Puzzle Creator

Unreleased

The Puzzle Creator (also known as Puzzle Maker or Editor) is an upcoming feature to Portal 2 that will be available on May 8th, allowing the creation of single-player test chambers within an in-game map editor. Puzzle Creator was first mentioned within The Final Hours of Portal 2, "[An in-game level browser won't be of much use unless] Valve figures out how to make designing Portal 2 maps an easier process. It has a plain there too, it comes in the form of a simplified level editor [...] a Photoshop for test chambers".

Puzzle Creator does not have a single official name; Valve published a blog post on the October 27, 2011 referring to the editor as the "Puzzle Creator", later referred to it on the blog post of April 27, 2012 as "Puzzle Maker" and simply call it "Editor" in-game.
