A bit more searching and I've found the original thread with the map on it: http://www.halflife2.net/forums/showthread.php?t=91835
It seems that the project was never quite finished, but there's some pretty cool stuff on there.
Very nice :P
OK, think of it this way: if Gordon Freeman had a map in his pocket, it would be a 2D representation of the world he lives in. It's that map that I'm after. Kind of like what you'd get in Doom when you pressed the tab key. I don't know if it exists; it might have been released or...
Is there anywhere where I could download a map of the HL/HL2 universe? I don't mean maps that I can play in the game, I mean a map of the regular levels.
Since HL/2 is linear this won't have much practical value; I'd just like to know how everything fits together.
