A fun little history of #jbmod: it was based on a debug weapon called the physgun from the leaked hl2 beta. hl2 source code was hacked and stolen before release. gaben said he was impressed and offered to hire the hacker, but when he showed up at the airport he was arrested by the fbi.

I was a part of the community called hl2world that was playing with the hacked unfinished game. I released jbmod on the first day the mod sdk was released and included the physgun code from the leaked source. It was always sketchy in that sense so I thought it would be a bad idea to commercialize it. so yeah garrys mod is based on the same code which was a dev tool from a hacked, unreleased version of the game.
