Sorry to revive a 2 month old topic, but I believe I may have also found the rements of weapon 0. (I've got screenshots too!)

While playing in jwklr's server, I started to use Jazz Advantage (a cheating program, for those who don't know, NO I don't use it in regular games) to prove that jwklr wasn't cheating, by showing what the effects of cheating are. While toying with it some, I cycled the weapons and came to one with no image. Shooting caused the trigger to fire, but after that, nothing. The ammo would go down, and when depleted, go back to Electro-Blaster.

Also from a 'Computers are Black Magic' point of view, I think that this may have been from the Tweedle Boss, who suppousedly took away your weapons for the fight.

Anyway, here's my proof http://home.ripway.com/2004-10/185933/weapon0.zip
