No, Valve did not tease a new Portal game... But Valve did showcase Enigma Protocol to demonstrate the new Steam Machine!
If you were unaware, Linus Tech Tips was given an early look at the new Steam hardware announced by Valve yesterday. At the 10:26 mark, people spotted an at the time unidentified Portal game running on a nearby monitor.
While I am sorry to say that it looks like Valve isn't working on a new Portal project, I am surprised and delighted to know that Valve enjoys my work enough to use it for promotional content. Enigma Protocol came out nearly 5 years ago now, and I never expected it to have the staying power that it has, let alone being (indirectly) featured by Valve themselves!
If you haven't already, please check out Enigma Protocol on the Steam Workshop!
