Valve’s classic puzzler now available free for PC and Mac.
If you haven’t got the chance to test your puzzle-solving skills with Portal, Valve’s original outing of the acclaimed franchise, now it’s your perfect chance to do so – for free.
As part of its “Learn with Portals” initiative, Valve is offering the PC and Mac versions of Portal via Steam completely free of charge, though it’s for a timely limited manner, as the offer runs until September 20.
If for some reason whatsoever, you didn’t play the original Portal in the past four years, go get it, now.
