New Portal 2 DLC Announced

Return to Aperture Science this Summer!
Valve have confirmed that a brand new DLC expansion is arriving for Portal 2 later this year. Following their 'Peer Evaluation' multiplayer download, the developers are now building a Level Creator and Editor for the game that will be available exclusively to PC and Mac users. There won't be any major DLC for the actual narrative as far as we can tell (for obvious reasons if you've played it), but you can probably expect some explanation for the new mode too. Portal 2's Level Editor DLC 'Perpetual Testing Initiative' will arrive on May 8th.
