Puzzling Portal patch arrives on Steam

Valve begins promotion for another title in the series

Posted on Mar 1, 2010 - 7:13pm EST

Today's Portal update, officially, features the following addition: "Changed radio transmission frequency to comply with federal and state spectrum management regulations." Not officially noted there is the new Steam achievement "Transmission Received" which goes undescribed by the developer, but involves the use of Portal's in-game radios.

Also included, as spotted by Steam forumgoers [via Kotaku] are a bunch of new sound files, all prefaced with the word "dinosaur." According to members there, those sound files feature Morse code encoded transmissions.

It wouldn't be surprising if the Half-Life and Left 4 Dead developer was planning a Portal related announcement. If it were to announce Portal 2, we wouldn't be surprised. If it were to announce a sequel to one of its games in its own game, we'd simply be impressed.

Prepare to have your brain and expectations toyed with over the coming weeks, as Valve loves to tease with the most odd and mysterious ways.
