The "Perpetual Testing Initiative" allows players to easily create, share, and play Portal 2 puzzles. The Initiative comes with a simplified puzzle maker that allows that creation of mind-bending puzzles without ever leaving the game.
The puzzle maker can directly publish maps to the Steam Workshop where users can browse, vote on, and select to play them. Selected puzzles will automatically be downloaded and installed inside Portal 2.

So there you have it, folks. The upcoming DLC for Portal 2 is a simplified map maker and integration with the Steam Workshop. While I'm sure many of you were hoping for something a bit more from Valve, at least now you can download and play a ton of user created maps quite easily.
