How do you people live with such few weapons? I'm using on average about 15, like Blizzard.
But this is all irrellevant to the topic. Chances are there is no script to enable more than 999 weapons and such, as no one really has a need for it. To be honest, a game with that many weapons would be too overwhelming, and I wouldn't like having to be able to choose between so many different weapons at a time.
