Woah!! You were part of hl2world?! Very awesome Garry's Mod is based on the same code from a hacked, unreleased version. I had absolutely no idea, just figured someone knew the unleaked HL2 engine really well and pushed it to the limit. 

That's really shitty of Gaben though... especially getting the hacker's hopes up with a potential job. Same time I remember Valve being up in arms about the HL2 source being grabbed. 

Thank you for the trip down nostalgia lane 😄
