The twisted geniuses at Aperture Science Valve have announced plans to release an easy-to-use Portal 2 puzzle editor, called Perpetual Testing Initiative, that will allow players to create, play and share Portal 2 levels without leaving the game.

Player-created puzzles can be published to the Steam Workshop for download and voting, and the top-rated test chambers will be officially added to Portal 2.

The Perpetual Testing Initiative begins May 8.
