Valve have been known for supporting their games post-release very strongly, but it’s a bit odd that today they released an update for a single-player game with a few hours’ worth of gameplay, which pretty much hasn’t received any updates since it was released over two years ago.
Today’s update’s changelog contained only a single, yet very odd line – “Changed radio transmission frequency to comply with federal and state spectrum management regulations”. Watchful users at Valve’s forums have noticed that there are new sounds playing in the test chambers, and after some digging around the game’s data, it was discovered that the sounds can actually be decoded into images – check out this thread on their forum for a full list of the decoded sounds: [ Link ]
What this all adds up to, we haven’t the slightest idea. Speculations are on fire right now, with the most prominent two suggestions being an upcoming announcement of either Portal 2, or the long-awaited Half-Life 2: Episode 3. Whatever it is, this update surely wasn’t there for random – so keep an eye out!
Oh, and the update also introduced a new achievement to the game, which may give you an incentive to go through it again – so if you own it, might as well fire it up and check it out.
