Sorry, I should have made it clear in my earlier post.
The leaked source compiles and runs. There are no maps, models or content, but the engine works. It wasn't finished, and there are bugs. That's why it wasn't released yet, right?
All people needed to do to create a working HL2 mod was create the custom models and maps.
