I absolutely love these maps (and most of his maps)... but ugh the backspawning and even backspawning buttons can get annoying. I keep having to tell myself "Made in 97, Made in 97" and a lot of this was a lot more forgivable.
After he did those q2 maps he got employed into the industry as a designer. Can't remember what games he's worked on but he's worked on some decent ones.
Jerk's My "Boss"
He's a cool dude, made a lot of levels for Enclave, Riddick, The Darkness and lots more. He's not really doing level design any more, but he's the game designer for the new Wolfenstein game coming out in a month.
