    I&apos;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&apos;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&apos;t seem all that fun or didn&apos;t allow for any ellaborate puzzles)

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