i build my quake like the super hero from thundercats this give a good image in play

and dont forget shoot for the feeds with a fast mouse

alias +rl "impulse 2;wait;impulse 7;wait;+attack;wait"

alias +rl "impulse 7 2;+attack;"

EzQuake is better in scripting than original quake client.

Also it supports conditional variables

see my blog on this site for more.

That work faster than first script imho.
