Forget all those alternative endings and teaser hints. It's official - Valve's just announced Portal 2. Although info is tight.
That's all though - it's the starvin' Marvin of annoucements. No info, accept of its "holiday" (summer) release. Literally, that's it.
As previously reported, however, Valve has put out a job advertisement for a voice over role in Portal 2, which amazingly gives up some seemingly spoilerific info on the game's plot. Hit the link above for more on that.
Look out for more info and first shots soon.
