Portal 2 Puzzle Maker

The Puzzle Maker (also known as Puzzle Creator or Editor) is an in-game puzzle editor that allows the creation, testing, and publishing (to Steam Workshop) of custom single-player and co-op test chambers. The Editor also adds new lines from Cave Johnson which, altogether, adds a story to downloaded test chambers. The DLC introduces the player to "The Multiverse" which contains an infinite number of Earths, an infinite number of Apertures, and therefore, an infinite number of test chambers.
Puzzle Maker is not intended as a replacement of Hammer, which while more powerful and generalized in nature, is significantly more difficult and time consuming to use. It is possible to export a VMF from Puzzle Maker and open it in Hammer; many mappers do this to add polish or features that are not currently possible using the Puzzle Maker. Some mappers use the Puzzle Maker to quickly iterate through (and test) puzzle designs before building a chamber from scratch with Hammer. It is not possible to load a Hammer VMF file in Puzzle Maker.
