As if a
race against time to unlock Portal 2 early wasn’t enough, Valve have been dropping cryptic hints that there’s more to come from the
ARG. A decrypted morse code message hidden in the latest
Steamcast read “it’s not over the others have been compromised.” Later, a message from the mysterious “Doug” alludes to an Aperture Science Icebreaker Ship. The only one of those we know about is the Borealis. The Borealis was last seen seen at the end of Half Life 2: Episode 2. This is getting very exciting indeed.
