Aperture NEWS! Portal 2 Getting In-Game Map Editor Next Year

Here's a great announcement!
People loved the recent update Valve brought to Portal 2.

Well, next year you will be able to create your own levels thanks to a future update which will add an in-game editor to Portal!

Valve says the editor will allow users to create both single and co-op stages, and will be “easy to use,” which suggests an interface much simpler than what is usually used to build levels for games.
Players will also apparently be able to “view, play and vote on them [levels] with a simple click.”

And here's some early screens of said editor:

Looks pretty simple and straightforward. I love it already!
