Posted on October 21, 2011, Phil Owen Valve Confirms New Level Editor for Portal 2
The other day we heard that Valve is working on a new in-game level editor for Portal 2 that would feature commentary by GLaDOS as you create the levels, and Valve today has confirmed part of that report. They sent out a press release announcing that an update for Portal 2 will be released in the new year that will include the editor, but it does not mention GLaDOS at all, and so I don’t know what to think about that particular aspect of the previous report.
It doesn’t matter. This level editor will undoubtedly be mega cool.
