Portal caught an update on Steam earlier this week, giving the game an extended ending and teasing some details from the previously announced sequel. Well, it wasn’t officially announced but it was definitely confirmed.

Hidden in the update were all sorts of little clues, the type that keep forum rats busy slaving over cryptic messages to find ASCII art. A lot of the “clues” were actually little jokes from the series, but some of the messages led to ASCII images and several messages from the founder of Aperture, Cave Johnson.

The Steam forums are burning the midnight oil to figure out the meaning behind the messages. I’ll give you a hint, guys – Valve will tell us more soon. Until then you’re going to be looking at a bunch of ambiguous clues pretending you can make sense of them.
