Aperture not updating
A cryptic e-mail was sent to members of the press claiming that the Portal 2 World Premiere, scheduled for June 14th at E3, was canceled for a "surprise": Dear Subject Name Here, Aperture Science is pleased to inform you that we have partnered with Valve to announce the gala CANCELLATION of the June 14 Portal 2 event at the Regal Theater. And even though the cancellation of the event certainly counts as a surprise, we are pleased to further announce that the cancellation of the event is not THE surprise.
In that message were actually letters hidden behind their Hexadecimal counterparts, that, after being converted to EBCDIC, resulted in the series "SUSPENDUNTILEEE", thus "suspended until E3", suggesting that no further word about Portal 2 would come from Valve before E3 2010 in June 2010.
When the update was applied, many players launched Portal to see what it was about, and slowly discovered how it consisted in-game, then soon began to investigate the radio sound files on the Steam forums, which led to many intriguing finds.
The error/warning messages and resource names of a resource were always identical each time it was checked by someone.
Playing Portal reveals the game now has a total of 26 radios (including the ones already present before the update) playing in the Test Chambers, always in an area more or less difficult to reach (but given to the player by the music playing), and with a red sprite added to the switch. On April 19, 2011, Portal 2 was released, ending the second ARG, and answering many questions revealed in both ARGs, as text or images.
The radio transmission frequency is also said to have been changed, "to comply with federal and state spectrum management regulations", as said in the update.
It consisted of an additional Achievement, "Transmission Received". Instead of relying on the BBS and the original Portal, this new ARG relied on several indie games, found on Steam as the pack The Potato Sack and all getting an update for the occasion, and where potatoes were to be collected to reboot GLa DOS, among other things.
On June 15, 2010, the second day of E3 2010, Portal 2 was shown as originally planned, but only in Valve's booth, as suggested in the June 1 message.
