notes are as follows:
Changed radio transmission frequency to comply with federal and state spectrum management regulations
What's this mean? They added a bit of new stuff to the game. Nothing amazing, but most
everyone infers that this hints at upcoming releases (Portal 2, HL2:Episode 3)
The new content:
So long as you have beaten the game once, you'll find radios in the game are changed to have
a red LED on them. When you carry the radio to a part of the level, the LED turns green and a
different (eerily creepy) sound comes from them. There are 26 signals to acquire.
What do they mean? Three are morse code, and the other 23 are images encoded into sound
using SSTV.
That's all I'll say here. There are a lot of other things going on, too, like a BBS that you can
connect to using your computer over a landline telephone for more (encrypted) information.
If you wanna learn more, head over to Steam's Portal forum to check it out.
