There's some fucking crazy grenade jumps early on and bear in mind he's playing normal Quake, not QuakeWorld with it's higher speed and lower gravity. Also the grenade/rocket jumps at the end of the first video to get the rune quicker are smooth as fuck.

Jam it back in, in the dark.

It's only one guy, Sujoy if memory serves. This was first released on Barry's World way back in the depths of time as part of a collection of ridiculous skill videos by predominantly Sujoy and Thresh along with a couple of Swedish players. It's possible he did a level at a time certainly but given some of the other shit I saw him do it's not inconceivable he managed it in one sitting.

I remember seeing a video of his demonstrating exactly why random spawning was needed on Barry's World servers (As opposed to the sequential setup they started out with) by racking up 25 spawn kills in just over a minute. The video was taken from the POV of the person getting fragged and basically every time they spawn there's a rocket in flight heading towards them. You feel pretty sorry for the guy because he really is trying to win, not just standing there waiting for death. I think it was DM3 they were using.

I also saw a video of him grenade-bouncing off a wall after rocket jumping up to it in the middle of one match. The man's a legend.

There's nowhere I can't reach.
