Valve’s sent out a mysterious email teasing a Portal 2 surprise set to arrive in a little over an hour from press time. The email contains a scanned memo which encourages readers to visit this countdown URL, titled “The Aperture Science Surprise Deployment Initiation System”.
Mentioned in the memo is the “pneumatic tube system,” (pictured) a feature highlighted before launch but non-existent in the final release of Portal 2. Perhaps this is the first bit of downloadable content, with the tubes being the main puzzle element?
We’ll see in about an hour.
Update 9:40pm: Looks like it’s just a thank you video for all those that participated in the Valve ARG. Check it out here.
