Portal has updated on Steam. According to the press release they "Added Valuable Asset Retrieval." What does this mean? Well, the ending has changed. For those who might be playing Portal/The Orange Box on the 360 and not Steam here's the video.

Can you say Portal 2? I'm sure you can (hopefully packaged with a certain other anticipated Valve title).

UPDATE: After thinking about this, Valuable Asset Retrieval sounds like something from the G-Man (doubt I'm the first that thought of this) though it may be Aperture Science. Opinions?
