Not content with teasing us last night with something potentially Apple-related, Valve has also added more tease to Portal.
The latest PC patch for the developer's excellent first-person puzzle game claims it has "Added valuable asset retrieval" - another cryptic description following on from last week's transmission business, which left players scrambling around the game with a radio listening for information.
Following some lightning internet detective work (collated by Rock, Paper, Shotgun - thanks chaps!), fans have uncovered a new end sequence, already on YouTube. It's worth having a watch and listen. What does it all mean? The obvious conclusion is that it's the long-awaited Portal 2, but Valve is likely to keep on teasing until we can't bear it any longer.
