Puzzle Creator

The Puzzle Creator (also known as Puzzle Maker or Editor) is a Portal 2 feature released on May 8th, 2012, allowing the creation of single-player test chambers within an in-game map editor. The 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 plan there too, it comes in the form of a simplified level editor [...] a Photoshop for test chambers".

The 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.
