Don’t say Valve never did nothing for the peoples. To celebrate the release of the updated Steam client and it’s launch for the Mac(finally!)Valve is making Portal totally free from today until May 24th. I’m being 100% serious I am downloading it right now on this MacBook Pro that I am typing this story up on. So what are you waiting for? You have a PC or a Mac, right? Oh, you already own Portal? Well, it’s still cool for everyone else right? Don’t be so negative.
