Portal 2 Announced

The news was revealed via Game Informer, which will be featuring the game on its next cover. No real details have been revealed, although the game will be a "full-fledged, standalone sequel," as opposed to the original, which came packaged with The Orange Box. We should have plenty of good information when the magazine hits newsstands though, as it features a full 12-page spread on the game.

UPDATE: Apparently there’s some kind of crazy co-op mode included, although the source is a now-edited GameStop description, so hmm.

As confirmed by the cover of next month’s Game Informer. GI’s Jeff Marchiafava says:

Our 12-page cover story gives you the first details on Portal 2’s new gameplay mechanics, storyline, and some surprising new twists.

So no, they’re not giving much away. Cheers to Pat for the tip. Official word from Valve saying the game is out “This Holiday Season”, below.
