Valve are up to their old tricks again, concealing tasty teasers in otherwise unrelated blog posts. I like to think of it as Lazy ARG-ing. Bigger announcements would get a scrambled HTML comment that decoded into a website, containing an mp3 that, when run through a spectrograph analyser, would create a map pointing to an abandoned shack in the outer Hebrides, containing a switch that activated thousands of lasers that combined to broadcast a message on the moon. This, the first taste of the GLaDOS announcement pack for Dota 2 , gets a hidden link in a full stop .
Right at the bottom of the Dota 2 blog's International 2013 round-up post , underneath a picture of GLaDOS voice actor Ellen McLain, and at the end of the very last sentence, the full stop that closes the whole thing off links to an mp3 of one of the AI's announcements. Here's an embeddable mirror of the line, courtesy of Reddit :
Dammit guys, we've been pronouncing it wrong this whole time!
During The International, McLain revealed that a GLaDOS pack was being made. This brief sample shows that work on the new lines has already begun. So far, no date has been given for the announcement pack's release.
