Second piece of Portal 2 DLC incoming, includes map editor

Valve has today announced that Portal 2 will be seeing its second downloadable add-on targeted for release “early next year.” 

This “major” update will add in level creation tools and functionality to the already great Portal 2. The level editor will let players design and share created single-player and co-op test chambers with each other, and the rest of the community. Players can also rate levels based on their quality.

There’s no word about what platforms we can expect this upcoming add-on to come to other than PC, but since Valve built Steamworks into the PlayStation 3, we’d sure be disappointed if this DLC doesn’t hit consoles.
