since nobody is listing the exact filenames:
- demoman.cfg
- engineer.cfg
- heavyweapons.cfg
- medic.cfg
- pyro.cfg
- scout.cfg
- sniper.cfg
- soldier.cfg
- spy.cfg
keep in mind that although these are "configs" they're technically just scripts that get run every time you change to the class. so, if you want to change your sensitivity value for each class, you'll need to enter:
sensitivity 6for every single class, even if you don't want to change it for that class (of course filling in 6 for the value). scripts have no sense of "normal" or resetting values.
