Portal 2 out now on Steam worldwide

Valve digitally delivers.

You can play the PC and Mac versions of Portal 2 two days before launch in UK shops by buying it from Steam.

The release is the result of an alternate reality game that culminated only a few hours ago. Valve has rewarded those who found all 36 potatoes hidden within the Portal 2 ARG with a free copy of the entire Valve Pack on Steam – which includes Portal 2.

UK shops such as GAME still have the first-person puzzler down for release on Thursday 21st April.
