I've also noticed this in the July 09 build but most of these maps are not proper test chambers but more like small gameplay experiment to test mechanics more than anything.<br>Kinda interesting to see how they built everything as time went on

I like how a lot of the ideas that didnt make into the game were made as workshop maps and nobody knew it was already tested by valve or how some maps didnt change a single bit from its orignal creation

gotta say that the portal dev team's reaction to these leaks is entirely correct: <b>all of the best ideas were used for the retail game</b> (the ones cut don't seem all that fun or didn't allow for any ellaborate puzzles)

However, it seemed that it’s taking shape to rework something more portal.
