Hello!  
I tried a duckroll script that looks like this:

alias +duckroll “alias \_special duckroll;duckroll”  
alias -duckroll “alias \_special”  
alias duckroll “+duck;wait;-duck;wait;special”  
bind key “+duckroll”

I am trying to use it on the WON versions (from 2.4 GoldSrc package) of Half-Life and Opposing Force.  
I don’t know why it doesn’t work because I am not using the Steam versions, which removed special commands. So the code works as expected but it doesn’t loop it because the \_special command doesn’t work (I am using WON versions, remember).

What can I do?
