Valve has announced the free Portal 2 downloadable content (DLC) titled “Perpetual Testing Initiative” will be available for the PC and Mac on May 8th, 2012. No Xbox 360 or PS3 version was announced.
The “Perpetual Testing Initiative” DLC 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.
Here’s the awesome Portal 2: Perpetual Testing Initiative trailer with Aperture Science founder Cave Johnson explaining how it works.
Next is a video preview of the Portal 2 Community Test Chambers.
