How did People in Hl2beta community got 2002-2001 stuff

I see that there's only few 2002 and 2001 stuff in the leak and I wonder where do they get that??, it is all was recreation or just another leak in Facepunch leak or something

The answer is quite simple. Some if not most of those things were already in the leak, some would be recreated years later with models based on leftovers of old textures or old screenshots (or just interpreted), old textures based on their leftovers in old cubemap reflections or old screenshots, with the remaining stuff sometimes leaking overtime in different leaks.

Actually there's only 2003 stuff in the leak, we only have September 2003 build of the game. Although we also have most of sounds and models from 1999-2002 as well.
2001 and 2001-2002 mods in mega build are user-made, based on fixed maps from the WC-mappack from those years. You can also find links for 2002, 2002-2003 and 2003 user-made mappacks in this thread.
