with a spray of bullets. Or am I missing something?

den2: Only demo where I saw him shoot when there was no one there. And why did he ignore the elevator, wish I had the minimap to know if someone was watching.
