No, in the game console, you can type something like:
bind F1 "+attack;wait 3;-attack;wait 3;+attack;wait 3;-attack;wait 3;+attack;wait 3;-attack;wait 3;"
Then press F1 and you get a cheap three shot bust. Never got that working as well as I like on the FAL though. But I want to know what the wait 3 means in time. 3/10 of a second?
