Yesterday there was an update to Portal, adding an achievement. There's a lot going on with mysterious pictures and sound files, possibly hinting to Portal 2/HL2:EP3. See the full list of what people are finding out here: Update News! (in first two posts) - Steam Users' Forums -Portal gets surprise update March 1st -People see new mystery achievement -People play and see the radio in the beginning room now has a green light -Carry it around and notice it makes strange broadcast interference noises in certain places -Locate and place all 26 of these mystery radios for achievement -Smart people yank .wav files out of game content folders and run them through SSTV programs [http://i49.tinypic.com/s4b7zn.jpg] [Edit: link should work now. Yes, it's darker than the original.] -Produces 22 cryptic image files in a numbered sequence, 4 morse code -Somebody runs the number string through an md5 hash translator and gets a landline number -Internet traces it to Kirkland, WA (near Valve HQ) -People find out its not a phone/fax line but a data line hosting a BBS and telnet it -Use a clue from one of the files to figure out the BBS user/password login info [backup/backup] -End up with a bunch of weird ASCII artwork:
Another update was released with a new ending. You need to get all the radio's in the new achievement first to see it. Spoiler In the new ending, after blowing up GlaDOS, a robot drags you away somewhere. [ame=https://www.youtube.com/watch?v=YXAq34TrVXM]YouTube - New Portal Ending[/ame]
