Portal 2 sales have reached 4 million units worldwide, Valve’s David Sawyer has confirmed during an interview with Neogamr (via Game Informer).

In June last year, three months after its April 19, 2011 launch, the game had already sold 3 million units excluding Steam sales. Sawyer did not say whether the new number includes Steam units.

Neogamr also asked Sawyer whether the upcoming PC/Mac puzzle editor would be made availabe to PlayStation 3 and Xbox 360 owners, but those questions “went unanswered,” according to the site.

This will be disc based alone, if it was 3Mil back then without Steam.

Pretty damn good.

I'm glad to hear it. It's maybe my favorite game from last year.

Good to hear, not one of my favourites, but good game non the less.

One of the best games Ive played last year, it was lengthy, had its humor, gameplay and story were great and OST top notch
